Control Sources
Main Control Source List
4-11
101 Inverse Attack Velocity (InvAttVel)
This is the opposite of AttVel, generating a signal value of 0 in response to attack
velocity values of 127.
102 Polyphonic Pressure (PPress)
This unipolar control source responds to poly pressure (aftertouch) messages
received via MIDI. It generates a signal value scaled from 0 to +1 based on the poly
pressure value range of 0Ñ127.
103 Bipolar Polyphonic Pressure (BPPress)
This is like PPress, but scales its signal value from -1 to +1.
104 Release Velocity (RelVel)
Also unipolar, this control source scales its signal value from 0 to +1 in response to
release velocity values from 0Ñ127.
105 Bipolar Attack Velocity (Bi-AVel)
This is similar to AttVel, but scales its signal values from -1 to +1.
106, 107 Velocity Triggers 1 and 2 (VTRIG1, VTRIG2)
These unipolar control sources are switch controls, that is, they generate signal
values 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
page 6-44 of the
MusicianÕs Guide
for more information.
108, 109 Random Variants 1 and 2 (RandV1, RandV2)
These are similar to GRandV1 and GRandV2, but are local, so will affect each
control source parameter independently.
110, 111 ASR1, ASR2
These are programmable envelopes with three segments, Attack, Sustain, and
Release. Their control source signals are unipolar. See page 6-42 of the
MusicianÕs
Guide
for a thorough explanation.
112, 113 FUN1, FUN2
These generate their control source signals by combining the control signal values
of two programmable inputs, and performing a mathematical function on the
result. Their control signals can be unipolar or bipolar, depending on the control
sources assigned as their inputs. See page 6-43 of the MusicianÕs Guide. FUN2
becomes global (GFUN2) when the Globals parameter on the COMMON page in
the Program Editor is set to On.
114 LFO1
LFO1 can be unipolar or bipolar depending on the value set for the Shape
parameter on its programming page. See page 6-40 of the MusicianÕs Guide.
