Preset Modulation Processors

Processors
There are also two “Preset Level” modulation processors located in the
“Preset Patchcords” screen of the Edit menu. It is important to understand
that although the preset processors
originate
at the
Preset Level PatchCords
,
their output is used
in the
Layer PatchCords.

Preset Modulation
Processors start working as
soon as the preset is selected.
The Layer Modulation
Processors take effect only
when a key is pressed.
Like the Layer Lag processors
down rapid changes in the input signal. The output “lags” behind the input
at a pre-programmed rate. Unlike the layer level lag processors, the
preset lag
takes effect as soon as the preset is selected. In contrast, the layer level lag
processors begin acting only after a keyboard key has been depressed. The
Preset Lag also has a
Lag Amount
input which controls the lag time. Positive
lag amounts increase the lag time. A MIDI controller
(front panel knob)
is
commonly used to control lag amount.
The preset lag is often used to “spin-up” and “spin-down” an LFO which
controls some other effect, perhaps left/right panning, pitch, or the filter. A
MIDI footswitch could be used as the input to the lag which acts to slow
down the instantaneous change of the switch. The slowly changing output
value is then routed using a layer patchcord to crossfade between layers or
change the speed of an LFO.
Preset Ramp
This processor generates a positive or negative going slope whenever the
first
key is depressed on the MIDI channel.
