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.
MIDI message
(hexadecimal)
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 Data entry Control Change MSB on MIDI
channel 1
