GENERAL MIDI: Affects GS and GM MIDI Standard Files
General Midi, as a standard, stipulates that playing back a Song originating from another
sequencer must bear resemblance to the original to the nearest degree. In fact, General
Midi must ensure the following:
1. Any Program Change numbers used must call up the same type of sound on the
other unit.
2. The MIDI Note numbers assigned to the drum and percussion instruments have to
be the same and on the same channel (channel 10).
3. The polyphony of the other unit must be at least as high as the original one.
4. The other unit must respond to any MIDI Control Change that have been used, such
as MIDI Volume and Modulation.
In practice, when you load a MIDI Standard File from disk into the WX memory, or
receive data via MIDI, the above stipulations will be respected if the parameter
GENERAL MIDI is ON. Furthermore all the Program Change numbers relating to the
GS Drumkits or GM Percussion sounds received on Channel 10 will be converted and
addressed to the WX Drumkits to guarantee the correct sound on the drum track.
Conversion table for GS or GM Standard transmitted to WX on MIDI Channel 10:
Drumkits P. Change WX P. Change
Standard (GM) 0-0 (incl 1-0 … 7-0) 112-1
Room (GS) 8-0 (incl 8-0 … 15-0) 113-1
Power (GS) 16-0 (incl 17-0 … 23-0) 114-1
Electric 24-0 115-1
TR808 25-0 (incl 26-0 … 31-0) 116-1
Jazz 32-0 (incl 33-0 … 39-0) 117-1
Brush 40-1 (incl 41-0 … 47-0) 118-1
Orch 48-0 ( (incl 49 -0 … 7-0) 119-1
All Pr. Changes above 49-0 recall the Standard drumkit 112-1
In transmission, the inverse is also true for Channel 10 when General MIDI is ON. For
example, if you send the WX DKStandard drumkit on channel 10, the receiving unit
receives Program change 0.
Note: Generalmusic has adopted the system where program changes from 0 to 127 are
displayed as 1-128, therefore, the Jazz Drumkit (117-1) displays program change 118-
2.
