Percussion
Use this parameter to turn the percussion effect on or off. Percussion is created by a decaying
envelope applied to one of the nine drawbars. The percussion effect is "single-triggered,"
which means that once it's triggered, it won't trigger again until all keys (or whatever you're
using to trigger notes) go up. So if no keys are down, and you play a chord, percussion gets
applied to all notes in the chord (and in fact, to all notes that are triggered during the short
duration of the percussion envelope). Once the envelope runs its course, any notes you play
while at least one key is held down get no percussion. You can turn percussion on or off by
pressing Assignable Switch button 5 (labeled [Percussion] On/Off).
Volume
This parameter switches between loud and soft percussion settings. (Specific loud/soft
amplitudes are set with the PercLevel parameters.) You can toggle between loud and soft by
pressing Assignable Switch button 6 (labeled [Percussion] Loud/Soft).
Decay
This parameter switches between fast and slow percussion settings. (Specific fast/slow times
are set with the DecayTime parameters.) You can toggle between slow and fast decay by
pressing Assignable Switch 7 button (labeled [Percussion] Decay F/S).
Harmonic
This parameter switches between high and low harmonic percussion settings. (Specific high/
low pitches are set with the LowHarm and HighHarm parameters.) You can toggle between
low and high harmonics by pressing Assignable Switch button 8 (labeled [Percussion] Pitch
H/L).
VelTrack
This parameter specifies the degree to which key velocity controls percussion volume. A value
of zero corresponds to no velocity tracking, which is like a real tone wheel organ. Other
values add velocity tracking, so that increased velocity results in louder percussion. This
parameter typically only applies when playing a KB3 program from an external MIDI device.
LowHarm
This parameter controls which drawbar is used as the basis for the percussion when
Harmonic is set to Low. On an actual tone wheel organ, this is Drawbar 4 (2nd harmonic).
The actual pitch obtained depends on the drawbar tuning.
