The Envelope Control (ENVCTL) Page
Adjust
This is the familiar Coarse adjust found on many other pages. Use it here to change the rate
of one of the envelope sections without reprogramming the envelope itself. This parameter
doesn't give you realtime control over the envelope. It is, however, a good way to adjust
the natural envelopes without switching to a User envelope and trying to approximate the
Natural envelope.

Key Tracking

This uses the MIDI note number of each key as the control input for the current layer's
corresponding envelope section. When the value of this parameter is greater than 1.000x,
notes above C 4 will make the envelope section run faster, while notes below C 4 will make it
run slower. When the value of this parameter is less than 1.000x, notes above C 4 will make
the envelope section run slower, and notes below C 4 will make it run faster. This gives you
realtime envelope control right from your MIDI controller. You might use it, for example, to
cause an acoustic guitar sound to decay quicker at the high end of the keyboard (set the key
tracking to a positive value).
Velocity Tracking
Use your attack velocity as the control input for the current layer's attack section (this
parameter doesn't apply to decay or release). When the value of this parameter is greater
than 1.000x, attack velocities greater than 64 make the attack section run faster, and attack
velocities below 64 make it run slower. This gives you realtime attack control over the
envelope.
Source, Depth
These two parameters work together to let you assign a control like the Mod Wheel to affect
the current layer's amplitude envelope in realtime. The value of the Source parameter defines
which control affects the envelope section, and the value of the Depth parameter defines how
much the rate is multiplied when the control is at its maximum value, 127. No effect is had
when the control is at its minimum value, 0, and Depth values are scaled for controller values
in between.
