Part 8: Editing Programs
•Pitch Wheel The leftmost wheel, Pitch, usually controls the oscillator pitch but can be tied to other parameters as well.
•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 default setting assigns Pedal 1 to MIDI Controller 7 to act as a volume pedal. But it can also be assigned to any other incoming MIDI controller number (Global Edit Mode, page 12) and routed to any destination in the Mod section.
•Pedal 2 Even if you’re not using a “Pedal 2,” it is still available in the Global section as an assignable controller (Global Edit Mode, page 13). This parameter is what enables you to select that incoming MIDI controller as a source for modulation.
•Pitch LFO/Filter LFO/Amplitude LFO: You can select the LFOs as modulation sources, even if they aren't being used to affect the Sound in their usual ways. Once selected, you can route them to affect some unusual things
•Pitch Envelope/Filter Envelope/Amplitude Envelope: These can also be selected as modulation sources. Try routing them to LFO speeds or the Effect Send Level of a Sound, or whatever you can think up!
•Random This provides a different modulation value every time you hit a key. Example: With vintage analog synth patches, use pitch as the destination and apply a very slight amount of random modulation. Each note will have a slightly different pitch, which simulates the natural tuning instability of analog circuits.
•Trigrate This is a Trigger Rate Follower, which monitors how fast notes are being played on the keyboard. For example, if routed to the Effect send of a Program, you could automatically have more effect when playing slowly, and less effect when playing quickly (or vice versa).
•Controllers (A, B, C, D) Four incoming MIDI controllers can be recognized by the QS and used as modulation sources. These controllers are assigned as
•Tracking Generator This accepts the output of a signal processed by the Tracking Generator module (see page 149).
•Stepped Tracking Generator This accepts the output of a signal processed by the Tracking Generator module in stepped mode (see page 150).
