Effect parameter change MIDI messages

Use the following MIDI channels to send messages 
to the 2488 effects (see the User’s Guide for further 
details about the types of effect available on the 
2488):

Channels 1 through 8 are used for mic effects. The 
Bank Select controller is used with channel 14 to 
choose which group of eight channels or inputs is 
affected.

Bank 0: Mixer channels 1 though 8

Bank 1: Mixer channels 9 through 16

Bank 2: Mixer channels 17 through 24

Bank 3: Inputs A through H

Channel 9 is used to control the stereo dynamics pro-
cessor effect.

Channel 10 is used to control the single effect.

Channel 11 is used to control the multi-effect.

The way in which the effects are controlled is by the 
use of NRPN (non-Registered Parameters).

Controller 98 is used for the LSB of each NRPN, and 
controller 99 for the MSB.

In effect settings where more than one effect may be 
selected, the same NRPN may produce a different 
outcome, depending on the selected effect.

NOTE

All values, etc. listed in these tables are in decimal 
notation.

Example effect parameter change

This example shows the MIDI bytes (in hexadecimal 
notation) needed to set the ratio of a compressor 
effect on mixer channel 9.

Note how Control Changes 6 and 38 (decimal) are 
used for data entry.

Control Changes 96 and 97 (decimal) are used for 
increment and decrement as well.

The ratio of the compressor on mixer channel 9 is 
now set to a value of 0.

Meaning

BD 00 01

Sends a Control Change 0 (Bank Select) 
message on channel 14 to select bank 1

B0 63 00

Sends NPRN MSB to 2nd channel in group 
(mixer channel 9) on MIDI channel 1

B0 62 01

Sends 1 as NPRN LSB to 2nd channel in 
group, which controls the ratio when 
compressor is selected as mic effect

B0 06 00

Data entry Control Change LSB on MIDI 
channel 1

B0 26 00
