KEYVEL (KeyVelocity) Page
actually, since a MIDI note-on with velocity zero is interpreted by some modules as a note-
off message). So to get true inverse scaling (that is, minus 100%), you must set an offset of
127 to get the full range of velocities. Setting the offset to 127 and the scale to -100% (which
is the same as the reverse linear curve):
NOTE: Offset and Scale affect only MIDI velocities; that is, these parameters don't
change Velocity Tracking in the programs themselves. Therefore, some programs (such as
organ sounds,which often have low VelTrk values) may respond only subtly to Offset and
Scale, or not at all.
VelCurve
The Velocity Curve parameter lets you taper the velocity response. The default setting is
Linear, which means that the output velocity changes directly proportionally to the played
velocity.
Expand produces a curve that is less steep than the linear curve at keystrike velocities below
64, and steeper than the linear curve at keystrike velocities above 64. In other words, when
you're playing softly, you'll notice velocity differences less than with a linear curve, while
when you're playing hard, you'll notice velocity differences more.
Compress produces a velocity curve that is the opposite of the expanded curve—that is,
you'll notice velocity differences more when you're playing softly than when you're playing
hard.
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.
LoVel, HiVel
LoVel (Low Velocity) and HiVel (High Velocity) set the minimum and maximum velocity
limits that the current zone transmits.
A keystroke in the current zone whose velocity — after it has been scaled and offset —
is below the minimum does not generate a Note On. Neither does a keystroke whose
velocity after processing is above the maximum. These parameters are useful for "velocity
switching"—having a key play different sounds depending on how hard you strike it.
