About the AN200 Editor

The AN200 Editor is a full-featured editing software program for the AN200 Desktop Control Synthesizer, providing an exceptionally simple, convenient and intuitive way to edit and control all of the AN200 parameters. Virtual "knobs," "buttons" and a special "LCD display" let you change parameters just as if you were operating an actual synthesizer control panel!

The AN200 Editor lets you save your edits as an original User pattern and store up to 128 User. Naturally, you can save the data to ﬂoppy disks or your hard disk drive as AN200 Files. The AN200 Editor also features a convenient, easy-to-use AN200 Librarian that lets you organize your User patterns.

For general instructions and explanations on how to use the AN200 Editor, see Setting and Changing Parameter Values and Toolbar. For information on speciﬁc, commonly used operations, see Operations.

Operations

Selecting an AN200 Pattern

Selecting an AN200 pattern is the important ﬁrst step in editing. You can select a pattern from the Preset 1, Preset 2, or User banks (each of which contains 128 patterns). Once you’ve edited a pattern you can store it to the User bank as your original pattern and save it to a ﬂoppy disk/hard disk drive with other patterns as an AN200 File.

AN200 patterns can be selected from either the Edit Panel window or the main control panel window.

•Make sure to store your edits to a pattern before selecting another pattern. If you’ve edited the AN200 Editor parameters and then select a different pattern, all your edited parameters will be initialized to the default values of the newly selected pattern.

z Select “AN200 Pattern List.”

Click the PATTERN button at the bottom right of the main control panel.

You can also quickly call up this dialog box by clicking any inactive part of the window pressing control key and clicking "AN200 Pattern List" in the pop-up menu. Or, you can click "Edit" on the menu bar, then select "AN200 Pattern List."

x Select the desired pattern.

Click on the desired pattern, then close the dialog box (click the close button) to return to the main control panel window. (You can also do this by clicking anywhere on the main control panel.)

Operations / Editing an AN200 Pattern

Editing an AN200 Pattern

z Select the desired pattern.

Refer to Selecting an AN200 Pattern.

x Edit the pattern parameters as desired from the main control panel.

The main window of the AN200 Editor provides a "virtual" control panel with knobs and buttons, and lets you edit the patterns much as you would if you were operating an actual hardware synthesizer.

c Store the edited settings as a User pattern, then save it with other edited patterns as an AN200 File.

Use the Store operation to store your newly edited pattern. Then use the Save operation to save that edited pattern with other User patterns to an AN200 File.

Both the Store and Save operations are necessary to ensure that your pattern is saved properly. Failing to do so would be roughly similar to writing a letter but not putting it in an envelope and sending it. Make sure to execute both operations when you wish to keep a pattern you’ve edited.

Operations / Initializing an AN200 Pattern to the Default Settings

Initializing an AN200 Pattern to the Default Settings

This function allows you to reset all the parameters of the selected pattern to the factory "initial pattern" default values. This gives you a "blank slate" from which you can create your own pattern.

Keep in mind that this operation automatically erases all the settings of the selected pattern. If you wish to save the pattern for future recall, use the Store and Save functions.

z Select “AN200 Pattern List.”

Click the PATTERN button at the bottom right of the main control panel.

x Select the User bank and the desired pattern to be initialized.

Click on the User bank button, then click on the desired pattern.

c Initialize the pattern.

Click the "Pattern Init" button in the dialog box. The speciﬁed pattern is initialized and automatically selected for editing.

To return to the main control panel window, close the dialog box (click the close button). (You can also do this by clicking anywhere on the main control panel.)

•If you want to initialize all User patterns, then click on the "INIT ALL" button in the AN200 Librarian window.

Operations / Storing an AN200 Pattern

Storing an AN200 Pattern

This operation lets you store your pattern edits as a User pattern.

•To ensure that your new pattern is available for future recall, make sure to also save the pattern (with other patterns) to an AN200 File.

z Select “AN200 Store.”

Click the red STORE button at the bottom right of the main control panel.

You can also quickly call up this dialog box by clicking any inactive part of the window pressing control key and clicking "AN200 Store" in the pop-up menu. Or, click "Edit" on the menu bar, then select "AN200 Store."

x Select the destination pattern.

Click on the desired pattern in the dialog box. Keep in mind that this pattern will be erased and replaced with the newly edited pattern.

c Store the pattern.

Click the "Store" button in the dialog box. The newly edited pattern is stored to the selected location.

•This operation deletes the original pattern data at the destination.

•Keep in mind that this operation stores your pattern data only into the User pattern memory of the AN200 Editor and sends the current pattern’s bulk data to the AN200. The current pattern bulk data will be lost if you select another pattern on the panel of the AN200. If you want to select a pattern on the panel of the AN200, you should ﬁrst transmit the User Pattern. (Refer to Transmit AN200 Bulk Dump Data.) There is no need to transmit AN200 Bulk Dump Data if you select a pattern in the Pattern List of the AN200 Editor, since the current pattern bulk data is sent with that operation.

Operations / Saving data to an AN200 File

Saving data to an AN200 File

Once you’ve edited an AN pattern and pattern to your satisfaction you can save it to an AN200 File. Each AN200 File can contain up to 128 patterns, and these can be called up at any time with the Open function. (Also see Calling Up Data from an AN200 File.)

Additional AN200 ﬁles (each with 128 User patterns) can be saved to ﬂoppy disks or your hard disk drive --- giving you unlimited storage for your original patterns. For organizing the patterns in the AN200 Files, use the convenient AN200 Librarian function.

z Select “Save AN200 File.”

Click "File" on the menu bar, then select "Save AN200 File".

•"Save AN200 File" can also be selected from the toolbar.

x Select the desired folder, type in the ﬁle name, and click “Save.”

Calling Up data from an AN200 File (Open)

Once you’ve saved a set of User patterns and to one or more AN200 Files (see Saving Patterns), you can instantly call up the desired patterns with this command.

To create a new AN200 File, use the New command.

z Select “Open AN200 File.”

Click "File" on the menu bar, then select "Open AN200 File." Open AN200 File is also available on the toolbar.

xSelect the desired folder and ﬁle name, then click “Open.”

•Keep in mind that this operation loads the User pattern data only into the User pattern memory of the AN200 Editor. After opening a ﬁle, if you want to play these Patterns on the AN200 separate from the AN200 Editor, you should transmit the User pattern data. (Refer to Transmit AN Bulk Dump Data.) There is no need to transmit AN200 Bulk Dump Data if you select a pattern in the Pattern List of the AN200 Editor, since the current pattern bulk data is sent with that operation.

Parameters

Most of the AN200 Editor parameters for editing the AN200 patterns are contained in the virtual "main control panel" screen. From this main panel, you can also jump to other windows for controlling additional AN200 functions (such as the Control Matrix, Free EG, and Step Sequencer).

AN200 Editor Main Window

This is the main control panel for the AN200 Editor, and is comprised of the virtual "panel" controls, the toolbar (at the top), and the virtual "LCD display" at the bottom. The master menu (which includes AN200 Pattern List, Store, and the Display Option) can also be selected from the main screen by clicking pressing control key any inactive part of the front panel.

To jump to explanations for the desired parameter, click on the appropriate block in the illustration below.

• Main Screen

•Master Menu

Click while pressing control key in an inactive area to call up the master menu.

Parameters / AN200 Editor Main Window

•Toolbar

The toolbar gives you quick access to some important functions and controls. These buttons let you easily execute the desired function without having to select a menu or leave the AN200 Editor window.

Open AN200 File

This is the same as the corresponding command in the File menu. It lets you select and open an existing AN200 File. (See File Menus, Open AN200 File.)

Save AN200 File

This is the same as the corresponding command in the File menu. It lets you save the current AN200 Editor settings as a parameter ﬁle for future recall. (See File Menus, Save AN200 File.)

AN200 Editor Setup

This is the same as the corresponding command in the Setup menu. It lets you make various important settings for conﬁguring the AN200 Editor with the AN200. (See Setup Menus, AN200 Editor Setup.)

Setup AN200 Display Option

This convenient feature lets you change the display of the main control panel to indicate the current status of certain signal routings within the AN200. (See Setup Menus, AN200 Display Option.)

Transmit AN200 Bulk Dump Data

This is the same as the corresponding command in the Setup menu. It lets you transmit the current AN200 Editor settings as MIDI data to the AN200. (See Setup Menus, Transmit AN200 Bulk Dump Data.)

Receive AN200 Bulk Dump Data

This is the same as the corresponding command in the Setup menu. It lets you receive the pattern from a connected AN200. (See Setup Menus, Receive AN200 Bulk Dump Data.)

Parameters / AN200 Editor Main Window

•LCD Display

This virtual "LCD" functions just like the display on an actual synthesizer's front panel.

Indicates the current pattern's bank/number as well as its category and name.

Full name of the currently selected parameter.

Indicates the currently selected parameter's value or setting. By clicking on this third line, you can also directly change the value by typing it on the computer keyboard. (See Computer Keyboard.)

• PATTERN Button

Pressing the PATTERN button calls up the AN200 Pattern List dialog box, allowing you to select the desired pattern bank and pattern. It also allows you to reorganize the patterns of a selected bank, as well as initialize a pattern --- in other words, this resets all parameters to their normal values, giving you a "blank slate" pattern to work with.

To select a bank, click on the desired bank button: Preset 1, Preset 2, or User. Each bank contains 128 patterns. To select a pattern, click on the desired pattern in the combo box. For a complete list of available patterns, see the Pattern List in the AN200 Owner's Manual.

•Each pattern name is preceded by a two-letter category abbreviation that indicates the general instrument group to which the pattern belongs. For example, "Ld" indicates "lead," "Ba" indicates "bass," "Pd" indicates "pad," and so on.

Parameters / AN200 Editor Main Window

•STORE Button

Pressing the STORE button calls up the AN200 Store dialog box, allowing you to store the desired pattern to the User bank. It also lets you enter a name and category abbreviation for the pattern.

To name the pattern, click on the Pattern Name box, and type in the desired name. To specify a category, click the Category combo box, and click the desired category abbreviation. (The "0: ---" setting indicates no category.) To store the newly named pattern, click "Store." For a complete list of available patterns and descriptions of the category abbreviations, see the Pattern List in the AN200 Owner's Manual.

Parameters / AN200 Editor Main Window

■Setting and Changing Parameter Values ...................

•For panel knobs:

Click on the knob and drag horizontally or vertically as desired. Dragging to the left or down decreases the value, and dragging right or up increases it. The knob "rotates" as you drag it, and the parameter value (shown just above each knob) changes accordingly. Any parameter changes are output as MIDI data, both to the AN200 and the XGworks sequencer.

Operation of the knobs can also be set so that moving the mouse in a circular direction -- - as if you were actually rotating the knob --- changes the parameter value. (See Parameter Knob Operation.)

•The panel knob operation can be changed to let you "rotate" the knob, instead of moving it horizontally or vertically. (See the Others tab in AN200 Editor Setup.)

•For buttons:

Simply click on the desired button to turn on/off or to select the appropriate setting. On/ off buttons (such as UNISON) have virtual "lamps" that light when the function is on.

•Combo boxes

For combo boxes (such as Control Source in the Control Matrix Parameter tab), click the down arrow to expand the box, then highlight the desired setting.

•DATA DEC (Decrease) and INC (Increase) buttons

Click on the desired parameter, then click either of these buttons to decrease the value/ setting (DEC) or increase it (INC). In some cases (e.g., VCO 1 WAVE), these buttons can be used to select values/settings that are not otherwise available.

Parameters / AN200 Editor Main Window

•Computer keyboard

All of the value parameters in the main control panel can be directly changed by typing in the appropriate numbers from the computer keyboard. Click on the desired parameter, then click the third (bottom) line in the virtual LCD and type in the desired value. Press [enter] to enter the value.

A few parameters (such as Unison Detune and LFO 1 Delay in the Detail Parameters tab) can be directly changed by clicking on the desired parameter, then typing in the desired value and pressing [ENTER].

•Computer keyboard shortcuts:

• Moving around the panel

Pressing the arrow keys by themselves lets you select parameters by moving around the panel in the respective direction (up, down, left, right).

• Rapidly adjusting values

You can also use the arrow keys to adjust the parameter values. Select a parameter then simultaneously hold down [shift] on the computer keyboard and press or hold one of the arrow keys. The up or right keys increase the value while the down or left keys decrease it. Holding down [shift] and the appropriate arrow key rapidly increases or decreases the value.

The Page Up and Page Down keys on the computer keyboard can also be used. Press Page Up to increase the value, and Page Down to decrease it. Hold down the appropriate button to rapidly increase or decrease the value.

•Value charts

A few parameters (such as VCF Velocity) have pop-up "value charts," from which you can select the desired value. Simply click on the parameter's button, highlight the desired value, then click on the value.

Parameters / AN200 Editor Main Window

•Initialize

If you need to initialize a speciﬁc parameter to its default value, you can quickly call up a pop-up menu for this by clicking pressing control key on the appropriate parameter control in the display.

For example, if you've changed the LFO 1 Speed setting and want to restore the parameter to its original value, move the cursor to the LFO 1 SPEED knob and click pressing control key.

Click on "Init" to restore the original setting or value of the parameter.

"Init" will be ghosted and unavailable if no edits have been made to the selected parameter. Initialize is completely independent for each parameter.

■ AN200 Parameters .......................................................

The various parameters are arranged in "blocks" according to their general functions. These correspond to the basic modules of sound generation or control in the AN200.

PEG (Pitch EG) Parameter Block

The PEG parameters determine how the pitch of the pattern changes over time. This lets you produce subtle or pronounced pitch changes as a note is played.

The PEG can also be used as a control source (in PWM Source, Sync Pitch Control Source, FM Source, etc.), giving you even greater editing ﬂexibility.

Parameters / AN200 Editor Main Window

• ATTACK (PEG Attack Time)

Range: 0 ... 127

This determines the Attack Time of the PEG, or how long it takes for the pitch to change, according to the PEG Depth setting. This parameter has no effect unless the DEPTH parameter is set to an appropriate value (except when the PEG is used as a control source — for example, in PWM Source, etc.).

• DECAY (PEG Decay Time)

Range: 0 ... 127

This determines the Decay Time of the PEG, or how long it takes for the pitch to return to normal. This parameter has no effect unless the DEPTH parameter is set to an appropriate value (except when the PEG is used as a control source — for example, in PWM Source, etc.).

•When the Decay Time is set to the maximum value of 127, the pitch (as set in PEG Depth) is held indeﬁnitely without changing.

•DEPTH (PEG Depth) Range: -64 ... +63

This determines the depth of the pitch change for the PEG (in semitones). This can be set independently for either the VCO 1 or VCO 2, or both (with the PEG Switch parameter). This must be set to an appropriate value for the PEG to have an effect on the sound.

• PEG Switch – VCO 1/ VCO 2

Settings: VCO 1, VCO 2, Both

This switch determines which VCO will be affected by the PEG Depth parameter. When this is set to "Both," the VCO 1 and VCO 2 will be affected together (both lamps light).

OCT (Octave Shift)

Range: -2 ... +2

This determines the octave setting of the selected pattern. The octave setting is also indicated by the lamps.

CTRL MATRIX (Control Matrix)

The Control Matrix is a highly ﬂexible, complex function that lets you use up to 15 different MIDI controllers to control 15 separate AN200 parameters, in real time. The source controllers can be a modulation wheel, data entry slider, foot controller, key velocity, key scaling, or any of the controllers in the MIDI speciﬁcation. These can be used to control any of 46 different destination parameters, such as VCF Cutoff, Resonance, FEG Depth, and a wide variety of others.

This gives you the freedom to conﬁgure a completely different set of sources and destination parameters for each pattern. You can, for example, conﬁgure the AN200 to use After Touch to apply vibrato, or the Modulation Wheel to change the resonance while you play, determine the range for both Pitch Bend up and down, and much more.

For information on the Control Matrix settings, see the Ctrl Matrix Parameters tab.

• DETAIL Page (Control Matrix Parameters)

Parameters / AN200 Editor Main Window

FREE EG

The 4-track Free EG lets you record complex control movements, in order to "hand draw" ﬁlter, resonance, LFO and many other available parameters over time---and have them play back automatically by simply playing a pattern. A variety of drawing and editing tools are available for creating unique, continuous parameter changes that would be impossible to achieve with conventional EGs.

Up to four different parameters can be controlled independently, each recorded into its own Free EG track. Ideal for those times when you wish you had an extra couple of pairs of hands, the Free EG lets you build up an incredibly complex, completely unique pattern.

The display windows (1 - 4) indicate the parameters controlled by each Free EG track.

• DETAIL Page (Free EG Parameters)

STEP SEQ. (Step Sequencer) Block

The Step Sequencer block features four basic controls for the Step Sequencer --- a powerful functions that let you trigger complex Sequences in real time, at the press of a key. For more information, see the Step Sequencer DETAIL Page.

•DETAIL Page (Step Sequencer Parameters)

•TEMPO

Range: 20.0 - 300.0 bpm (beats per minute)

This determines the speed of the Step Sequencer. If you want the clock of an external MIDI sequencer or drum machine to control the tempo of the AN200's Step Sequencer, set the Tempo to "MIDI" so that the two devices will play in synchronization with each other.

•When the Free EG LENGTH is set so that the Free EG synchronizes with Tempo, this Tempo setting affects the speed of the Free EG.

•[PLAY]/[STOP] buttons

Click the [PLAY] button to start the Sequence. The Sequence repeats (loops) until you click the [STOP] button to stop it.

Parameters / AN200 Editor Main Window

LFO Parameter Blocks

The LFO parameters allow you to create a wide variety of modulation effects, using a low frequency signal to regularly change the pitch, volume or timbre of the pattern. The LFO can be used to make the sound warmer and more natural, or can be used to produce wild special effects.

LFO 1 and LFO 2 can also be used as control sources (in PWM Source, Sync Pitch Control Source, FM Source, etc.), giving you even greater editing ﬂexibility.

•Depending on the setting of the selected pattern's Assign Group parameter, the LFO 1 and LFO 2 blocks in the display may be different, with different sets of parameters. All LFO parameters below are available on either LFO 1 or LFO 2; however, some parameters will only be available on one of the LFO blocks, while the other block will have a limited parameter set.

•LFO 1 / LFO 2 DETAIL Page

•LFO 1 / LFO 2 WAVE Settings:

Sine, Sine Ofst1 (Offset 1), Sine Ofst2, Sine180 Ofst1, Sine180 Ofst2

Triangle, Triangle Ofst1, Triangle Ofst2, Triangle180 Ofst1, Triangle180 Ofst2

Square, Square Ofst2, Square180 Ofst2

Saw Down, Saw Down Ofst2, Saw Up, Saw Up Ofst2

S/H (Sample & Hold), S/H Ofst2, S/H2, S/H2 Ofst2

•Parameter settings in italics above can only be selected by using the DATA DEC/INC buttons, or by holding [shift] on the computer keyboard and using the cursor keys.

This determines the type of wave for LFO 1 or LFO 2. (The same settings are available for both.) The wave set here determines the characteristics of the modulation applied to the VCO (vibrato), VCF (wah) and VCA (tremolo).

• LFO 1 / LFO 2 SPEED

Range: 1 ... 256

This determines the speed of LFO 1 or LFO 2. (This parameter is the same for both.) Higher values result in a faster LFO modulation. This is a global control in that it affects all modulation destinations (VCO 1/2, VCA, VCF) equally.

•LFO 1 / LFO 2 VCO1

(LFO 1 / LFO 2 to VCO 1 – Oscillator 1 Pitch Modulation Depth)

•LFO 1 / LFO 2 VCO2

(LFO 1 / LFO 2 to VCO 2 – Oscillator 2 Pitch Modulation Depth)

Range: -127 ... +127

This determines the degree to which the LFO 1 or LFO 2 affects the selected oscillator's pitch. This produces a vibrato effect, or a quavering, vibrating sound in the pattern, by regularly modulating the pitch. Higher values result in a stronger, more pronounced vibrato sound.

Parameters / AN200 Editor Main Window

•LFO 1 / LFO 2 VCA

(LFO 1 / LFO 2 to VCA – Amplitude Modulation Depth)

Range: -64 ... +63

This determines the depth of the amplitude modulation of the VCA by LFO 1 or LFO 2. Amplitude Modulation adds a cyclical change to the volume level to create a tremolo effect. Higher values (in the positive range) widen the range of the volume change. Negative values reverse the phase of the LFO by 180 degrees.

• LFO 1 / LFO 2 VCF (LFO 1 / LFO 2 to VCF – Filter Modulation Depth) Range: -64 ... +63

This determines the depth of the ﬁlter modulation of the VCF by LFO 1 or LFO 2. Filter Modulation adds a cyclical change to the ﬁlter cutoff frequency to create a wah effect. Higher values (in the positive range) widen the range of the cutoff frequency change. Negative values reverse the phase of the LFO by 180 degrees.

VCF / FEG Parameter Block

VCF Parameters

The VCF is a ﬁlter that allows a speciﬁc range of frequencies to pass, while muting all others. Movement of the ﬁlter through various frequencies as well as the use of Resonance allows you to create exceptionally dynamic, dramatic changes in the sound. The VCF can be controlled by the ﬁlter EG (FEG) parameters, allowing you to have the timbre of the sound change automatically over time.

• VELOCITY (FEG Velocity Sensitivity)

Range: -64 ... +63

This determines how the ﬁlter EG responds to key velocity. For positive values, playing the keys with greater strength results in a wider, more dynamic ﬁlter EG (greater ﬁlter changes). For negative values, the relationship is inverse: a softer key touch results in a wider, more dynamic ﬁlter EG. A setting of "0" results in no change of the ﬁlter by playing strength.

To set this, click the VELOCITY button and highlight the desired value in the pop-up chart. When a value other than "0" is set, the VELOCITY lamp lights.

Parameters / AN200 Editor Main Window

• HPF (HPF Cutoff)

Range: 0 ... 127

This determines the cutoff frequency of the High Pass Filter (-6 dB/Oct). Frequencies above the setting are passed while those below are cut off. Higher values increase the HPF Cutoff frequency, resulting in a brighter sound.

To set this, click the HPF button and highlight the desired value in the pop-up chart. When a value other than "0" is set, the HPF lamp lights.

•This High Pass Filter is applied to the signal after the mixer, and is different than the one available in the VCF Type parameter.

•TYPE (VCF Filter Type)

Settings: LPF24, LPF18, LPF12, BPF, HPF12, BEF

• When "LPF18" is selected, both the LPF24 and LPF12 lamps light together.

This determines the type of ﬁlter used by the VCF. The VCF passes only a speciﬁed range of frequencies while cutting off the rest, to give you versatile control over the timbre. The six ﬁlter types are described below.

LPF24, LPF18, LPF12

The Low Pass Filter passes only those frequencies below the speciﬁed cutoff point. Cutoff curves of 24dB/octave (LPF24), 18dB/octave (LPF18) and 12dB/octave (LPF12) can be selected.

Parameters / AN200 Editor Main Window

BPF

The Band Pass Filter passes only those frequencies in the speciﬁed range, with a cutoff curve of 12dB/octave.

HPF12

The High Pass Filter passes only those frequencies above the speciﬁed cutoff point, with a cutoff curve of 12dB/octave.

BEF

The Band Eliminate Filter passes only those frequencies outside the speciﬁed frequency range. The Resonance setting (below) determines the eliminated range.

•The ﬁlters listed above apply to the signal output from the HPF located between the Mixer and VCA. For more information about the signal path, see AN200 Display Option.

Parameters / AN200 Editor Main Window

• CUTOFF (VCF Cutoff Frequency)

Range: 0 ... 127

This determines the cutoff frequency of the VCF (ﬁlter). For example, when the ﬁlter type is set to Low Pass Filter, the VCF mutes all frequencies higher than the cutoff point and "passes" the lower frequencies. Lower cutoff values create a deeper, more rounded tone, while higher values create a brighter tone.

• RES. (VCF Resonance)

Range: -12 ... +102

This determines the amount of resonance boost, or emphasis of harmonics near the cutoff frequency. Higher values produce a higher resonant peak (producing sharper high tones), while lower values produce a relatively ﬂat response. A setting of "0" applies no resonance.

Parameters / AN200 Editor Main Window

• KEY TRK (VCF Keyboard Tracking)

Range: -32 ... +63

This determines the degree to which the VCF "tracks" or follows the keyboard. In other words, the higher the notes played on the keyboard, the more the cutoff frequency is raised (or lowered). When Keyboard Tracking is applied, the cutoff range shifts accordingly at every note, with C3 as the base. Positive values will cause higher notes to have a higher cutoff point. Negative values cause higher notes to have a lower cutoff frequency. A value setting of "0" results in no key tracking.

•When this is set to "+32," the change in the cutoff frequency matches (or is directly proportional) with the change in the keyboard notes.

FEG (Filter EG) Parameters

The FEG parameters determine how the timbre of the pattern changes over time. This lets you produce subtle or pronounced ﬁlter effects (such as wah, for example).

The EG DEPTH parameter (in the VCF block) must be set to a proper level for the FEG parameters to have an effect on the sound.

•The FEG can also be used as a control (in PWM Source, Sync Pitch Control Source, FM Source, etc.), giving you even greater sound-shaping ﬂexibility.

•DEPTH (Filter EG Depth)

Range: -128 ... +127

This determines the range of movement of the cutoff frequency. This must be set to a proper level for the FEG parameters (Attack, Decay, Sustain, and Release) to have an effect on the sound. Positive values increase the Filter EG Depth. Negative values reverse the shape of the envelope.
