PSR-280/PSR-282
NOTE:
*1 By default (factory settings) the PSR-280 ordinarily functions as a 16-channel multi-timbral tone generator, and incoming data does not
affect the panel voices or panel settings. However, the MIDI messages listed below do affect the panel voices, auto accompaniment,
and songs.
• MIDI Master Tuning
• System exclusive messages for changing the Reverb Type, Chorus Type, and DSP Type.
*2 Messages for these control change numbers cannot be transmitted from the PSR-280 itself. However, they may be transmitted when
playing the accompaniment or using the Harmony effect.
*3 Exclusive
<GM System ON> F0H, 7EH, 7FH, 09H, 01H, F7H
• This message automatically restores all default settings for the instrument, with the exception of MIDI Master Tuning.
<MIDI Master Volume> F0H, 7FH, 7FH, 04H, 01H, ll, mm, F7H
• This message allows the volume of all channels to be changed simultaneously (Universal System Exclusive).
• The values of “mm” is used for MIDI Master Tuning. (Values for “ll” are ignored.)
<MIDI Master Tuning> F0H, 43H, 1nH, 27H, 30H, 00H, 00H, mm, ll, cc, F7H
• This message simultaneously changes the tuning value of all channels.
• The values of “mm” and “ll” are used for MIDI Master Tuning.
• The default value of “mm” and “ll” are 08H and 00H, respectively. Any values can be used for “n” and “cc.”
<Bulk Dump>
• This is used for saving (recording) User data (User songs and Registration Memory).
• These messages control the clock setting for the accompaniment.
<Reverb Type> F0H, 43H, 1nH, 4CH, 02H, 01H, 00H, mmH, llH, F7H
• mm: Reverb Type MSB
• ll: Reverb Type LSB

* If the received value does not contain an effect type in the TYPE LSB, the LSB will be directed to TYPE 0.
* The numbers in parentheses in front of the Effect Type names correspond to the number indicated in the display.
* By using an external sequencer, which is capable of editing and transmitting the system exclusive messages and parameter changes,
you can select the Reverb, Chorus and DSP effect types which are not accessible from the PSR-280/PSR-282 panel itself. When one
of the effects is selected by the external sequencer, “ - ” will be shown on the display.
