Modulation Processors
Modulation processors are devices which can modify modulation sources such as LFOs
and envelope generators before they are applied to a destination. The modulation
processors allow you to create patches and do tricks which would not be possible
otherwise. The following modulation processors are currently implemented:

Steps
Summing Amp
Allows you to add several
modulation sources so the
output can be controlled
by a single Cord Amount.
Switch
Outputs a full value (100)
level whenever the input
is greater than zero.
Lag Processors
Slow down rapid changes
in the input signal. The
output "lags" behind the
input. Rate is adjustable.
Absolute Value
Inverts negative values
and leaves positive values
untouched. Outputs only
positive values.
Diode
Blocks negative values
and allows positive values
to pass untouched.
Quantizer
With the input Cord set to
100% the output is limited
to 16 discrete steps.
4x Gain
This processor multiplies
the input value by a factor
of four. Used to amplify
modulation sources.
Flip-Flop
Alternates between full
value (100) and 0 each
time the input goes
positive through zero.
