Percussion is a characteristic feature of tone wheel organs. It’s especially useful while soloing,

since percussion adds an extra “plink” (actually an extra tone at a dened harmonic) to the

attack. You can reach the percussion parameters by pressing the Perc1 and Perc2 soft buttons.

Parameter Range of Values

Percussion Off, On

Volume Soft, Loud

Decay Slow, Fast

Harmonic Low, High

Velocity Tracking 0 to 100%

Low Harmonic Drawbar 1 to 9

High Harmonic Drawbar 1 to 9

Steal Bar Drawbar 1 to 9

Percussion

This is where you turn the percussion eect on or o. Percussion is created by a decaying

envelope applied to one of the nine drawbars. The percussion eect 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 o by pressing Bank button 5

(labeled Percussion On/O.) Bank button 5 also sends and responds to MIDI CC 73; values

64-127 = On, values 0-63 = O.

Volume

This parameter switches between loud and soft percussion settings. The actual amplitude is set

on the PERC2 page. You can toggle between loud and soft by pressing bank Button 6 (labeled

Percussion Loud/Soft.) Bank button 6 also sends and responds to MIDI CC 71; values 64-127 =

Loud, values 0-63 = Soft.

Decay

This parameter switches between fast and slow percussion settings. The actual decay rate is set

on the PERC2 page. You can toggle between slow and fast decay by pressing Bank button 7

(labeled Percussion Decay F/S.) Bank button 7 also sends and responds to MIDI CC 70; values

64-127 = Fast, values 0-63 = Slow.
