Introduction

Thanks for choosing the DigiTech® SDRUM™ Strummable Drums™ Pedal. The SDRUM is the world’s first intelligent drum machine for guitarists and bassists. The SDRUM provides a quick, fun way to create professional-sounding drum patterns for practice sessions, exploring song ideas, recording, and performing.

There are two ways to create drum patterns with the SDRUM: using the pads or using BeatScratch™, a proprietary technology that allows kick/snare patterns to be created by simply scratching the upper and lower strings of an electric guitar, acoustic guitar (with pickup), or bass. This allows the SDRUM to learn drum patterns using a method commonly used by guitar and bass players to explain a beat to a drummer.

Once a kick/snare pattern is created, the "righthand" drum element (hi-hat, ride, tom, etc.) is automatically added to complement the drum pattern. The right-hand drum element can then be further edited to suit the song.

The SDRUM can learn up to 3 parts per song and store up to 36 songs. Each song and part have various settings that can be adjusted at any time. These include time signature, feel (straight or swing), embellishment amount (how busy the part is), part intensity, tempo, and more.

The SDRUM's drum sounds, from RealiTone™ and Digital Sound Factory®, incorporate samples using multiple velocity layers, for realistic dynamic expression. Tasteful random beat variations, added ghost notes, and humanization keep the drums interesting and provide the feel of a true performance.

The SDRUM offers five drum kits to select from, covering a wide range of genres. Alternate kick/snare sounds are also available for each kit. The drums are internally processed with Lexicon® reverb, so reverb tails decay naturally and are never cut off. All of this means that the SDRUM can generate drum tracks that sound very natural, powerful, organic, and authentic—all with minimal effort and time spent.

1. VERSE/CHORUS/BRIDGE PART Buttons

These PART buttons provide access to the three parts that make up a song, and they serve the following functions:

• Select a Part – Press the PART buttons to switch between each of the three song parts.

• Change Part Intensity – Once a part is selected, repeatedly press the selected PART button to cycle between the available part intensities (or how loud the part will be played). See 'Changing Song Part Intensities' on page 22 for more information.

• Enable the Metronome or Count-In Feature – When playback is stopped, press and hold the currently selected PART button to enable the metronome (when the selected song part is empty) or count-in feature (when the selected song part contains a drum pattern).

The PART buttons have the following states:

• LED Off – The part has not been learned and is not selected.

• LED Solid Dim (Green, Amber, or Red) – With an empty song selected (SONG LED off), this state indicates that the part will be automatically created. For example, when a song is cleared, the VERSE LED will light solid bright amber and the CHORUS LED will light solid dim red, indicating that teaching the verse will automatically create a chorus part. When a non-empty song is selected (SONG LED dim), this state indicates that the part has been learned but is not selected.

• LED Solid Bright (Green, Amber, or Red) – The part is selected.

• LED Flashing (Green, Amber, or Red) – The part has been learned, is selected, and the count-in feature is enabled. The rate of flashing indicates the current tempo of the song. When a part is cleared, the PART button will flash red briefly. When a song is cleared, all three PART buttons will flash red briefly. When a part or song is restored via an undo operation, the buttons will briefly flash green.

Connectors and User Interface

2. TEMPO Button

The TEMPO button provides the following functions:

• Tempo Indication – When a song part is empty and the metronome is on, or if a song part is not empty, the TEMPO LED will flash at the rate of the current song tempo. The TEMPO LED will light red for the first beat of the bar (during playback), dim green for the subsequent beats, then bright green for the subsequent beats of the last bar. If the tempo of a song is changed, the subsequent beats will light amber instead of green to indicate the change. Note that the TEMPO button can be pressed and held to store the new tempo of the song.

• Metronome – With an empty part selected, press and hold the TEMPO button for ~2 seconds to turn the metronome on or off. See 'Using the Metronome' on page 11 for more information.

• Tap Tempo – Tap the TEMPO button at the rate of the desired tempo to change the tempo of a song.

• Update Nominal Tempo – If the tempo of a song is altered using the TEMPO button or TEMPO knob, it will not be automatically stored to the song. To store the updated tempo, press and hold the TEMPO button for ~2 seconds. This will store the new tempo setting as the nominal (center detent TEMPO knob) setting.

See 'Adjusting the Tempo' on page 21 for more information.

3. GROOVE/KIT Encoder Turn then press this encoder to change the drum timing, feel, embellishment amount, and kit. The following options are available:

• Timing – The first two settings select between 3/4 or 4/4 time signatures.

• Feel – The next two settings select between a straight (ST) or swing (SW) feel.

• Embellishment Amount – The next three LEDs select how simple or busy the drum part will be.

• Kit – The remaining LEDs select between the five available drum kits. See 'Selecting the Drum Kit' on page 17 for more information.

4. ALT Button (Kick/Snare)

Press this button to select alternate voicings for the kick and snare:

• LED Off – Standard Voicing

• LED Green – Alternate Voicing

The alternate voicings are different for each drum kit. See 'Selecting Alternate Sounds for the Kick/Snare' on page 18 for more information.

5. LEVEL Knob

This knob adjusts the output level of the drums. Adjust this knob to match the level of the drums to the guitar.

6. LEARN LED

This LED indicates the following functionality:

• Slowly Flashing Red – Indicates an empty song part is selected.

• Rapidly Flashing Red – Indicates the SDRUM is armed for learning and will begin learning the drum pattern once the KICK/SNARE pads are played, the guitar is scratched, or the FOOTSWITCH is pressed.

• Solid Red – Indicates the SDRUM is learning the drum pattern.

Connectors and User Interface

7. KICK/SNARE Pads

When the SDRUM is armed to learn, tapping these pads provides a traditional method for teaching drum patterns. They can also be used when using the SDRUM with an instrument that doesn't have a pickup. See 'Teaching Drum Patterns with the Kick and Snare Pads' on page 12 for more information.

8. SONG Button

Press this button and turn the HATS/RIDES encoder to select a different song. Song selections are displayed on the LEDs surrounding the HATS/RIDES encoder. Turn the HATS/RIDES encoder to select a song from one of the three banks (green, amber or red LEDs), then press the SONG button or HATS/RIDES encoder to load the song. See 'Managing Songs' on page 24 for more information on creating, loading, and copying songs.

9. HATS/RIDES Encoder

Turn this encoder to select a different variation on how the right-hand drum element is played. Press this encoder to select between different sub-beat timing options for the right-hand drum element. See 'Selecting Right-Hand Drum Elements' on page 19 for more information on the available options and using the HATS/RIDES encoder.

10. ALT Button (Hats/Rides)

Press this button to select alternate voicings for the right-hand drum element:

• LED Off – Standard Voicing

• LED Green – Alternate Voicing 1

• LED Red – Alternate Voicing 2

The alternate voicings are different for each drum kit. See 'Selecting Alternate Sounds for Right-Hand Drum Elements' on page 20 for more information.

11. TEMPO Knob Turn this knob to change the tempo of the song. The tempo range is from half-speed (fully counterclockwise) to double speed (fully clockwise). To store the changed tempo of a song, press and hold the TEMPO button for ~2 seconds. The center detent position of the TEMPO knob represents the tempo stored to a song.

NOTE: Whenever the tempo is changed without directly using the TEMPO knob—for example, when teaching a new drum pattern, loading a new song, or using tap tempo—the TEMPO knob may need to be moved back to the center detent position before it becomes active again. This prevents sudden tempo changes if the knob is nudged when the current position does not match the current tempo.

See 'Adjusting Tempo Using the Tempo Knob' on page 21 for more information.

12. PLAY LED

This LED indicates the following functionality:

• LED Off – Indicates the selected song part is empty.

• LED Dim Green – Indicates the selected song part contains a drum pattern and playback is stopped.

• LED Bright Green – Indicates the SDRUM is playing the song.

• LED Flashing – The PLAY LED flashes along with the KICK and SNARE pads when the FOOTSWITCH is held down to stop playback.

Connectors and User Interface

13. GUITAR AUDITION Button

Press this button to cycle through the Guitar Audition modes. Press and hold this button to calibrate BeatScratch for a guitar (see 'Teaching Drum Patterns with a Guitar or Bass' on page 13 for more information on calibrating BeatScratch). This button has three states:

• Off (LED Off) – The guitar will be heard when played.

• Hybrid (LED Dim) – When an empty song part is selected, kick/snare sounds will be heard when scratching the guitar so that BeatScratch can be used. When a song part that contains a drum pattern is selected, the guitar will be heard when played so that you can play along with the drums.

• On (LED Bright) – Kick/snare sounds will always be heard when scratching the guitar.

NOTE: The Guitar Audition feature will be automatically enabled (LED bright) after calibrating BeatScratch. After creating a drum pattern, the Guitar Audition feature will be automatically set to "Hybrid" mode (LED dim).

14. FOOTSWITCH

This footswitch provides the following functions:

• Arm for Learning – When an empty song part is selected, press the FOOTSWITCH once to arm the SDRUM to learn a new drum pattern (LEARN LED will flash rapidly). Play the part, or press the FOOTSWITCH again to force the SDRUM to begin learning the new drum pattern.

• Start Playback – When playback is stopped and a song part is learned and selected, press the FOOTSWITCH once to begin song playback.

• Stop Playback – During playback, press and hold the FOOTSWITCH for ~2 seconds (or until the KICK and SNARE pads begin flashing rapidly) to stop playback. Release the FOOTSWITCH as soon as the KICK and SNARE pads begin flashing to stop the song without a sustaining crash cymbal. Continue holding the FOOTSWITCH to end a song with a sustaining crash cymbal. Note that the cymbal crash will decay naturally until the FOOTSWITCH is released or the sustain rings out.

• Clear a Part and Undo – When playback is stopped, press and hold the FOOTSWITCH for ~2 seconds (or until the selected PART button begins to flash rapidly), then release. The selected song part will now be empty. Immediately press and hold the FOOTSWITCH again for ~2 seconds to restore the cleared part.

• Clear a Song and Undo – When playback is stopped, press and hold the FOOTSWITCH for ~4 seconds (or until all PART buttons begin to flash rapidly), then release. All parts of the song will now be empty. Immediately press and hold the FOOTSWITCH again for ~2 seconds to restore the cleared song.

NOTE: The currently selected part will be cleared first when clearing a song, but as long as the FOOTSWITCH continues to be held, then all song parts will be cleared at once.

Operation Description

A mono mix of the guitar and drum signal will be sent to the AMP OUT jack.

Complementary equalization will be applied to the drum signal to make it sound better when played through a guitar amp.

NOTE: When using a guitar amp to play the drums from the SDRUM, set the amp to run as cleanly as possible in order to avoid distorting the drums. The drums are pre-EQ'd to sound best through a clean amp with "flat" EQ settings. If using guitar effects and/or a looper, they should be placed before the SDRUM when using only the AMP OUT jack.

The drum and guitar signals will be mixed and sent to the MIXER OUT jacks.

If only the left (mono) MIXER OUT jack is connected, the guitar/drum mix will be mono. If the left and right MIXER OUT jacks are connected, the guitar signal will be mono and the drum signal will be stereo.

NOTE: The SDRUM does not apply cabinet simulation to the guitar signal. This allows an acoustic or bass guitar to be used when only the MIXER OUT jacks are connected.

The guitar signal will be fed to the AMP OUT jack only. The drum signal will be sent to the MIXER OUT jacks in mono (if only the MIXER OUT L jack is used) or stereo (if both MIXER OUT jacks are used). If using guitar effects and/ or a looper, they can be placed before or after the SDRUM when using both the AMP OUT and MIXER OUT jacks.

Making Connections and Applying Power

To connect the SDRUM pedal:

1. Turn down the guitar amp. If connecting to a mixer, turn down the gain/trim controls and lower the faders on the channels to which you are connecting.

2. Make all connections to the SDRUM as shown in 'Connection Diagrams' on page 8.

3. Connect the included HARMAN power adapter to the SDRUM POWER input connector, then connect the

other end to an available AC outlet and wait for the SDRUM to boot.

4. Turn the guitar volume all the way up, strum the guitar, and then gradually increase the guitar amp volume until the desired level is achieved. If using a mixer, set the channel faders to unity (0), then raise the gain/ trim controls while tapping the KICK/SNARE pads for the desired level. Set the LEVEL knob to 12 o'clock.

Teaching Drum Patterns

The SDRUM allows drum patterns to be created in one of two ways: using BeatScratch to naturally scratch drum patterns with a guitar or bass, or using the KICK and SNARE pads, which also allows the SDRUM to be used with other instruments that don't have a pickup.

When teaching a new drum pattern, the SDRUM will automatically determine the time signature and feel (straight or swing) settings. Once a new drum pattern has been taught, the detected time signature and feel settings will be reflected on the LEDs surrounding the KIT/GROOVE encoder. The KIT/GROOVE encoder can then be used to change the time signature and feel manually if desired.

TIP: If required, the automatic time signature/feel detection of the SDRUM can be overridden and a predetermined time signature and/or feel can be pre-selected before teaching a new drum pattern. See 'Pre- Selecting Timing and Feel Settings' on page 28 for more information.

By default, when teaching the SDRUM a new song, the verse is selected as the active part and, once the verse drum pattern is learned, the chorus part is automatically generated with drums having the same kick/snare pattern as the verse, but with a higher intensity and a cymbal pattern instead of the default hi-hats. This behavior is indicated on the user interface with the VERSE LED lighting solid bright amber and the CHORUS LED lighting solid dim red.

This means that by teaching a single drum pattern for the verse part, you then have drum patterns for two song parts, allowing you to instantly start exploring song ideas. If you prefer, you can overwrite the automatically generated chorus drum pattern with your own, disable the chorus part (CHORUS LED off) before teaching the verse part, or automatically generate a bridge part as well when the verse part is created (see 'Automatically Generating a Bridge Drum Pattern' on page 27).

Using the Metronome

The built-in metronome can be used to improve timing and avoid unexpected results when teaching a new drum pattern, as well as to match the tempo of all parts that make up a song. The metronome is automatically enabled whenever at least one song part has been learned and an empty song part is selected.

To enable/disable the metronome:

1. Select an empty song part (the LEARN LED should be flashing).

2. Press and hold the TEMPO button for ~2 seconds to enable/disable the metronome. The TEMPO button

will also flash at the rate of the metronome to provide visual tempo indication.

TIP: Pressing and holding the currently selected PART button when the part is empty provides an alternate way to enable/disable the metronome.

TIP: The tempo can be changed before teaching the new drum part by either tapping in the desired tempo on the TEMPO button or by turning the TEMPO knob.

NOTE: The default BPM for an empty song is 120. The SDRUM always plays back at an integer BPM,

making it easier to match the BPM of an external device or DAW.

NOTE: In a song where at least one part has already been learned, the metronome will automatically be enabled when an empty part is selected.

Teaching Drum Patterns

Teaching Drum Patterns with the Kick and Snare Pads

The KICK and SNARE pads on the SDRUM can be used to teach drum patterns in a more traditional manner or when playing an instrument without a pickup.

To teach a drum pattern with the KICK and SNARE pads:

1. Ensure an empty song part (VERSE, CHORUS, or BRIDGE) is selected. The LEARN LED will flash if the selected part is empty.

TIP: When an empty song is selected (SONG LED off), the VERSE LED will light solid bright amber and the CHORUS LED will light solid dim red. This indicates that teaching the verse will automatically generate a chorus part. If you wish to create a custom pattern for the chorus part instead, disable the automatic part generation feature before teaching the SDRUM by pressing the CHORUS button repeatedly until the CHORUS LED turns off. Note that the automatically generated chorus part can also be cleared and a new pattern taught after teaching the SDRUM if preferred.

For information about automatically generating a bridge drum pattern along with the verse and chorus, see 'Automatically Generating a Bridge Drum Pattern' on page 27.

2. If desired, enable the metronome by pressing and holding the TEMPO button for ~2 seconds. Set the tempo by tapping the TEMPO button at the desired rate or by turning the TEMPO knob.

3. Press the FOOTSWITCH to arm the SDRUM. The LEARN LED will begin flashing rapidly to indicate the SDRUM is armed.

4. Begin playing the drum pattern on the KICK and SNARE pads.

TIP: Alternatively, press the FOOTSWITCH to start learning without needing a pad hit. The LEARN LED

will light solid red, indicating that the SDRUM is learning. This can be useful for certain music styles that incorporate drum patterns that have no kick or snare hit on the first downbeat of the bar, such as reggae.

NOTE: When creating a new drum pattern, the maximum length cannot exceed 4 bars.

5. Press the FOOTSWITCH when done. For best results, try to press the FOOTSWITCH on the same downbeat

you started on (beat 1).

6. The drum pattern will begin playing. Play the guitar and adjust the LEVEL knob for a good blend between the guitar and drums.

7. To stop playback, press and hold the FOOTSWITCH for ~2 seconds (until the KICK and SNARE pads begin flashing). Releasing the FOOTSWITCH as soon as the KICK/SNARE pads begin flashing will stop playback. Continuing to hold the FOOTSWITCH will cause a crash cymbal to play at the end of the current bar and ring out for as long as the FOOTSWITCH is held.

TIP: The SDRUM offers some advanced features that can enhance SDRUM operation when creating a drum pattern. See 'Advanced Features and Tips' on page 27 for more information on the options available and how to use them.

Teaching Drum Patterns

Teaching Drum Patterns with a Guitar or Bass

The all-new BeatScratch feature allows a guitar or bass to be used to teach the SDRUM a drum pattern. When doing so, the SDRUM should first be calibrated for the connected guitar/bass.

To calibrate BeatScratch for a guitar/bass:

1. Adjust the guitar/bass pickup position and tone control for the desired tone.

2. Press and hold the GUITAR AUDITION button for ~2 seconds. The KICK pad will begin flashing and the HATS/RIDES LEDs will all turn red. Keep the guitar/bass quiet until you're ready to begin the calibration

process.

3. Mute the strings with your fret hand, then strum only the low strings in the way that you wish to teach kick drum hits. With each detected hit, the HATS/RIDES LEDs will go off one by one. Stop once all twelve kick events have been received (all the HATS/RIDES LEDs will go off, the SNARE pad will begin flashing, and the

HATS/RIDES LEDs will all light red again).

4. Mute the strings with your fret hand, placing your hand in the same position on the neck used for the kick

calibration, then strum only the high strings in the way that you wish to teach snare drum hits. With each detected hit, the HATS/RIDES LEDs will go off one by one. Once twelve snare events have been received (all the HATS/RIDES LEDs have gone off ), the SDRUM will exit calibration mode.

5. Once calibration is complete, scratching the guitar/bass will generate kick and snare sounds.

NOTE: Calibration settings are retained, even after a power cycle.

TIP: If playing bass, try using a pick if fingering or plucking the strings is not working. Feel free to experiment

with different ways of teaching the SDRUM to discover what works best with your instrument and teaching style. Some bass players have found that slapping the lowest string and popping the highest string works well.

Teaching Drum Patterns

To teach a drum pattern with a guitar/bass:

1. If the guitar/bass has not yet been calibrated to use BeatScratch, first follow the calibration instructions above before proceeding.

2. Ensure an empty song part (VERSE, CHORUS, or BRIDGE) is selected. The LEARN LED will flash if the selected part is empty.

For information about automatically generating a bridge drum pattern along with the verse and chorus, see 'Automatically Generating a Bridge Drum Pattern' on page 27.

3. If desired, enable the metronome by pressing and holding the TEMPO button for ~2 seconds. Set the tempo by tapping the TEMPO button at the desired rate or by turning the TEMPO knob.

4. Press the FOOTSWITCH to arm the SDRUM. The LEARN LED will begin flashing rapidly to indicate the SDRUM is armed.

5. Begin playing the drum pattern by scratching the guitar/bass.

TIP: Alternatively, press the FOOTSWITCH to manually initiate SDRUM learning. The LEARN LED

will light solid red, indicating the SDRUM is learning. This can be useful for certain music styles that incorporate drum patterns that have no kick or snare hit on the first downbeat of the bar, such as reggae.

NOTE: When creating a new drum pattern, the maximum length cannot exceed 4 bars.

6. Press the FOOTSWITCH when done. For best results, try to press the FOOTSWITCH on the same downbeat

you started on (beat 1).

TIP: The SDRUM offers some advanced features that can enhance SDRUM operation when teaching drum patterns. See 'Advanced Features and Tips' on page 27 for more information on the options available and how to use them.

Selecting Drum Pattern Settings

Selecting the Time Signature

The SDRUM has two time signature settings to select from: 3/4 and 4/4. The time signature can be changed on a single song part or for an entire song.

To change the time signature of parts:

1. Select the song part using the VERSE, CHORUS, or BRIDGE button.

2. Turn the GROOVE/KIT encoder to select the new time signature.

3. Press the GROOVE/KIT encoder to make the selection. To change the time signature setting for all song

parts, press and hold the GROOVE/KIT encoder for ~2 seconds (until the selected time signature LED flashes three times).

TIP: The time signature setting can also be pre-selected before teaching the SDRUM a drum pattern. See 'Pre-Selecting Timing and Feel Settings' on page 28 for more information.

Selecting the Feel

The SDRUM offers two feel settings to select from: straight (ST) or swing (SW). The feel can be changed on a single song part or for an entire song.

To change the feel of parts:

1. Select the song part using the VERSE, CHORUS, or BRIDGE button.

2. Turn the GROOVE/KIT encoder to select the new feel setting.

3. Press the GROOVE/KIT encoder to make the selection. To change the feel setting for all song parts, press and hold the GROOVE/KIT encoder for ~2 seconds (until the selected feel LED flashes three times).

TIP: The feel setting can also be pre-selected before teaching the SDRUM a drum pattern. See 'Pre-Selecting

Timing and Feel Settings' on page 28 for more information.

Selecting Drum Pattern Settings

Selecting the Embellishment Amount

The embellishment amount setting determines how simple or busy the drum pattern will be. The SDRUM has three embellishment amount settings: SIMPLE, INTERMEDIATE, and BUSY.

Embellishment Amount Setting Description

With this option selected, only the kick/snare (or equivalent) drum

SIMPLE

elements that were taught to the part will be played (there will be no added ghost notes or extra drum hits).

INTERMEDIATE

BUSY

The embellishment amount setting can be changed on a single song part or for an entire song.

To change the embellishment amount of parts:

1. Select the song part using the VERSE, CHORUS, or BRIDGE button.

2. Turn the GROOVE/KIT encoder to select the new embellishment amount setting.

3. Press the GROOVE/KIT encoder to make the selection. To change the embellishment amount setting for

all song parts, press and hold the GROOVE/KIT encoder for ~2 seconds (until the selected embellishment amount LED flashes three times).

With this option selected, some ghost notes and occasional extra drum hits will be added to keep the drum pattern interesting.

With this option selected, a pattern will be more complex with extra notes being added to the kick/snare and variation patterns.

Selecting Drum Pattern Settings

Selecting the Drum Kit

The SDRUM offers five drum kits to choose from:

Drum Kit Description

E-POP

BRUSH

PERCUSSION

POWER

CLEAN

All kits, with the exception of E-Pop, feature multiple velocity layers for all main drums (kick, snare, hi-hats, toms, cymbals). This means that different samples are used depending on how loud each drum is played, which allows sampled drums to sound much more realistic. E-Pop is an exception because synthesized drum machines do not typically alter the tone of a drum based on velocity.

The drum kit can be changed on a single song part or for an entire song.

This kit is made from synthesized drum sounds that emulate analogue drum machines.

This is a vintage-sounding kit played with brushes, for jazz and folk music styles. This kit also includes shaker and tambourine samples.

This kit is an augmented clean drum kit with a cowbell, clave, timbales, and congas. It is designed for latin fusion music styles.

This is a drum kit designed for hard rock, metal, and punk music styles, with a more aggressive sound than the clean kit.

This is a clean drum kit, suitable for rock, pop, and country music styles.

To change the drum kit on parts:

1. Select the song part using the VERSE, CHORUS, or BRIDGE button.

2. Turn the GROOVE/KIT encoder to select the new drum kit setting.

3. Press the GROOVE/KIT encoder to make the selection. To change the drum kit setting for all song parts, press and hold the GROOVE/KIT encoder for ~2 seconds (until the selected kit LED flashes three times).

TIP: The drum kit setting can be changed before or after teaching a new pattern.

Selecting Drum Pattern Settings

Adjusting the Tempo

The tempo of a song can be adjusted either before or after teaching the SDRUM, and it can be adjusted using the TEMPO button (tap tempo) or TEMPO knob.

After a part has been learned, or if the metronome feature is enabled, the TEMPO button will flash at the current tempo of the song. The TEMPO button will flash red on the first beat of each bar (only during playback) and green for the remaining quarter note beats if the tempo of the song has not been edited. If the tempo has been edited from the song's stored value, the TEMPO button LED will flash amber instead of green. If the tempo is changed by some mechanism other than the TEMPO knob (e.g., using tap tempo or loading a new song), then the TEMPO knob will not function until it is turned past the center detent (stored) position.

When a part is being played, during the last bar of the part, the TEMPO button will flash brighter to indicate that the drum pattern loop is coming around to the beginning.

Adjusting Tempo Using the Tempo Button

To adjust a song's tempo with the TEMPO button:

1. Play the song.

2. Tap in the desired tempo on the TEMPO button.

3. The TEMPO button will now flash amber, indicating that the new tempo differs from that stored with the

song.

TIP: To restore the original tempo, rotate the TEMPO knob a quarter turn above or below the center detent position and then return it to the detent position.

4. Press and hold the TEMPO button for ~2 seconds to store the new tempo setting to the song. The TEMPO LED will again flash green to indicate this is the song's stored tempo (center detent position on the TEMPO knob).

Adjusting Tempo Using the Tempo Knob

The TEMPO knob's center detent position represents a tempo multiplier of 1X, which is the original tempo of the learned song part. The full clockwise position provides a tempo of 2X the learned tempo and the full counterclockwise position provides a multiplier of 1/2X the learned tempo.

To adjust a song's tempo with the TEMPO knob:

1. Play the song.

2. Turn the TEMPO knob to change the tempo. Note that the TEMPO knob may have to be turned past the

center detent position before changes will be made. The TEMPO button will now flash amber, indicating that the new tempo differs from that stored with the song.

TIP: To restore the original tempo, rotate the TEMPO knob back to the center detent position..

3. Press and hold the TEMPO button for ~2 seconds to store the new tempo setting to the song. The TEMPO

LED will again flash green to indicate this is the song's stored tempo (center detent position on the TEMPO knob).

Using Song Parts

The SDRUM's three song parts (verse, chorus, and bridge) make up a song. Each part can be programmed for lower or higher intensity to add dynamics to the song. Learned parts are automatically stored to memory until cleared, even after a power cycle.

Changing Song Part Intensities

The intensity of each song part can be changed to create song dynamics for a more energetic performance.

There are three part intensities available:

Part LED Description

Green

Low Intensity

Amber

Medium Intensity

Red

High Intensity

To change the intensity of a song part:

1. Select the part to edit by pressing the VERSE, CHORUS, or BRIDGE button (the LED that is brightest indicates selection).

2. Press the selected PART button repeatedly to cycle intensity selection.

Playing and Switching between Song Parts

To play and switch between song parts:

1. Select the first part to be played using the PART (VERSE, CHORUS, and BRIDGE) buttons.

2. Tap the FOOTSWITCH to start playing the song part.

3. While the song is playing, tap the FOOTSWITCH to advance to the next part, or press one of the PART

buttons to cue another part to be played. The cued PART button will flash at its learned tempo, a drum fill will be played, then the next part will begin playing at the start of the next bar. The optional FS3X Footswitch can also be used to switch song parts. See 'Using an FS3X Footswitch' on page 33 for more information.

TIP: Press the FOOTSWITCH twice to skip a part—for example, to go from playing part 1 (the verse) to part 3 (the bridge). To play a drum fill but stay on the current part, tap the FOOTSWITCH repeatedly until the current part is selected again.

Using Song Parts

Stopping Playback and Ending a Song

To stop song playback:

1. During playback, press and hold the FOOTSWITCH for ~2 seconds (or until the PLAY LED and KICK/SNARE pads begin flashing).

2. Release the FOOTSWITCH as soon as the PL AY LED and KICK/SNARE pads begin flashing to stop playback immediately. Or, continue to hold the FOOTSWITCH to finish the bar and then end the song with a crash cymbal. Keep the FOOTSWITCH held to allow the crash cymbal to decay naturally.

Clearing a Song Part

To clear a song part:

1. Stop playback by pressing and holding the FOOTSWITCH for ~2 seconds (or until the PL AY LED and KICK/ SNARE pads begin flashing).

2. Select the part to clear by pressing the VERSE, CHORUS, or BRIDGE button. The brightest LED indicates

the part selected.

3. Press and hold the FOOTSWITCH for ~2 seconds (or until the currently selected PART button flashes red rapidly), then release. The LEARN LED will begin flashing slowly, indicating the part is empty. Make sure to release the FOOTSWITCH as soon as the current PART LED begins flashing, as holding the FOOTSWITCH down for ~4 seconds will clear the entire song.

TIP: A part can be restored as long as the SDRUM has not been power cycled or any other operations performed since the part was cleared.

To restore a part after clearing it, immediately press and hold the FOOTSWITCH for ~2 seconds (or until the currently selected PART button flashes green rapidly), then release. The LEARN LED will go off and the PL AY LED will light to indicate the part is again available.

TIP: If the SilentClear feature is enabled, song parts can be cleared without momentarily initiating playback. See 'Enabling Count-In and SilentClear' on page 27 for more information.

NOTE: When a part is cleared, if the song still contains at least one learned song part, a metronome will begin playing at the tempo of the last played song tempo, making it easy to match the tempo of all song parts.

Managing Songs

The SDRUM can store up to 36 songs with up to 3 parts each. Songs are automatically stored in real time. The following sections describe how to create, load, copy, and clear songs.

WARNING: To ensure that song data is not unexpectedly lost, always stop SDRUM playback and wait at least 5 seconds, without making any song changes, before powering down the pedal.

6. Repeat steps 3 and 4 to clear any additional songs.

Advanced Features and Tips

Enabling Count-In and SilentClear

The SDRUM has a count-in feature that can be used to provide a 1-bar drumstick count-in before a song begins playing. When the count-in feature is enabled, so is SilentClear. The SilentClear feature allows songs or song parts to be cleared without momentarily initiating playback.

To enable/disable the count-in and SilentClear features:

NOTE: The SDRUM must be taught at least one song part for the count-in feature to become available.

1. With playback stopped, press the PART (VERSE, CHORUS, or BRIDGE) button to select the first part that

will be played for the song. The button for the currently selected part will be brighter than all the others.

2. Press and hold the currently selected PART button for ~2 seconds to toggle the count-in/SilentClear features on or off. The PART button will begin flashing at the rate of the selected part's tempo when the features are enabled.

3. Press the FOOTSWITCH to start the count-in.

4. After the 1-bar count-in, the selected part will start playing and you can play along with it.

NOTE: When enabling or disabling the count-in and SilentClear features, the setting will be remembered,

even after changing songs and power cycling the SDRUM.

Automatically Generating a Bridge Drum Pattern

You may have noticed that, by default, the SDRUM automatically generates a chorus drum pattern whenever you teach it a verse drum pattern. This is indicated by the VERSE LED lighting solid bright amber and the CHORUS LED lighting solid dim red when an empty song is selected (SONG LED off). Although the chorus pattern is generated automatically by default, the bridge pattern is not and must either be taught separately, once the verse/chorus has been taught, or enabled to be taught along with the verse and chorus.

To automatically generate a bridge drum pattern when teaching the verse and chorus parts:

1. Select an empty song. See 'Creating a New Song' on page 24 for instructions.

2. Press the BRIDGE button. The button should now be lit.

3. Press the VERSE button to again select the verse part to teach. The BRIDGE button will now light dim

green, indicating it will automatically be taught a part when the verse is taught.

4. Teach the verse drum pattern. When done, a complete song with verse, chorus, and bridge will be created.

TIP: The automatically generated bridge drum pattern will mirror the verse drum pattern. Try changing the

right-hand drum element using the HATS/RIDES encoder to differentiate it from the verse. For example, change from a hi-hat to a ride cymbal and change the sub-beat timing. Note that settings can also be preselected before teaching drum patterns. See the following pages for more information.

TIP: Automatically generated chorus and bridge drum patterns can be cleared if you decide to create custom patterns for those parts after teaching. See 'Clearing a Song Part' on page 23 for more information.

Advanced Features and Tips

Pre-Selecting Timing and Feel Settings

In most cases, the SDRUM does a great job of automatically determining the timing and feel when learning a new drum pattern. However, if you are teaching the SDRUM a drum pattern and aren't getting the expected results, you may need to override the SDRUM's automatic detection and select a specific timing and/or feel setting before teaching it the new pattern.

To pre-select timing/feel before teaching a new drum pattern:

1. Select an empty song part using the VERSE, CHORUS, or BRIDGE button. The LEARN LED should be flashing, indicating the part is empty.

2. Turn the GROOVE/KIT knob to select the desired time signature (3/4 or 4/4) and/or feel (ST (straight) or SW (swing)), then press the GROOVE/KIT encoder.

3. The pre-selected timing and/or feel LED will now flash, indicating that it will override the automatically detected timing or feel.

NOTE: Pre-selected settings are global, meaning that once settings are pre-selected, they will be used for teaching all parts within the song.

TIP: To turn automatic detection back on, simply select the time signature or feel setting that is flashing, then press the GROOVE/KIT encoder.

Teaching an Entire Song At Once

Using the advanced SDRUM features described in this section of the manual, an entire song can be created by teaching only the verse part. Simply pre-select the desired timing and feel settings with the GROOVE/KIT encoder, then press the BRIDGE button to enable the bridge part to be learned with the verse and chorus. You can even pre-select the A LT options and HATS/RIDES settings for each part. Arm the SDRUM to learn, then teach the verse drum pattern. That's it! A complete song is now available to jam and experiment with.

Teaching Special Drum Patterns

Teaching a Difficult Pattern

If you aren’t getting the results you want when teaching a drum pattern, try turning on the metronome and setting the tempo to the one you want. Also, teaching 2 bars will generally give more accurate results than teaching a single bar. Also, try pre-selecting the feel (straight or swing) and/or timing (3/4 or 4/4). Another trick is to first slow down the tempo, then teach the drum pattern at the slower BPM. After the drum pattern has been learned, speed up the tempo to the desired BPM.

Teaching a Pattern with No Kick or Snare on Beat 1

Some drum patterns, most notably many reggae styles, don’t have a kick or snare hit on the first beat. To teach this type of pattern, first enable the metronome. Now, arm the SDRUM to start learning by pressing the FOOTSWITCH, but instead of starting the learning process with a guitar scratch or pressing a drum pad, press the FOOTSWITCH again. The LEARN LED will light solid red, indicating the SDRUM is learning. Continue teaching the rest of the pattern, pressing the FOOTSWITCH again on beat 1 to stop the learning process. The pattern will now play and will have no kick or snare on the first beat.

Teaching a Pattern with No Kick or Snare

There are cases where you might want to create a pattern with no kick or snare—for example, maybe you want quarter note hi-hats, a shaker, or a tambourine only. To create this type of pattern, first enable the metronome. Now, arm the SDRUM to start learning by pressing the FOOTSWITCH, but instead of starting the learning process with a guitar scratch or pressing a drum pad, press the FOOTSWITCH again. The LEARN LED will light solid red, indicating the SDRUM is learning. Count off one or two bars, then press the FOOTSWITCH again. As long as one or more full bars were taught, the SDRUM will play a pattern that contains only the right-hand drum element. Try experimenting with different HATS/RIDES options to further tailor the pattern for your song.

Teaching a Pattern with Kick and Snare on the Same Beat

There is no way of using a guitar to teach the SDRUM a pattern with a kick and snare on the same beat. However, this can easily be accomplished using the KICK and SNARE pads. When pressed together, both the kick and snare will be learned in the pattern.

Teaching a Half-Time Shuffle Pattern

Another common pattern is the half-time shuffle. The best way to teach this pattern is to first pre-select a 4/4 time signature and a swing feel, then enable the metronome. Next, teach the kick/snare pattern and skip one beat between each kick and snare.

Example:

Bar 1 Bar 2

1 & 2 & 3 & 4 & 1 & 2 & 3 & 4 &

• • • • • • • • Metronome beats

K S K S What you teach

Play around with different kick/snare patterns to get the desired sound. As long as the basic kick/snare pattern is based around every other metronome beat, you should be able to get a shuffle beat that works.

Teaching Special Drum Patterns

Teaching a 6/8 Ballad Pattern

Many songs have a 6/8 time signature, where the kick is on beat 1 and the snare is on beat 4. To get this type of beat with the SDRUM, turn on the metronome and set the tempo to the desired BPM. Pre-select a 3/4 time signature to make sure the beat is interpreted correctly. Then teach the SDRUM a 2-bar pattern in 3/4 with the kick on beat 1 of the first bar and the snare on beat 1 of the second bar.

Example:

Bar 1 Bar 2

1 & 2 & 3 & 1 & 2 & 3 &

• • • • • • Metronome beats

K S What you teach

This will essentially provide a 6/8 pattern. Pick the hi-hat pattern that best fits the song. Also, switch between the swing and straight settings to set the desired feel for the song.

Teaching a Classic Train Beat Pattern

A train beat is a classic kick/snare pattern used especially in country, folk, and bluegrass music. Because it would be almost impossible to teach this iconic beat using a guitar or the built-in pads, a special detection mode has been included in the SDRUM.

To get a train beat, count out four beats for each bar, then scratch a snare (or use the snare pad) to teach a snare on every eighth note beat. For example, try a 2-bar pattern with 16 consecutive evenly spaced snare hits on the 1 & 2 & 3 & 4 & beats for each bar. Also, try enabling the metronome and lowering the tempo to see if that helps— the tempo can be raised back up after the pattern is learned. If you teach this special pattern, you will get a train beat with kicks and snares.

Example:

Bar 1 Bar 2

1 & 2 & 3 & 4 & 1 & 2 & 3 & 4 &

• • • • • • • • Metronome beats

S S S S S S S S S S S S S S S S What you teach

Teaching a Typical Brush Swirl Jazz Pattern

When the BRUSH kit is selected, the HATS/RIDES variation #2 option provides a brush swirl sound, as well as pedal hi-hats. When teaching a typical brush swirl pattern, snare hits should not be played because the pedal hi-hats will act in place of the snare. To teach this type of pattern, pre-select the BRUSH kit and the HATS/RIDES variation #2 option (press the HATS/RIDES encoder repeatedly until the LED is green, if it isn't already). It may also help to pre-select the 4/4 time signature and SW (swing) options, and slow down the tempo.

Example:

Bar 1 Bar 2

1 & 2 & 3 & 4 & 1 & 2 & 3 & 4 &

• • • • • • • • Metronome beats

K K K K K K What you teach (swing those

kick beats just before beat 3!)

You should now hear a brush swirl, with pedal hats on the 2 and 4 beats.

NOTE: When cascading audio through multiple JamMan loopers in series and using JamSync (as shown in the diagram above), the SDRUM (the master) should be last in the chain in most cases. You will then want to teach the SDRUM first, then record to the second to last device, etc., working backwards through the signal chain. Performing these actions will ensure you record only what you intend to during each pass.

You can reverse this order if you like, but then when you record on the first slave, you'll be recording a mix of your live guitar and whatever the master is playing back, and so on down the line. When using the AMP OUT and MIXER OUT jacks, you can place the SDRUM before or after the loopers and effects, whichever works for you, since the drums don't come out of the AMP OUT jack.

To connect JamSync devices:

1. Connect the SDRUM’s JAMSYNC OUT jack to the JAMSYNC IN jack of the first slave device. Depending on the JamMan looper used, the REC and PL AY LEDs on the slave device may briefly flash or the display may change to indicate the unit is in slave mode.

2. Daisy-chain any remaining JamSync slaves in the same manner.

Using JamSync

Teaching the SDRUM and Recording Loops

When using a JamSync-compatible JamMan looper with the SDRUM, the looper must be armed for recording either before playback is initiated in the SDRUM or during playback and before the SDRUM reaches bar 1 (the beginning of the drum pattern). It’s at bar 1 that the SDRUM will tell the slave device to begin recording, but the slave must be armed for recording in advance.

To use the SDRUM with JamMan loopers:

1. With an empty part selected, press the FOOTSWITCH on the SDRUM and teach it a drum pattern by scratching the guitar or using the KICK/SNARE pads.

2. When finished teaching the SDRUM, press the FOOTSWITCH once to set the loop end point. The drum pattern will automatically begin playing in a repeating loop and the PL AY LED will light solid green.

3. Press the FOOTSWITCH on the slave looper to arm it for recording. The looper can be armed at any time while the SDRUM is playing. The looper's REC LED will flash red to indicate it is armed for recording. Recording will begin once the SDRUM makes another pass of the beginning of the drum pattern (the REC LED will light solid red on the slave device when recording begins). Once recording has begun, play the guitar part. The recorded loop must be the same length as the SDRUM's loop or a multiple of it.

4. When finished recording to the slave device, press the slave’s FOOTSWITCH once to set the loop end point. The phrase will automatically begin playing along with the SDRUM's loop and the PLAY LED will light solid green on the looper.

5. Repeat steps 3-4 to record loops for any other loopers connected via JamSync.

6. Hold the FOOTSWITCH on the SDRUM to stop loop playback on all devices.

NOTE: The SDRUM has some capabilities that are not currently supported by any JamSync slave devices:

• Variable Tempo – If a loop is recorded on a JamSync slave, and then the tempo on the SDRUM is subsequently changed, the slave will lose sync with the SDRUM. It's recommended that the tempo be dialed in for a song on the SDRUM before recording to a JamSync slave.

• Multiple Parts – When changing parts on the SDRUM, the JamSync slave will not be aware of the change. So if the slave's loop length is compatible with the new part (e.g., it is an integer multiple of the new SDRUM part's loop length) then the device will stay in sync; but if the slave's loop length is not compatible, it will lose sync with the SDRUM.

NOTE: Some JamSync-compatible loopers support a “Sequential Slave Recording Method” (recording loops to one looper, then immediately to the next, etc.). Note that the SDRUM does not support this functionality.

To play the SDRUM and slave devices:

1. Press the FOOTSWITCH on all slave devices to arm them for playback. The green PL AY LED will flash on each.

2. Press the FOOTSWITCH on the SDRUM to start playback. Each slave will start playing in sync with the SDRUM and its LED will light solid green.

3. Hold the FOOTSWITCH on the SDRUM to stop loop playback on all devices.

Using an FS3X Footswitch

An optional DigiTech FS3X Footswitch can be connected to the FS3X IN jack for additional handsfree control of the SDRUM.

A TRS (tip-ring-sleeve) 1/4” cable must be used when connecting the FS3X.

When using a FS3X for control, there are three modes of operation to select from: Live, Table Top, and Direct Part. These modes are accessed by holding one of the FS3X footswitches when making the connection to the SDRUM. The table below describes how to enter each FS3X mode and the functions controlled by each.

Factory Reset

Performing the factory reset will return the SDRUM back to its original factory default settings:

• All 36 songs will be erased.

• The guitar calibration profile will be erased.

• The count-in feature will be disabled.

• CLEAN will be selected as the default drum kit.

To perform a factory reset:

WARNING: Performing the factory reset will irreversibly delete all 36 songs. Once performed, this procedure is irreversible.

1. Unplug the power adapter from the SDRUM.

2. Press and hold the KICK pad, SNARE pad, and ALT (GROOVE/KIT) button, and then plug in the power

adapter.

3. Wait for the LEDs to begin circling the HATS/RIDES encoder, then release the buttons.

4. When the LEDs surrounding the HATS/RIDES encoder begin flashing amber, press the HATS/RIDES

encoder and wait for the factory reset to complete. The HATS/RIDES LEDs will cycle red, then amber, then green during the reset, and once complete, the SDRUM will return to normal operation.

NOTE: If the HATS/RIDES encoder is not pressed, the operation will time out and the factory reset will be cancelled. Pressing any button other than the HATS/RIDES encoder will also cancel the factory reset.
