Modulation Wheel
The mod wheel controls the amount of modulation for any program that
uses it as a modulation source. This allows you to “perform” modulation in
real time by moving the wheel. This is a great way to add expressiveness
to a sound or performance by using it to control vibrato, lter effects, and
potentially a lot more.
To choose a modulation destination for the Mod wheel:
1. In the modulation section, press the source button. Use the param-
eter knob next to the display to scroll to Mod Slot 1 if it’s not already
displayed.
2. Use the parameter knob to select the source eld. Use the value knob
to scroll through the various mod sources and choose mod wheel.
3. Use the parameter knob to select the dest eld. Use the value knob
to scroll through the various mod destinations and choose a parameter
(such as cutoff).
4. Hold down a note on the keyboard (or press the hold button and play a
note on the keyboard) and turn the mod wheel.
5. Use the parameter knob to select the amount eld. Use the value
knob to set the amount to your preference. Higher amount settings add
greater modulation the further you push the mod wheel. A negative
amount setting will apply modulation in the negative direction.
Adding Aftertouch
Aftertouch is a performance feature that allows you to add modulation to
a sound by applying additional pressure to a key after the key is already
down. The greater the pressure applied, the more modulation is applied.
The Prophet Rev2 provides monophonic (or “channel”) aftertouch,
which means that applying pressure to any key within a chord will apply
modulation to all notes currently held.
The modulation section lets you choose the amount of modulation
applied using aftertouch and also which parameters are modulated (oscil-
lator frequency, lter frequency, etc.). You can set either a positive or
negative amount.
For example, if you select the lter cutoff as modulation destination
(cutoff), set a positive amount of pressure, then press the keys harder,
the lter cutoff frequency will increase, making the lter open wider and
the sound become brighter.
Conversely, if you select the lter frequency as destination, set a nega-
tive amount of pressure, then press the keys harder, the lter cutoff
frequency will be lowered, making the lter close more and the sound
become more muted.
To choose aftertouch (pressure) as a source for modulation:
1. In the modulation section, press the source button. Use the param-
eter knob next to the display to scroll to Mod Slot 1 if it’s not already
displayed.
2. Use the parameter knob to select the source eld. Use the value knob
to scroll through the various mod sources and choose pressure.
3. Use the parameter knob to select the dest eld. Use the value knob
to scroll through the various mod destinations and choose a parameter
(such as cutoff).
4. Hold down a note on the keyboard. Then, press harder.
5. Use the parameter knob to select the amount eld. Use the value
knob to set the amount to your preference. Higher amount settings
add greater modulation the harder you press a key. A negative amount
setting will apply modulation in the negative direction.
The Prophet Rev2 provides four different pressure response settings for your
convenience. The default setting provides a linear response. To choose a different
response curve, use the pressure curve parameter in the global menu.
