MIDI Parameter Settings
If you wish to use the SPD-20 to control another MIDI sound module, or use another MIDI device to
control the SPD-20, you will need to set the MIDI parameters.
You can set MIDI parameters for each pad in a pad bank (A and B), allowing you to control external
sound modules on two channels. Additionally, MIDI parameters can be set to Patches.
For more on how to set MIDI parameters, refer to p. 66.

How the MIDI Parameters Work

Transmit Channel (TX CH)

Set this parameter to match the receive channel of the MIDI sound module you have connected. If you
want a pad to play only the SPD-20’s sounds, set this parameter to “oFF.”
Besides the Transmit Channel, settings for transmitting Program Numbers by striking the pad, and for
transmitting Start and Stop messages to external sequencers are also made in the TX CH settings.
Using the Pads to Play External Sound Modules
1–16: When playing external sound modules, Note messages are sent through the Transmit
Channels set here. If you find it unnecessary to make any special setting for this, just set it to
10 (the initial value).
If you switch Patches while setting Program Changes (PGM CHG; p. 65), the Program Number is
sent through the TX CH (1–16) set here.
When You Are Not Sending MIDI Messages
oFF: MIDI messages are not transmitted.
Using the Pads to Control External Devices
With these settings Note messages are not transmitted.
P1–P16: Set this when using the pad to switch external sound module tones. The Program Number
set to Program Change (PGM CHG; p. 65) is sent via the MIDI channel 1–16 (P1–P16) accord-
ing to the timing with which you strike the pad.
S-S: Controls external sequencers and other devices by mutual transmission of MIDI Start and
Stop messages when the Pad is struck.
C-S: Controls external sequencers and other devices by mutual transmission of MIDI Continue
and Stop messages when the pad is struck.
toP: Returns the external sequencer’s Song Position to the first measure of the song.
External sound modules cannot be played when you set oFF, P1–P16, S-S, C-S, or toP, since the Note
Numbers are not transmitted. Pads set with these parameters are dedicated pads for controlling exter-
nal sound modules or external MIDI devices.
