4: AFTER TOUCH DEPTH
For truly "intimate" modulation control, the SY85 allows a number of modulation
effects to be controlled via keyboard aftertouch response. The parameters in this
screen set the depth of the aftertouch modulation effects.

Amod (Amplitude modulation depth)
Sets the maximum depth of amplitude modulation (tremolo effects) applied
via keyboard aftertouch.
A setting of "0" allows no amplitude modulation, while a setting of 127
results in maximum amplitude modulation depth.
When setting up the low-frequency oscillator to apply amplitude modula-
tion, this parameter must be set to a value other than "0" if amplitude modula-
tion is to be applied via keyboard after touch.
Pmod (Pitch modulation depth)
Sets the maximum depth of pitch modulation (vibrato effects) applied via
keyboard aftertouch.
A setting of "0" allows no pitch modulation, while a setting of 127 results
in maximum amplitude modulation.
When setting up the low-frequency oscillator to apply pitch modulation, this
parameter must be set to a value other than "0" if pitch modulation is to be
applied via keyboard aftertouch.
