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.
