Midi Basics - DigiTech SDISC SYSEX1.25 Manual

MIDI Channels
All DigiTech MIDI compatible products can be set so that they 'listen' to 1 of 16
discrete MIDI channels. The devices could also be set up to receive information on all
channels in an Omni mode or to none of the channels in a Disabled mode. Please refer
to the product's user manual for further information on each specific product.
Program Changes
When the device is set to receive one or all of the MIDI channels, it will recognize a
Program Change command. If the number is legal (e.g. within the device's range of
selectable programs) the DigiTech device will respond by changing to the new program.
MIDI sends Program Changes 0 through 127. DigiTech devices begin their program
numbering with 1, thus Program Change 0 will select program 1. DigiTech products also
allow the user to 're-map' the Program Change commands so that Program Change 0
could call program 135, if so desired. Please refer to the product's user manual for
further information.
Continuous Controllers
A MIDI Continuous Controller may be 'Linked' to nearly any available parameter in a
DigiTech S-Disc™ product. Local CC links and their ranges are treated uniquely in
each program with the assignments being saved only if they are stored as part of the
program. Some DigiTech S-Disc™ products also allow Global CC links. Please refer to
the product's user manual for further information.
Channel Pressure
DigiTech products treat Channel Pressure as just another type of Continuous Controller
which can be linked to parameters for control.
Pitch Bend
Pitch Bend information is a higher resolution controller that is not supported in
DigiTech products due to the density of the information and the resources needed to
process it properly. Many MIDI control products offer the ability to map Pitch Bend to
normal Continuous Controllers if a user wanted to control a parameter with a device
such as a Pitch Bend Wheel.
