PSR-450 Owner’s Manual
MIDI Data Format
NOTE:
1By default (factory settings) the PSR-450 ordinarily functions as a 16-chan-
nel 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, styles, and songs.
• MIDI Master Tuning
• System exclusive messages for changing the Reverb Type, Chorus
Type, and DSP Type.

the PSR-450 itself. However, they may be transmitted when playing the
style, song or using the Harmony effect.
