aMS (alternate Modulation Sources)
When the AMS abbreviation is encountered, an Alternate Modulation can
be applied to the corresponding parameter. Alternate Modulation allows for
realtime control of the effect. The following table shows the available modu-
lation sources.
aMS Description Note
Off Do not use Alternate Modulation
Pitch EG Pitch EG
Filter EG Filter EG within the same oscillator
Amp EG Amp EG within the same oscillator
LFO1 LFO1 within the same oscillator
LFO2 LFO2 within the same oscillator
Flt KTrk +/+ (Filter
Keyboard Track +/+) Filter keyboard tracking
within the same oscillator +/+ The direction of the effect will
be determined by the sign (positive or
negative) of the Ramp Low or Ramp
High setting.
+/– The direction of the effect will be
determined by the sign of the Ramp
Low setting, and by the opposite sign
of the Ramp High setting (50 for a set-
ting of +50, and +50 for a setting of
50).
0/+ Ramp Low will have no AMS ef-
fect. The sign of the Ramp High set-
ting will determine the direction of its
effect.
+/0 The sign of the Ramp Low setting
will determine the direction of its ef-
fect. Ramp High will have no AMS ef-
fect.
