Program Change (PGM CHG)
By transmitting Program Change messages, the SPD-20 can select sounds on another MIDI device. This
parameter specifies the Program Number transmitted when Patches are switched (1–128, oFF). In the
Edit mode, each time you modify this parameter, a Program Change message will be transmitted imme-
diately from MIDI OUT, so that you can then strike the pad to check the external sound module. If you
do not wish to transmit Program Change messages, set this parameter to "oFF."
Each Pad will transmit a Program Change message on its assigned MIDI channel whenever a Patch is
selected in the Play mode. If two or more pads are assigned to the same MIDI channel and have been set
to transmit different Program Numbers, only the highest-priority pad will transmit the Program
Change (p. 67).
If while editing you attempt to make such a conflicting setting, the display will flash more rapidly to
MEMO
warn you. Also, Program Change messages for the lowest-priority pad will not be transmitted from
the conflicting pad.
When transmitting Program Numbers set with Program Change (PGM CHG) by striking the pad, set
NOTE
the Transmit Channel (TX CH) to (P 1–P16) (p. 61). However, Note Numbers from a pad set like this
are not transmitted, so you cannot use them to play an external sound module.

The following table shows how the numeric display (1–128) corresponds to the GBN
(Group/Bank/Number) Program Number scheme used in Roland devices.
GBN system
This is a way of organizing Patch memory select buttons into Groups (A/B), Banks (1–8)
and Numbers (1–8), which is used on many Roland synthesizers and sound modules.
