Poly Key Timer
This processor starts a timer which begins counting down whenever a key is pressed,
and stops and outputs its value when the key is released. The value of this timer can be
used on any voices assigned to the key after the key release. The Poly Key Timer is a
special modulation source controlled by the key and not the voice.
Poly Key Timer can be used to control the volume of a Release Layer in order to reduce
its volume the longer a key is held. This control is commonly used on grand piano
presets to lower the pedal damper volume the longer the keys are held.
Channel Ramp
This processor generates a single negative going slope whenever the first key is
depressed on the MIDI channel. This preset level processor was originally designed to
simulate the percussion key click on Hammond organs, but you may find other uses.

time
The Channel Ramp instantly resets when all notes have been released and the next first
key on the MIDI channel is pressed. The value of the ramp rate sets the increment. Large
values produce fast ramps and small values produce slow ramps.
To use the Channel Ramp as a first-note decay envelope, patch the Channel Ramp out
to Amp Volume and set the Amp Envelope for a fast attack and 100% sustain and short
release.
