An Overview of General MIDI
General MIDI is a specification created by the MIDI Manufacturers Association which defines
specific features that a MIDI instrument must have (see the MMA website at www.midi.org for
more information.) Among other things, the GM specification sets a standard bank of program
names and numbers, as well as a standard drum mapping layout, so that sequences created on
any GM instrument will playback with the correct instrumentation on any other GM
instrument, no matter the manufacturer. GM has many uses, for example it makes it easy for
musicians who use MIDI files to share ideas and collaborate while using different sets of
equipment. Also many instrumental versions of public domain songs can be found for free on
the internet as GM compatible MIDI files. These, like all MIDI files, offer certain advantages over
audio such as small file size, the ability to edit, orchestrate, or change tempo to easily learn from
the sequences, or even convert note information to standard notation with a third party
application.
Overview of General MIDI Mode
Once enabled, Program mode will display the set of 128 standard GM program names on the
right side of the screen (see below.) Aside from the different layout and program choice, Program
mode operates normally (see below for info on the left side of the screen.) A default GM sequence will
be loaded which sets FX sends for reverb and chorus, which are part of the GM specification.
Drum programs will also be remapped to the GM drum map. The standard PC3K programs will
not be visible until GM mode is turned off.
