Realtime Modulation Functions
You can use various MIDI messages (such as note number, velocity, aftertouch, or
pitch-bend, etc.) to control parameters in the Q20, such as delay time, room size,
etc. This is accomplished by way of the Q20Õs MIDI Modulation Matrix.
Modulation parameters are stored in the Program, and therefore can be setup
differently for each of the Programs in memory.
Use the [MODULATION] button to program which MIDI messages control which
parameters in each Program, and by how much. This is done by following three
steps:
➀ Select a Modulator (or modulation patch), of which there are 8 per Program;
➁ Choose the Target; i.e. what is to be modulated;
➂ Choose the Source; i.e. what is doing the modulating; and,
➃ Set the Amplitude, or amount, of modulation.
Keep in mind that a target may be modulated by more than one source. Likewise, a
single source can modulate as many as 8 different targets. It is this kind of
flexibility that matrix modulation affords.
Modulation sources must be received on the same MIDI channel the Q20 is set to in
order for the Modulators to function properly.
Selecting the Modulator
Once you press the [MODULATION] button, you can turn the [VALUE/ENTER] knob
to select one of the eight Modulators. Think of each Modulator as a modulation
patch which routes a Source to a Target using a particular amplitude.
➀ Press [MODULATION].
The [MODULATION] buttonÕs LED will light, and the display will read:
MOD 1 TO:DLY 1-TAP 1 DELAY TIME
The cursor appears beneath the Modulator number. This is Modulation Page 1,
which allows you to choose a Target (see below).
➁ Turn the [VALUE/ENTER] knob to select a Modulator (1Ð8).
At any time you can move between the 8 Modulators by first moving the cursor back
to the far left of the display (using the [< PAGE >] buttons), and then turning the
[VALUE/ENTER] knob to select a different Modulator.
