EditProg:PERC
Tune
This parameter lets you tune each of the nine drawbars in semitone steps up or down.
SetDBR Soft Button
Press the SetDBR soft button to capture the current position of the drawbars into the "Preset" volumes on the
DRAWBR page.
EditProg:PERC
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 defined harmonic) to the attack of individual notes.
When you play more than one note simultaneously, only the first note you play will trigger the envelope of the
percussion tone, though notes played shortly afterwards will also be affected by this envelope. When you play
chords, all of the notes played simultaneously will get the percussive effect. (provided percussion hasn't
already been triggered.) You can reach the KB3 Program Editor's percussion parameters by pressing the Perc
and Perc2 soft buttons.
Percussion
This is where you 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 go up. You can also turn percussion on or off by pressing button 5 on the front
panel of a K2500 keyboard.
Volume
This parameter switches between loud and soft percussion settings. The actual amplitude is set on the PERC2
page. You can also set volume soft or loud by pressing button 6 on the front panel of a K2500 keyboard.
Decay
This parameter switches between fast and slow percussion settings. The actual decay rate is set on the PERC2
page. You can also set decay fast or slow by pressing button 7 on the front panel of a K2500 keyboard.
Harmonic
This parameter switches between high and low harmonic percussion settings. The actual pitch is controlled by
the LowHarm and HighHarm parameters. You can also toggle between high or low harmonics by pressing
button 8 on the front panel of a K2500 keyboard.
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.
