Using External MIDI Devices to Play the Internal Sound

Generator

1Set the Transmit Channel for the external MIDI device to match the
Basic Channel of the SPD-20 (p. 67).
2If necessary, use PATCH/VALUE [-] or [+] to select a Patch.
3When you play the external MIDI device, the SPD-20 will sound.
When a note message is received from the external MIDI device, the Instrument selected
for the pad set to the corresponding Note Number will sound.
If a Program Change message is received on the Basic Channel (p. 67), the corresponding Patch (1–99)
will be selected. (Only in the Play mode.)
The SPD-20 will not respond to incoming Program Numbers 100–128 for patch changes.

Expanding Patches to Allow Reception of Many Note

Numbers (Patch Expand)

For each Patch of the SPD-20, 32 sounds can be selected. (If Layer is on, 16 sounds.) However, when
using the unit as a MIDI sound module to play drum parts in GM System, GS Format, and other for-
mats, this is an insufficient number of sounds. Therefore, the Patch Expand function is provided to
make more sounds available for control from an external MIDI device. When Patch Expand is turned
on, the sounds selected for Patches 96–99 will also be available, in addition to the currently selected
Patch. (This provides a total of five Patches that can be played simultaneously via MIDI.) Note Numbers
27–90 are set at the factory to each of the pads with Patch Numbers 96–99 (p. 70).
The settings for the FX/PEDAL and FX/ON OFF will apply to the settings of currently selected
Patch.

How to turn the Patch Expand function on

1In the Edit mode, press [SELECT] to select the SYSTEM parameter
group.
2Use [ ] or [ ] to select PATCH EXPAND.
3Use PATCH/VALUE [-] or [+] to turn the Patch Expand function on.
4Press [EDIT] to return to the Play mode.
When the Patch Expand function is on, an “E” will be displayed to the left of the Patch
number when you are in the Play mode.
