Preset Modulation
Processors start working as soon
as the preset is selected. The
Layer Modulation Processors
take effect only when a key is
pressed.
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 Lag
Like the Layer Lag processors (described on page 109) the Preset Lag slows
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 can be 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.
