Harmonic

This parameter switches between high and low harmonic percussion settings. The actual pitch is

controlled by the LowHarm and HighHarm parameters. You can toggle between low and high

harmonics by pressing Bank Button 8 (labeled Percussion Pitch H/L.) Bank button 8 also sends

and responds to MIDI CC 72; values 64-127 = High, values 0-63 = Low.

VelTrack

Here is where you specify 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.

LowHarm

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.

HighHarm

Controls which drawbar is used as the basis for the percussion when Harmonic is set to High. On

an actual tone wheel organ, this is Drawbar 5 (3rd harmonic). The actual pitch obtained depends

on the drawbar tuning.

StealBar

Controls which drawbar is disabled when the percussion eect is turned on. On an unmodied

tone wheel organ, the ninth drawbar is the one disabled. Any drawbar can be selected.

Parameter Group (Available for each combination of

the Volume and Decay parameters on the PERC1 page)

Range of Values

Percussion Level 0 to 24.0 dB

Decay Time 0.01 to 5.10 seconds, in 0.02-second increments

Organ Volume Level -12.0 to 12.0 dB

PercLevel, DecayTime, OrgLevel

With these parameters you can control the amplitude and decay time of the percussion eect for

all combinations of the Volume and Decay parameters (on the PERC1 page). You can also adjust

the level of the organ relative to the percussion, for accurate emulation of classic organs.
