The MIDI Channel Strips
•
Click on one of the buttons for Channel 1, and move the
mouse back and forth.
The value changes according to the vertical position of the
mouse.
Technically, "Control Change" produces MIDI events. These
are processed by all MIDI tone generators, but only GM tone
generators are guaranteed to react to these MIDI events in the
way intended, if at all.
How a tone generator (not supported by the GM standard)
responds to the GM mixer will depend on the MIDI tone-
generator. Most MIDI devices, whether GM or not, use stan-
dard controller assignments, such as CC#7 for volume, etc. The
main discrepancy with most non GM devices is in program
sounds. Non GM devices will not store sounds in the same
order. For example, a non GM device may store an Organ sound
in the first program location, rather than a Piano sound, as
defined by GM.

Bank Select Messages
If your sound source "understands" bank select events, you can
choose the bank number for each of the 16 MIDI channels.
Please remember that not all synthesizers support bank select
events.
The GM/GS/XG mixer sends bank select events in the stan-
dard format. A bank is a group of up to 128 sound programs. You
can call up a specific sound program inside a bank via the
Program flip menu. For GS and XG sound modules there is an
inverted viewing method: within a sound program (reached via
a MIDI program change command) you can use the bank select
command to select among several versions of the sound program
(though not 128 versions).
