Appendix

Effect parameter change MIDI messages

Use the following MIDI channels to send messages to the 2488MKII effects (see “Effects“ on page 39):

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 processor 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.

ªExample effect parameter change

This example shows the MIDI bytes (in hexadecimal nota- tion) 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.

MIDI message

Meaning

(hexadecimal)

 

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 Data entry Control Change MSB on MIDI channel 1

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