SPD-20: Patch Expand
Each patch will allow you to play 32 sounds at once, 16 if layering is used. To
access more sounds thru MIDI, the SPD-20 has a feature called Patch Expand.
When set to ON, patches 96-99, plus the currently selected patch can be played
simultaneously thru MIDI. To turn Patch Expand on, use the following procedure:
1) Press EDIT.
2) Press SELECT to select the "SYSTEM" parameter group.
3) Use the up / down arrows to select "PATCH EXPAND."
4) Press the PATCH/VALUE buttons to turn the "PATCH EXPAND" function "ON."
5) Press EDIT to return to play mode.
Note: When the Patch Expand function is on, an "E" will displayed to the left
of the Patch number when in the Play mode. Also, note numbers 35-81 are
compatible with the GM percussion map, note numbers 27-87 are compatible with
the GS Standard Set.
