Modulation
Processors
Modulation processors are devices which can modify modulation sources
such as LFOs and envelope generators before they are applied to a desti-
nation. Modulation processors let you create patches and do tricks which
would not be possible otherwise. These modulation processors are indepen-
dently programmable on each of the four layers.
Switch
Outputs a digital "1" when the input is greater than "0".
Summing Amp
Lets you add several modulation signals together before applying them to a
destination. This processor can save PatchCords when routing the output
to multiple destinations.
Lag Processors
Slows down rapid changes in the input signal. The output "lags" behind the
input at a pre-programmed rate. There are two lag processors, Lag 0 and Lag
1. Lag 1 has a longer lag time than Lag 0.
Absolute Value
This function inverts negative input values and outputs only positive
values. This device is also called a full wave rectifier.
