Menu: Program/Synth/Osc/Select
Parameter: Trigger on key up
Value Range: On, Off
Usually, you want sounds to play when you press a key. But there are
some cases–such as a harpsichord’s release sound–where you want the
sound to play when you raise your fingers off the keys. Enable Trigger
On Key Up in such cases.
Menu: Program/Synth/Osc/Select
Parameter: FM source
Value Range: None, Osc 1, Osc 2, Filter
You can have the filter or an oscillator’s waveform modulate the
frequency of the current oscillator. The result is a more complex
waveform with richer harmonics.
Menu: Program/Synth/Osc/Select
Parameter: FM Amount
Value Range: 0 – 100%
Blend in any amount of the FM source. Higher percentages blend in
more of the FM source and create richer harmonics. Smaller
percentages blend in less of the FM source and leave a more pure tone
from your oscillator.
About Key Up Envelope Triggering:
You’ll probably want to set the envelope
trigger mode (see page 226 for more) to
“key up” so that the volume envelope does
not jump to the Release state and quickly
mute your sound when you release a key.
Alternatively, you could leave the trigger
mode to “normal” but increase the release
time so that this oscillator has a chance to
play before being muted.
