The Modulation controls
As previously described, the Modulation wheel (and the External Control wheel) can
be used for controlling various parameters. These controls allow you to define which
parameters the wheels should modulate and to what extent.
D Below each of the knobs are the letters “W” and “X”.
These are used for selecting the source that should control the parameter, and
represent the “Modulation Wheel” and the “External Control wheel” respectively.
D By clicking on any of the letters, you decide which source should control
the parameter.
You can select either, both or none. When a letter is “lit”, the corresponding
source is set to control the parameter.
D By turning the knobs, you decide how much the modulation and/or ex-
ternal control wheel should modulate the corresponding parameter.
Note that all of the control knobs are bi-polar, which means that they can be set to
both positive and negative values. Positive values are set by turning the knobs to the
right, and negative values are thus set by turning the knobs to the left:
• Setting them to positive values means that the value of the controlled parameter
will be raised if the source wheel is pushed forward.
• Setting them to negative values means that the value will be lowered when a wheel
is pushed forward.
• Keeping the knobs in the center position means that no modulation control is ap-
plied.
There is one exception to these rules, and that is the LFO 1 Amt control, which works
in a slightly different way. See below for more information about this.
The following parameters can be modulated:
F.Freq
This sets modulation control of the Filter’s cutoff frequency (see page 179).
Mod Dec
This sets modulation control of the Decay parameter in the Modulation Envelope (see
page 180).
LFO 1 Amt
This determines how much the amount of modulation from LFO 1 is affected by the
Modulation wheel and/or the External Controller wheel. It does this by “scaling” the
amounts set with the three destination knobs in the LFO 1 section (Pitch, Filter and
Level, see page 182). We’ll explain this with an example:
To use the Modulation Wheel to increase pitch modulation (vibrato), proceed as fol-
lows:
1. Turn the Mod Wheel all the way down, so that no modulation is applied.
2. Activate the “W” button for LFO 1 Amt in the Modulation section.
3. Set the corresponding knob to “12 o’clock” (zero).
4. Set up LFO 1 so that as much vibrato is applied as you want it to be when the
Modulation wheel is turned all the way up.
5. Increase LFO 1 Amt until you hear as much vibrato as you want it to be when
the wheel is turned all the way down.
If you turn LFO 1 Amt all the way up, there will be no vibrato at all when the wheel
is all the way down.
To instead use the Modulation wheel to decrease vibrato, process as follows:
1. Turn the Mod Wheel all the way down, so that no modulation is applied.
2. Activate the “W” button for LFO 1 Amt in the Modulation section.
3. Set the corresponding knob to “12 o’clock” (zero).
4. Set up LFO 1 so that as much vibrato is applied as you want it to be when the
Modulation wheel is turned all the way down.
5. Turn the Modulation wheel all the way up.
6. Decrease LFO 1 Amt until you hear as much vibrato as you want it to be
when the wheel is turned all the way up.
If you turn LFO 1 Amt all the way down, there will be no vibrato at all when the
wheel is all the way up.
F.Res
This sets modulation control of the Resonance parameter in the Filter (see page 179).
Level
This sets the amount of amplitude envelope modulation of each zone’s level. The level
set here will be the level of the highest point of the Amp Envelope.
LFO 1 Rate
This sets modulation control of the Rate parameter in LFO 1 (see page 182).
