MODULATION WHEEL
...........................................................................................................................................................
The PMD (phase modulation), AMD (ampli-
tude modulation), and Q BIAS (resonance) LCD
[▲/▼] controls set the corresponding modulation
parameter. “0” is the preset value. “+” settings
increase the maximum modulation depth while “–”
settings decrease the maximum modulation depth
achievable with the modulation wheel. In the case of
AMD, moving the modulation wheel while a key is
already pressed will produce no effect. The effect
will be produced if the next key is pressed.

of 6 keyboard touch response speed sensitivities:
PIANO 1, STRINGS, ORGAN, PIANO 2, WOOD
WIND, or E.PIANO. The OFFSET LCD [▲/▼]
control sets the velocity offset. “0” is the preset
value.
