This symbol indicates explanations about dangerous matters. If users ignore this symbol and handle the device the wrong way, bodily injury and damage to the equipment could result.

Please observe the following safety tips and precautions to ensure hazard-free use of the MRS-4.

About power

Since power consumption of this unit is fairly high, we recommend the use of an AC adapter whenever possible. When powering the unit from the batteries, use only an alkaline type.

AC adapter operation

• Be sure to use only an AC adapter which supplies 9 V DC, 300 mA and is equipped with a "center minus" plug (Zoom AD-0006). The use of an adapter other than the specified type may damage the unit and pose a safety hazard.

• Connect the AC adapter only to an AC outlet that supplies the rated voltage required by the adapter.

• When disconnecting the AC adapter from the AC outlet, always grasp the adapter itself and do not pull at the cable.

• If the unit is not to be used for a long time, disconnect the AC adapter from the outlet.

Battery operation

•

Use four IEC R6 (size AA) batteries (alkaline or manganese).

• The MRS-4 cannot be used for recharging. Pay close attention to the labelling of the battery to make sure you choose the correct type.

• If the MRS-4 is not to be used for an extended period of time, remove the battery from the unit.

• If batteries leakage has occurred, wipe the battery compartment and the battery terminals carefully to remove all remnants of battery fluid.

• While using the unit, the battery compartment cover should be closed.

Environment

Avoid using your MRS-4 in environments where it will be exposed to:

• Extreme temperature

• High humidity or moisture

• Excessive dust or sand

• Excessive vibration or shock

Handling

• Since the MRS-4 is a precision electronic device, avoid applying excessive force to the controls. Do not operate the keys or controls with your foot.

• Take care that no foreign objects (coins or pins etc.) or liquids can enter the unit.

• Be sure to turn the power to all equipment off before making connections.

• Before moving the unit, turn the power off, and disconnect all cables and the AC adapter.

Alterations

Never open the case of the MRS-4 or attempt to modify the product in any way since this can result in damage to the unit.

In Case of Trouble

If there seems to be a defect or a problem with the unit, immediately disconnect the AC adapter or remove the batteries to shut off the power. Then disconnect any other cables connected to the unit.

Usage Precautions

• Electrical interference

For safety considerations, the MRS-4 has been designed to provide maximum protection against the emission of electromagnetic radiation from inside the device, and protection from external interference. However, equipment that is very susceptible to interference or that emits powerful electromagnetic waves should not be placed near the MRS-4, as the possibility of interference cannot be ruled out entirely.

With any type of digital control device, the MRS-4 included, electromagnetic interference can cause malfunctioning and can corrupt or destroy data. Care should be taken to minimize the risk of damage.

• Cleaning

Use a soft, dry cloth to clean the MRS-4. If necessary, slightly moisten the cloth. Do not use abrasive cleanser, wax, or solvents (such as paint thinner or cleaning alcohol), since these may dull the finish or damage the surface.

Please keep this manual at hand for future reference.

Warning

Caution

The MRS-4 provides three types of effects: insert effect, mixdown effect, and send/return effect. These effects have different characteristics, as described below.

■ Insert effect

This effect operates directly after the input mixer. It is used to modify the input signal before it is recorded.

■ Mixdown effect

This effect operates directly before the MASTER faders of the track mixer. It is used to modify the signal mixed from tracks 1 – 4.

■ Send/return effect

This effect is internally connected to the send/return loop of the mixer section. The effect can be adjusted individually for each track by using the send level control. The higher the setting, the stronger the effect.

The MRS-4 has two types of mixers.

■ Input mixer

Serves to adjust the instrument or mic signal input to the MRS-4 and to assign the signal to the desired track.

■ Track mixer

Serves to mix the playback signal of the recorder before sending it to the stereo output jacks. The signal from each of tracks 1 – 4 is sent to the mixer channels 1 – 4 for individual adjustment of EQ, effect send level, panning (left/right playback position), etc. These items are called track parameters.

SmartMedia

To use the MRS-4, a SmartMedia card is required. Before turning the MRS-4 on, insert the card into the front panel slot, as shown in the illustration below.

◆ Caution ◆

●

If the card is inserted upside down or with wrong orientation, it does not go all the way in. Do not try to force the card in, because this will damage the card.

●

Never insert or remove the SmartMedia card while power to the unit is turned on. Otherwise data may be lost.

●

Standard SmartMedia cards (designed for 3.3V) with a capacity from 16 – 128 MB can be used.

●

When wishing to use a SmartMedia card that has been formatted in other equipment such as a computer or digital camera, you must format the card again in the MRS-4, as described on page 53.

Introduction

ZOOM MRS-4

Internal configuration

The MRS-4 is divided internally into the following three sections.

■ Recorder section

The MRS-4 is a 4-track recorder that uses SmartMedia cards for storing data. This allows audio recording/playback on four tracks.

■ Effect section

The audio signal can be processed in various ways by the effect section. The MRS-4 offers an insert effect for the input signal as well as a send/return effect and mixdown effect for use on the recorderd signal.

■ Mixer section

This section is used for mixing the various signals and supplying them to the other sections. There is an input mixer for

assigning the input signal to various tracks, and a track mixer that adjusts level and sound quality for each track before sending the result to the left and right MASTER jacks.

The illustration below shows the signal flow and how the sections fit together.

Now let's take a closer look at each section.

The recorder section of the MRS-4 has four tracks (separate segments for recording audio data). Up to two tracks can be recorded simultaneously, and up to four tracks can be played back simultaneously. Each of the tracks 1 – 4 has eight virtual tracks (called "V-takes"). In each track, one V-take can be selected for recording/playback. For example, you can record guitar solos onto multiple V-takes, and then compare them later to select the best take.

Connections

When a line level signal such as that from a CD player or rhythm machine is connected to the AUX IN [L/MONO]/[R] jacks, it will be output from the MASTER [L]/[R] jacks together with the mixed playback signal from the tracks of the MRS-4. For a stereo device, use both the [L/MONO] and [R] jacks. For a mono device, use only the [L/MONO] jack.

Connect the monitor system or master recorder to the MASTER [L]/[R] jacks.

To power the MRS-4 from an AC outlet, be sure to use only the AC adapter ZOOM AD0006 (available separately). Using another kind of AC adapter may result in damage.

To synchronize operation of the recorder section of the MRS-4 with another MIDI device, connect the [MIDI OUT] connector of the MRS4 to the MIDI IN connector of the other device

To monitor with headphones, plug them into the [PHONES] jack. This jack carries the same signal as the MASTER [L]/[R] jacks

You can record more tracks in the same way.

When recording of tracks 1 – 4 is completed, you can adjust the level, EQ, and panning of each track to create the final stereo mix. This process is called mixdown.

When performing mixdown on the MRS-4, you can either record the completed song on an external master recorder, or on unused V-takes in the MRS-4. The example in this section explains how to record on an external master recorder.

Connect the master recorder and make other preparations as follows.

Connect a master recorder (MD or DAT or similar) to the MASTER [L]/[R] jacks.

The connection principle for an external master recorder is shown below.

The track mixer incorporates a send/return effect with reverb/delay/chorus. The signal flow when

using the send/return effect is as follows.

The intensity of the send/return effect can be adjusted for each track individually by adjusting the send level. Raising the level causes the effect to be more pronounced for that track. This example shows how to select the algorithm for the send/return effect and how to adjust the send level.

For the send/return effect, you can select a reverb, delay, or chorus type algorithm. Each type has one parameter (an element for adjusting the action of the effect) that allows a more finely graded adjustment than the send level. Available algorithms and parameters are listed in the table on page 22 – 23.

Combining multiple tracks (Bounce function)

"Bounce" is a function that mixes the recorded content of several tracks and records them on one or two tracks. This is sometimes also called "ping-pong recording". Even when all 4 tracks are recorded, the MRS-4 allows you to play them back simultaneously and bounce them onto currently unused Vtakes.

For example, after bouncing 4 tracks onto 1 or 2 V-takes, switching the V-takes of the tracks allows you to listen to the bounce target tracks while overdubbing another instrument on the remaining tracks. Instead of using an external master recorder, it is also possible to perform mixdown onto two internal V-takes.

This section describes how to bounce the Vtakes 1 of tracks 1 – 4 onto V-takes 8 of tracks 1 and 2.

Specifying the bounce target V-take

While the main screen is shown, press the [SONG/UTILITY/TUNER] key, and then use the left/right [PARAMETER/VALUE] keys to bring the indication "BOUNCE" onto the display.

Press the [ENTER/YES] key.

Using V-takes

Each track 1 – 4 of the recorder contains eight virtual tracks called "V-takes". For each track, you can select one take, which will be used for recording and playback. For example, you can switch V-takes and record important passages such as vocal or guitar solos several times on the same track. Later you can compare them and select the best Vtake. To switch the V-take for a track, proceed as follows.

While the main screen is shown, press the [TRACK PARAMETER] key.

The track parameter menu appears.

Use the status keys 1 – 4 to select the track you wish to switch.

This section describes how to use manual punch-in/out to re-record a region of a previously recorded track.

Repeatedly press the status key of the track on which you want to punch-in/out, until the key is lit in red.

Raise the fader of the corresponding channel to a suitable position.

While playing the instrument connected to the input, adjust the input sensitivity.

If necessary, play back the recorder and use the faders of the mixer section to adjust the mix balance of your instrument and the playback of the tracks.

Move to a point several measures earlier than where you want to punch-in, and press the PLAY [

]

key to begin playback.

When the metronome is on and playback is started from a point midway in a song, no precount clicks are heard. Depending on the start position, the metronome sound may start within a beat.

When you come to the punch-in location, press the REC [

] key.

The REC [O] key lights, and track recording begins from that location (punch-in).

When you come to the punch-out location, press the REC [

] once

more.

The REC [O] key goes out, and the unit switches from recording to playback (punch-out).

To stop the recorder, press the STOP [

] key.

The display briefly shows "WAIT".

The length of the "WAIT" interval depends on setting conditions.

To check the newly recorded content, move to the point of step 4, and press the PLAY [

] key.

To redo punch-in/punch-out, repeat steps 4 – 7.

When the results are as desired, press the status key for that track so that the key lights in green.

Auto punch-in/out is a function that lets you specify beforehand the region to be rerecorded. Punch-in will occur automatically when you reach the starting location (In point), and punch-out will occur automatically when you reach the ending location (Out point).

The procedure is as follows.

Setting the In/Out points

Repeatedly press the status key of the track on which you want to punch-in/out, until the key is lit in red.

Raise the fader of the corresponding channel to a suitable position.

While playing the instrument connected to the input, adjust the input sensitivity.

Move to the point at which you want to punch-in, and press the [AUTO PUNCH IN/OUT] key.

The [AUTO PUNCH IN/OUT] key flashes. This sets the "In point" at which recording will begin.

Carrying out the bounce function

Adjust the level balance, pan, and EQ of tracks 1 – 4.

Press the [BOUNCE] key.

The [BOUNCE] key lights up and the bounce function is activated.

If desired, you can also use the send/return effect and mixdown effect during bounce. (For details, see page 21, 25.)

On the main screen, press the status keys 1/2 for the bounce target tracks 1/2, so that the keys are lit in red.

Make sure that [ON/OFF] keys 1/2 and the [METRONOME] key are out.

Return to the beginning of the song, and then press the PLAY [

] key while holding down the REC [

] key.

The mixed signal of tracks 1 – 4 is routed through the MASTER fader and recorded on the bounce target (V-takes 8 of tracks 1 and

2). The level meter L/R indication allows checking the level.

• When bouncing in stereo, the odd-numbered track of the bounce destination is automatically recorded as the left channel and the even-numbered track as the right channel.

•By setting the ON/OFF keys 1/2 to ON, it is possible to add the input signal from inputs 1/2 to the bounced signal.

• The input signal from the AUX IN jacks and from the internal metronome is not recorded.

When recording is completed, stop the recorder.

The display briefly shows "WAIT".

The length of the "WAIT" interval depends on setting conditions.

10.

On the target track, select the Vtakes that were used as bounce targets, return to the beginning of the song, and check the recording.

At this time, the status keys of tracks 3/4 should be out, so that the tracks are muted.

To redo the bounce process, repeat steps 5 – 9.

When playing back bounce target V-takes, the parameters previously set for that track will be active. Panning, EQ, and effect depth therefore may be different from the actual recording. To accurately monitor the content of the bounce target, reset the track parameter settings.

11.

When the results are as desired, press the [BOUNCE] key so that the key goes out.

The bounce function is turned off.

Re-recording only a specified region (Punchin/out function)

Punch-in/out is a function that lets you rerecord just a specified region of a previously recorded track. The action of switching a track that is in play mode to record mode is called "punch-in", and the action of switching back from recording to playback is called "punch-out".

The MRS-4 provides two ways to do this. You can use the panel keys to punch-in/out manually ("manual punch-in/out"), or cause punch-in/out to occur automatically at previously specified points ("auto punchin/out").

Assigning two inputs to a track

In the "Basic Operation" section, we learned how to record the signal from one input on one track. By using the input mixer, it is also possible to combine the signal from two inputs onto one track, or to record it on two tracks separately. The procedure is described below.

Connect the instrument or microphone to be recorded to the [INPUT 1]/[INPUT 2] jacks.

Set [ON/OFF] keys 1/2 to ON.

While listening to the sound, operate the [INPUT LEVEL] controls 1/2 to adjust the input sensitivity.

The input level for each input can be checked separately on the display.

Repeatedly press the status key for the track on which you want to record, until the key is lit in red. The track is now in the recording standby condition.

The maximum number of tracks you can record to simultaneously is two. Only the combination of tracks 1/2 or tracks 3/4 is allowed.

The signal flow from the input mixer to the tracks depends on the track selection and the status of the [ON/OFF] keys 1/2, as shown in the illustrations.

Use the [PARAMETER/VALUE] keys to adjust the parameter.

The left/right [PARAMETER/VALUE] keys serve for selecting the parameter and the up/down [PARAMETER/VALUE] keys for setting the value.

• When wishing to use the send/return effect, press the [SEND/RETURN] key to set it to ON, and then select the algorithm and parameter (

➝ p. 21).

• When a signal is sent from the input mixer to the send/return effect, only the signal output from the MASTER [L]/[R] jacks reflects the effect. The effect has no influence on the signal recorded on the track.

When preparations are complete, play the instrument and perform mixdown.

The input 1/2 signal is mixed to the track 1 – 4 signal and sent to the master recorder. It is also possible to apply the mixdown effect to the mixed signal.

When bouncing the signal onto internal V-takes, the input signal can also be mixed in as described above.

Linking two tracks (stereo link function)

This function allows you to link two tracks in the track mixer, so that their parameters (except the V-take selection) are adjusted in sync. This is convenient to control stereo material that was recorded on two tracks.

While the main screen is shown, press the [TRACK PARAMETER] key.

The track parameter menu appears.

Use the status keys 1 – 4 to select one of the two tracks you want to link.

Use the left/right [PARAMETER/ VALUE] keys to call up the STL (stereo link) parameter.

Use the up/down [PARAMETER/ VALUE] keys to set the STL parameter to ON.

When status key 1 or 2 was pressed in step 2, tracks 1 and 2 are linked. When status key 3 or 4 was pressed, tracks 3 and 4 are linked. When two tracks are linked, the following applies.

●

When the stereo link is activated, the PAN parameter is set to 0 for both tracks. The values for all other track parameters (except V-take selection) are copied from the odd-numbered track to the evennumbered track.

●

When the parameter in one track is changed, the parameter of the other track also changes accordingly (except V-take selection).

●

When the fader for the odd-numbered track is operated, the level in both tracks changes. (The fader of the even-numbered track is inactive.)

●

The PAN parameter operates as a BALANCE parameter that adjusts the level balance between the two (left and right) channels.

To cancel the stereo link, set the STL parameter to OFF.

When no recording track is selected

• When when the insert effect is used, the basic signal flow for inputs 1/2 remains same.

• Depending on the selected insert effect algorithm, the level at input 1 and 2 may be watched simultaneously for operation in both channels, or inputs 1 and 2 may operate independently.

Adding the input signal to the mixdown

When performing mixdown, the input mixer can be used to add the signal from inputs 1/2.

Connect the master recorder to the MASTER [L]/[R] jacks and make the necessary preparations for mixdown (

➜

p. 18).

Connect the instrument or microphone to add to the mix to the [INPUT 1]/[INPUT 2] jacks.

Set the [ON/OFF] keys 1/2 to ON.

Functions available with MIDI

MIDI (Musical Instrument Digital Interface) is a standard that allows various types of messages such as playing and timing information to be exchanged between devices such as electronic musical instruments and computers.

The MRS-4 supports MIDI, and can transfer the following messages to another MIDIcompatible device via the [MIDI OUT] connector located on the rear panel.

●

Timing clock

Timing information used for synchronization of MIDI devices such as rhythm machines and MIDI sequencers. The internal metronome of the MRS-4 divides a quarter note into 24 ticks and sends this as a timing signal.

●

Song position pointer

A message that specifies the current location in measures and beats, counted from the start of the song. The measure and beat count uses the time signature of the internal metronome as a reference.

●

Start/Stop/Continue

Message that controls transport movements of a device.

By sending the above kinds of messages for example to a rhythm machine or MIDI sequencer, the external device can be synchronized to the song of the MRS-4.

The MRS-4 supplies the above MIDI messages at all times. When not wishing to receive these at an external device, disconnect the MIDI cable.

Synchronizing an external device to the MRS-4

You can synchronize operation of an external MIDI device such as a rhythm machine or MIDI sequencer to the song of the MRS-4.

Connect the MIDI IN connector of the other device to the [MIDI OUT] connector of the MRS-4. (For information on connections, see page 8.)

Set the rhythm machine, MIDI sequencer, or other MIDI device to synchronize with an external MIDI clock.

For details, refer to the documentation of the rhythm machine, MIDI sequencer, or other MIDI device.

Set the metronome tempo and time signature setting of the MRS4 as required for the music piece that you want to synchronize.

When synchronizing an external device to the MRS-4, the measure/beat position information is referenced to the internal metronome of the MRS-4. Therefore a matching setting should be used. (For information on how to make metronome settings, see page 50.)

Return to the start position of the MRS-4 song, and start playback.

When the precount is finished, a start message is sent to the external device, and the device operates in sync with the MRS-4. When the song is stopped at the MRS-4, the external device is also stopped.

When the song is stopped midway, a song position pointer indicating the current position is sent. Consequently, provided that the metronome time signature setting matches, the external device will start playback from the same position even if playback of the song at the MRS-4 is started midway.

Using the AUX IN jacks to save tracks

AUX IN is an input that accepts an external signal which is then mixed with the internal signal of the MRS-4 and output as is at the MASTER [L]/[R] jacks. This can serve several purposes. For example, during track recording or overdubbing, you could connect a rhythm machine synchronized to the MRS-4 to the [AUX IN] jacks and reproduce this with the overall sound. This eliminates the need to record the rhythm machine on its own track, thereby freeing up tracks for other purposes. The procedure for doing this is described below.

Track recording/overdubbing

During track recording/overdubbing, connect the output of a rhythm machine to the [AUX IN] jacks. Synchronize playback of the rhythm machine to operation of the MRS-4, use tracks 1 – 4 for recording parts such as guitar, bass, vocal etc. while listening to the sound of the rhythm machine.

The output at the MASTER [L]/[R] jacks allows you to monitor the sound from the instrument currently being recorded, the playback sound of MRS-4 tracks, and the rhythm machine sound input via the [AUX IN] jacks. However, the rhythm machine sound cannot be recorded on a track.

Bounce/mixdown

During bounce/mixdown, change the rhythm machine connection over to the [INPUT 1]/[INPUT 2] jacks. If you synchronize operation of the MRS-4 and the rhythm machine, you can mix the rhythm machine sound with the playback sound from tracks 1 – 4 for bounce/mixdown. The rhythm machine mix ratio can be adjusted with the [INPUT LEVEL] control 1/2.

You can also apply the send/return effect and mixdown effect to the rhythm machine sound (

➝ p. 21, 25).

ZOOM MRS-4

Specifications

MRS-4 file configuration

The MRS-4 stores the following file types on the SmartMedia card.

●

xx-yz.aud

This file contains the audio data recorded on a V-take. The number of such files on the SmartMedia card corresponds to the number of recorded V-takes. When a song is deleted, the V-take files belonging to that song are deleted.

xx = song number (0 – 14) y = track number (0 – 3) z = V-take number (0 – 7)

●

Songno.mr4

This file contains information about the currently used song number, global parameter values, and mount information for the MRS-4 Card Manager (see below).

●

UtyprmXX.mr4

This file contains the default settings for all items and song parameters. The number of such files on the SmartMedia card corresponds to the number of songs that were created. When a song is deleted, this file is also deleted.

xx = song number (0 – 14)

File compatibility with PS-02

Setting file

Setting files for the ZOOM PS-02 and the MRS-4 are not compatible. If a PS-02 SmartMedia card is inserted in the MRS-4, the various setting files are disregarded.

Audio file

Audio files for the ZOOM PS-02 and the MRS-4 are theoretically not compatible. If a PS-02 SmartMedia card is inserted in the MRS-4, some audio files may be readable, but playback pitch will be different from the original. Depending on the settings, some audio files may not be readable at all.

Zoom Corporation assumes no responsibility for any consequences of using PS-02 SmartMedia in the MRS-4.

MRS-4 Card Manager Software

If you have Internet access, you can download the MRS-4 Card Manager software from the Zoom Corporation web site free of charge (Windows/Macintosh versions). It allows a computer equipped with a SmartMedia card reader to manage MRS-4 data. The software provides the following functions.

●

Convert MRS-4 audio data into WAV files

●

Convert WAV/AIFF format audio files into MRS-4 audio data

●

Back up the SmartMedia card contents onto the hard disk of the computer

Recording times are approximate. Actual times may be somewhat shorter, depending on setting conditions.

NOTE

ZOOM MRS-4

The recorded sound is distorted

• Check whether the input sensitivity setting ([INPUT LEVEL] controls 1/2) was appropriate.

•Lower the track faders or MASTER fader so that the 0 (dB) dot of the level meter does not light.

• If the EQ gain of the track mixer is set extremely high, the sound may be audibly distorted even if the fader is lowered. Set the EQ to an appropriate value.

Insert effect does not operate

• Make sure that the [SEND/RETURN] key and [MIXDOWN] key are flashing or lit in red.

• Check that the limiter and compressor settings are not too low for the input level.

Send/return effect does not operate

• Make sure that the [SEND/RETURN] key is flashing or lit in green. If the key is not lit, press the key to make it light in green.

•Make sure that the SEND parameter for each mixer track is on and that the SLVL parameter is set to a suitable value.

Mixdown effect does not operate

• Make sure that the [SEND/RETURN] key is flashing or lit in green. If the key is not lit, press the key to make it light in green.

Cannot synchronize with external MIDI device

• Make sure that the [MIDI OUT] connector on the MRS-4 is properly connected to the MIDI IN connector on the external MIDI device with a MIDI cable.

• Make sure that the external MIDI device is set up to receive a timing clock signal for synchronized operation.

• Make sure that the external MIDI device is set to the playback condition.

• Make sure that the metronome tempo and time signature settings match the song on the external MIDI device.

Cannot use tuner function

• The tuner cannot be used during song playback. Stop the song before using the tuner.

• Make sure that the [ON/OFF] key of the respective input is on, and the [INPUT LEVEL] control 1/2 is raised.

One of the following messages appears on the display

• PLYSTOP

This operation cannot be carried out during recorder operation. Stop the recorder first.

Problems with MIDI

Problems with effects

No sound, or very low volume

• Check the connections to your monitor system, and the volume of your monitor system.

• Make sure that the status keys 1 – 4 are lit in green. If a key is not lit, press the key to make it light in green.

• Make sure that the track faders 1 – 4 and the MASTER fader are raised.

• Make sure that a SmartMedia card is inserted in the card slot.

Operating the fader does not affect the volume

• On channels for which stereo link is turned on, the fader of the even-numbered channel will have no effect. Either turn stereo link off (

➝ p. 39), or operate the

fader of the odd-numbered channel.

Recorder stops midway during play

•When performing playback with a status key lit in red, a temporary file is created internally by the MRS-4. If the remaining capacity of the SmartMedia card then becomes low, playback is stopped midway through the song. In such a case, press the status key so that it goes out or is lit in green.

Noise occurs during mixdown

• Make sure that the [ON/OFF] keys 1/2 are out.

• Check whether the mixdown effect is set to an extreme setting.

Input signal is not heard, or very low volume

• Make sure that the [ON/OFF] keys 1/2 are lit.

• Make sure that the [INPUT LEVEL] controls 1/2 are turned up.

Can't record on a track

• Make sure that the status key of the track selected for recording is lit in red.

• Recording is not possible if the song is protected. Either turn protect off (

➝ p. 49), or use another song.

• Make sure that a SmartMedia card is inserted in the card slot.

• The signal from the [AUX IN] jacks cannot be recorded on a track. Connect the sound source for recording to the [INPUT 1]/[INPUT 2] jacks.

Cannot perform bounce

• Make sure that the [BOUNCE] key is on.

• Make sure that the status key of the track selected as bounce destination is lit in red.

• Make sure that the track faders 1 – 4 and the MASTER fader are raised.
