•Aftertouch Pressing on the keys after they’re down generates this control signal. Aftertouch is also called channel pressure, and represents an average of all keys being pressed. This affects any keys that are held down. The harder you press on the keys, the greater the degree of modulation.
•Polyphonic Pressure This is similar to aftertouch, but each key can respond to individual pressure messages. Although the QuadraSynth Plus keyboard does not generate poly pressure, the sound generators can respond to poly pressure signals entering via the MIDI In. Example: Assign poly pressure to the sound’s amplitude in a string ensemble patch. You can then increase the level of selected notes of a held chord to “pull” some notes out of the chord.
•Pitch Wheel The two wheels to the left of the keyboard are modulation sources (see below). The leftmost wheel, Pitch, always controls the oscillator pitch but can be tied to other parameters as well.
•Modulation Wheel The rightmost wheel, Modulation, is traditionally assigned to LFO amount (level) so that rotating the wheel away from you introduces vibrato. However it is also
•MIDI Volume MIDI can produce a variety of controller messages (see the MIDI supplement in the back of this manual). Of these, controller #7, which controls channel volume, is one of the most frequently used. Example: Assign the filter cutoff as the destination, and you can have the signal become less bright as it becomes lower in volume.
•Sustain Pedal The sustain switch plugged into the sustain pedal jack provides this modulation signal.
•Pedal 1 The pedal plugged into the Pedal 1 jack provides this modulation signal. Typically, this may be mapped to AENV Amp to act as a volume pedal.
•Pedal 2 The pedal plugged into the Pedal 2 jack provides this modulation signal.
•Pitch LFO This is the same modulation signal provided by the Pitch LFO. The Frequency LFO and Amplitude LFO can also be selected as modulation sources.
•Pitch Envelope This is the same modulation signal provided by the Pitch Envelope. The Frequency Envelope and Amplitude Envelope can also be selected as modulation sources.
