5. Try adjusting the Alt Input Source/Level Adjust parameter to find interesting timbres. If
the Alt Input level is too low, no modulation will be applied. If the Alt Input level is too
high, the Operator will create noisy timbres. Audio signals with complex or noisy timbres
will more easily create noisy timbres when used as a modulation source, so for these
signals the Adjust parameter may need to be turned down. Audio signals with simple
timbres may be too quiet to apply modulation, so for these signals the Adjust parameter
may need to be turned up.
6. Try using the Alt Input Source/Level Source 1 and Source 2 parameters to modulate the
Alt Input level with a physical controller or other control source. This often leads to more
interesting sounds.
Alt Input Source/Level Parameters
Src Layer
Use the Src Layer parameter to select another layer in the Program to use its audio output
signal as a modulation source for FM Operators. The current Program must have more than
one layer.
To use the selected source layer as a modulation source, select an Operator on the FM
Operator page and set the Input Source parameter to Alt.
Adjust
Use the Adjust parameter to set the output level of the selected Alt Input source layer.
Vel Track
Use the Vel Track parameter to modulate the amplitude of each note of the Alt Input source
layer based on the MIDI velocity of each note played.
Positive Vel Track values will progressively increase the amplitude for higher velocities.
For example, with a positive Vel Track value, playing a velocity of 0 causes no change in
amplitude, playing each velocity further above 0 increases the amplitude by the Vel Track
amount.
Key Track
Use the Key Track parameter to modulate the amplitude of each note of the Alt Input source
layer based on the MIDI note number of each note played.
Positive Key Track values will progressively increase amplitude for each note played above
middle C, and progressively decrease amplitude for notes played below middle C. For
example, with a positive Key Track value, playing middle C causes no change in amplitude,
playing each key further above middle C increases the amplitude by the Key Track amount,
and playing each key further below middle C decreases the amplitude by the Key Track
amount.
