Programming Basics
Modulation Processors
Diode
The diode blocks negative input values, passing only positive values.
Flip-Flop
The output of this processor alternates between a digital “1” and digital “0”
each time the input goes positive from zero or a negative value. With an
LFO input, the output will be a square wave of half the input frequency.
The value of a digital
“1” is equal to the PatchCord
amount.
Quantizer
With the input PatchCord set to 100%, the output value is limited to 16
discrete values. The value of the input PatchCord controls the number of
steps. The value of the output PatchCord controls the size of the steps.
4x Gain
This processor amplifies the modulation source by a factor of 4.

Summing Amps can be
useful in complicated patches
where you want to control a
combination of modulation
signals with a single patchcord.
The Lag processors can be used as 2 additional summing amps. Lag0sum
and Lag1sum are modulation sources which equal the sum of PatchCords
connected to the Lag in destination. The summing amp is located before
the lag processor as shown in the following illustration.
