System Exclusive Data<br />

Page C contains Multi parameters<br />

and Global parameters. These<br />

parameters are sent and received<br />

only by SysEx Parameter Change.<br />

In the following, all bytes are<br />

shown in hexadecimal representation.<br />

Control Change message<br />

(only Page A)<br />

Bc Status byte,<br />

c=MIDI channel<br />

nn Parameter Number 0..127<br />

(see parameter list Page A)<br />

vv Parameter Value 0..127<br />

see parameter list Page A)<br />

The Control Change messages<br />

are defined as Performance Controller<br />

(e.g. Modulation Wheel or<br />

Hold Pedal) or Sound Parameters<br />

(e.g. Cutoff or Patch Volume). The<br />

Performance Controllers are not<br />

stored with a Single-Sound. If more<br />

than one Multi Part is set to the<br />

same MIDI channel, all Parts on this<br />

MIDI channel receive the same Performance<br />

Controllers. The Sound<br />

Parameters are stored with a Single<br />

Sound. If more than one Multi Part<br />

is set to the same MIDI channel, the<br />

Sound Parameter is receiced only by<br />

the Multi Part with the lowest part<br />

number.<br />

Example: B0,21,40 Set oscillator<br />

balance (21 hex = 33 dec) on MIDI<br />

channel 1 to the middle position<br />

(40 hex =64 dec).
