PROGRAM CHANGE
START/STOP/CONTINUE
To program the Relay to respond to Program Change messages, send it the following System Exclusive
programming command:
(
) is optional
All bytes must be in Hexadecimal format (see hexadecimal conversion table at end)
if
is omitted then relay CLOSES for all programs
and OPENS for all other program numbers.
Otherwise,
are set as follows:
= 10: relay produces OPEN pulse for all programs
= 11: relay produces CLOSED pulse for all programs
= Pulse width in 8 ms increments, or 1 s increments if preceded by 00.
= MIDI channel (see MIDI channel table at end)
= Program numbers for relay to respond to
New Program Change settings overwrite previous settings.
To program the relay to close for a duration of 4 seconds when programs 5, 7, or 12 on MIDI channel 10 are received,
send it the following System Exclusive programming command:
F0 00 00 50 26 03
F7
To program the Relay to respond to Start, Stop, and Continue messages, send it the following System Exclusive
programming command:
(
is optional)
All bytes must be in Hexadecimal format (see hexadecimal conversion table at end)
is set as follows:
if
is omitted then:
= 00: relay CLOSES for Start/Continue, OPENS for Stop
= 01: relay OPENS for Start/Continue, CLOSES for Stop
if
is included then:
= 00: relay produces CLOSED pulse for Start/Continue
= 01: relay produces CLOSED pulse for Stop
= 02: relay produces OPEN pulse for Start/Continue
= 03: relay produces OPEN pulse for Stop
= Pulse width in 8 ms increments, or 1 s increments if preceeded by 00
To program the relay to close when a MIDI Start or Continue message is received, and open when a MIDI Stop
message is received, send it the following System Exclusive programming command:
