all) for the MIDI channel. When in Omni mode, POD will transmit MIDI
information on MIDI channel 1.
MIDI Messages
MIDI allows several different kinds of messages, each with a different purpose:
MIDI Program Changes - Program change messages tell a device to switch from
one sound or setup to another. With POD, program changes change from one
channel to another. So, for instance, when POD receives program change number
1, it will select Bank 1, Channel A. When it gets program change number 2, it will
select Bank 1, Channel B. And so on, as the chart in Appendix C shows.
MIDI Controllers - MIDI controller messages allow you to control a device’s
parameters in real time. So, for instance, you can use a MIDI controller to vary the
setting the of the POD Drive control, or the Reverb level. Each of POD’s
parameters are mapped to a MIDI controller, so you can take full control of your
POD. The chart in Appendix D lists each POD parameter, the controller
assigned to it, and how that controller affects POD. Note that the wah and
volume pedals of the Floor Board also transmit MIDI controller messages via MIDI
when used with your POD. To minimize “zipper” noise when controlling
parameter changes via MIDI, try making gradual, rather than sudden
changes to POD settings.
MIDI Sysex Commands - Sysex stands for “System Exclusive.” Sysex
commands are special commands that only a particular device understands – they
are ‘exclusive’ to that device – as opposed to the more generic kind of program,
controller, and other messages that almost all MIDI devices understand. POD uses
Sysex to transmit the sounds that are programmed in its memory to another
device, or to receive new sounds from another device. This exchange of data is
typically called a “dump.” The emagic SoundDiver software included on your
POD Tools CD uses Sysex commands to dump POD programs to your computer
