device's programs before making modifications through midi. Not only is this
a good practice, but it will save you a lot of down time should your midi
commands be incorrect. DigiTech does not assume any responsibility for lost
presets. Please note that the Midi Device Manual is a generic term used in
this document to refer to a device specific Midi Manual. (Example: GSP7 Midi
Implementation Manual)

Midi Channel

All DigiTech devices can be configured to listen to midi on unique channels.
All devices allow a selection of midi channels 1 through 16. Some devices
allow a channel selection of OMNI (receive midi on all channels), and some
devices allow the receipt of midi data to be disabled. Some devices allow
you to select one channel for the reception of midi data, and another
channel for the transmission of midi data. Check the Midi Device Manual for
information on how to select the midi channel for your device.

Program Change

All DigiTech devices recognize a program change command. If the receive midi
channel is the same as the channel that the program change was transmitted
on, and the new program number is legal, the DigiTech device will change to
the new program number. Midi sends program changes 0 through 127. DigiTech
numbers their programs starting at 1. Thus midi program change 0 will map to
DigiTech device program 1. Some DigiTech devices allow you to remap program
changes. Remapping program changes allows the user to select any device
program based on the midi program change. The remapping of transmitted
program changes is available on devices that can generate program change
commands. Check the Midi Device Manual to determine if your device allows
the remapping of program changes.

Continuous Controllers

A continuous controller may be associated with a device parameter. This
association is done by linking the controller to the parameter. DigiTech
uses the continuous controller to represent a percentage of the parameters
maximum value. Though this is the general principle, the exact formula for
each device can be found in the Midi Device Manual.

Channel Pressure

DigiTech treats channel pressure as a special case continuous controller.
