Yamaha PSR-270 - Manual (Page 115)

115
NOTE:
*1 By default (factory settings) the PSR-270 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.
The Remote Channel can be designated by using Function parameter #81.
The messages received over the set channel are handled in the same way as
key data received from the PSR-270 itself. The following messages can be
received over the designated channel set in this Function parameter; all other
messages will be ignored.
• Note ON
• Note OFF
• Control change : Bank select MSB, LSB (Main Voice Only), Modulation,
Volume, Expression, Sustain, All sound off, All note off
• Program Change (Main Voice Only)
• Pitch Bend
*2 Messages for these control change numbers cannot be transmitted from the
PSR-270 itself. However, they may be transmitted when playing the
accompaniment or using the Harmony effect.
