*1 PSR-620 ordinarily functions as 16 MIDI channel multi-timbral tone
generator controlled by MIDI reception data. Panel voices and the
other panel settings are not affected by the MIDI message, except-
ing the followings:
MIDI Master Tuning
System Exclusive Message for controlling Reverb, Chorus and
Dsp
The Remote Channel can be designated by the panel settings. The
designated channel on the PSR-620 can be controlled by an exter-
nal device and receive all the data excepting the following control
change data:
Data entry, MSB, LSB
Portamento control
Data increment
Data decrement
NRPN LSB, MSB
RPN LSB, MSB
*2 Bank Select MSB
The bank select MSB is used for melody voice and rhythm voice
switching.
MSB 00H: Melody voice.
MSB 7FH: Rhythm voice.
Transmission: Transmitted when changing the voice, style and
song.
Reception: All channels except10 channel receive this message.
( 10 channel is fixed at rhythm voice.). But when 10 channel is set
for the remote channel or receives XG System On message, 10
channel receives this message and the rhythm voice can change
to the melody voice.
Bank Select LSB
This message is used to correspond to the panel voice numbers
higher than 128.
Bank Select LSB=00H: program change numbers 0~127 corre-
spond to the panel voice numbers 1~128.
Bank Select LSB=01H: program change numbers 0~12 corre-
spond to the panel voice numbers 129~141.
Transmission: Transmitted when changing the voice, style and
song.
Reception: This message can be received only at the channel
designated as the remote channel or the panel voice.
No voice change will occur when only a bank select is received.
When a program change is received the latest bank select value is
used.
*3 These Control Change messages are not transmitted by the PSR-
620 panel operation, but may be transmitted by the accompani-
ment style playing.
*4 NRPN transmission/reception
