Percussion Velocity Track
When Velocity Track is off for a given instrument (A-F), the effective velocity is the Velocity control value, scaled on a beat-by-beat basis by the characters in the corresponding Percussion Velocity Pattern.
When Velocity Track is active for that instrument, there is an overall scaling proportional to the current Pitch Track input amplitude, relative to full scale for the current Spectrogram/Pitch Track range.
See Adjusting for optimum Velocity Track range in the Voice Velocity Track topic.
tv=n sets the Percussion Velocity Track state for instrument v (which must be A to F, case-insensitive) to the value n, which may be any unsigned integer or valid expression, including current MIDI control values, random values, current computer keyboard states or mouse position, input or buffered notes, oscillators, and User Variables. If the value is zero, Percussion Velocity Track is off; any other value sets it on.
Alternatively, you can use x instead of a value to toggle the current state. For example, tB=x toggles the Velocity Track state of Percussion Instrument B.
You can use G instead of A-F to set or toggle all Velocity Track states at once.
