Feedback
Use the Feedback parameter to adjust the feedback level for the selected FM Algorithm.
Each algorithm shows a line determining the feedback path, in which the output of an
Operator is used as its own modulation source, or as a modulation source for Operators in
higher rows. Feedback is useful for creating square waveforms and noise.
Feedback can be set to values from 0-7, where 0 applies no feedback, 1 applies the least
feedback, and 7 applies the most feedback.
Oscillator Key Sync
Use the Oscillator Key Sync parameter to turn oscillator key sync off or on.
When Oscillator Key Sync is set to On, the oscillator in each FM Operator resets its phase
each time a note is played.
When Oscillator Key Sync is set to Off, the oscillator in each FM Operator does not reset
its phase each time a note is played. In some programs this can be useful for adding subtle
variations to each note played.
Amp Mod Depth
Use the Amp Mod Depth parameter to adjust amplitude modulation depth of the FM
LFO for all FM Operators in the layer. When an Operator is being used as an audio source,
changes in Operator amplitude are heard as changes in volume. When an Operator is
being used as a modulation source, changes in Operator amplitude are heard as changes in
modulation depth.
Amp Mod Depth can be set to values from 0-99, where 0 applies no amplitude modulation,
1 applies the least amplitude modulation, and 99 applies the most amplitude modulation.
The Amp Mod Depth parameter works in combination with the each Operator's AM
Sensitivity parameter on the FM Operator Page. To apply amplitude modulation to an
Operator, the FM Operator's AM Sensitivity parameter must be set to a value greater than 0
on the FM Operator Page.
Pitch Mod Depth
Use the Pitch Mod Depth parameter to make fine adjustments to pitch modulation depth of
the FM LFO for all FM Operators in the layer. Pitch Mod Depth can be set to values from
0-99, where 0 applies no pitch modulation, 1 applies the least pitch modulation, and 99
applies the most pitch modulation.
The Pitch Mod Depth parameter works in combination with the Pitch Mod Sensitivity
parameter. To apply pitch modulation the Pitch Mod Sensitivity parameter and Pitch Mod
Depth parameter must both be set to a value greater than 0.
