Crossfade is designed to be used in tandem with the Reverse Crossfade curve, enabling you to
perform smooth crossfades between different programs.
Bump tapers velocity response to resemble a bell curve, so that notes are loudest when your
keystrike velocity is 64. Notes get softer as the keystrike velocity approaches 0 or 127.
The next four velocity curves are Reverse Linear ( Rvrs Linear ), Reverse Expand ( Rvrs Expand ),
Reverse Compress ( Rvrs Compress ), and Reverse Crossfade ( Rvrs Crossfade ). These taper
velocity in reverse of the five curves we just covered. For example, Reverse Linear’s response is
such that striking a key harder will produce a lower volume, striking it softer will produce a
higher volume, and so on. This provides a convenient way to achieve negative scaling, by letting
you set one parameter instead of two.

as you hit the keys harder (increase the
velocity) MIDI velocity increases proportionally
MIDI velocity is greatest at
medium strike velocity
Below medium strike velocity, MIDI velocity is less
than with Linear curve; above medium strike velocity,
MIDI velocity is greater than with Linear curve
