on is released, it will switch off even if the note is sustained. If youÕre using a non-
keyboard MIDI controller, Key State will switch to 0 when the equivalent of a key
release is sent.
Key Number (KeyNum)
This is a unipolar control source that generates its signal value based on the MIDI
key number of each note triggered. That is, it generates a value of 0 in response to
MIDI key number 0, a value of 64 in response to MIDI key number 64, and so on.
Bipolar Key Number (BKeyNum)
This is like KeyNum, but generates a signal value of -1 in response to MIDI key
number 0, a value of 0 in response to MIDI key number 64, and a value of +1 in
response to MIDI key number 127.
Attack Velocity (AttVel)
This unipolar control source responds to Attack velocity values received at the
K2vxÕs MIDI In port. Velocity values of 0 cause it to generate a signal value of 0,
while velocity values of 127 will generate a value of +1. All other velocity values
will result in signal values proportionally scaled between 0 and +1.
Inverse Attack Velocity (InvAttVel)
This is the opposite of AttVel, generating a signal value of 0 in response to attack
velocity values of 127.
Polyphonic pressure (PPress)
This unipolar control source responds to poly pressure (aftertouch) messages re-
ceived via MIDI. It generates a signal value scaled from 0 to +1 based on the poly
pressure value range of 0Ñ127.
Bipolar polyphonic pressure (BPPress)
This is like PPress, but scales its signal value from -1 to +1.
Release Velocity (RelVel)
Also unipolar, this control source scales its signal value from 0 to +1 in response to
release velocity values from 0Ñ127.
Bipolar Attack Velocity (Bi-AVel)
This is similar to AttVel, but scales its signal values from -1 to +1.
Velocity Triggers 1 and 2 (VTRIG1, VTRIG2)
These unipolar control sources are switch controls, that is, they generate signal val-
ues of either 0 or +1. These must be programmed in order to have an effect; their
programming parameters are found on the VTRIG page in the Program Editor.
When a VTRIGÕs Sense parameter is set to normal, it switches to +1 when a note
plays at a dynamic level exceeding the dynamic level set for its Level parameter.
See ÒTHE VTRIG PAGEÓ in Chapter 6 in the Performance Guide for more informa-
tion.
