*1. The following modes can be set individually for each channel via

the panel control:

Mode 00: Reception OFF.

Mode 01: Direct tone generator control.

Mode 02: Same as keyboard note on/off operation.

Mode 03: Same as auto-accompaniment chord fingering.

Mode 04: Same as the lowest-note (bass note) played in the

auto-accompaniment chord fingerings.

*2. Channel pressure handled as vibrato.

*3. For bank selection transmission only the MSB changes.

The LSB is fixed at 00H.

*4. Bank select reception.

The bank select MSB is used for melody voice and rhythm voice

switching.

The bank select LSB is ignored.

MSB 00H: GM melody voice.

MSB 01H: Sample voice (PSR-2700).

MSB 7FH: GM rhythm voice.

The default for all the channels excepting channel 10 is 00H. Bank

select reception with channel 10 is not possible since channel 10

is assigned to the rhythm accompaniment. However, bank select

reception with channel 10 will be possible when you do the follow-

ing operation: turning the POWER back on while holding the C1

key down.

When the bank select MSB is 01H ... 7EH, all subsequent key-ons

received will be ignored.

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.

*5. Portamento control is effective only when Reception is set in the

Multi mode.

*6. A pitch bend sensitivity message is transmitted when a panel pitch

bend range setting is made.

Pitch bend sensitivity:

BnH, 64H, 00H, 65H, 00H

*7. RPN receives the following data:

Pitch bend sensitivity:

BnH, 64H, 00H, 65H, 00H

Default: 02H, 00H

Fine tuning:

BnH, 64H, 01H, 65H, 00H

Default: 40H, 00H

Coarse tuning:

BnH, 64H, 02H, 65H, 00H

Default: 40H, 00H

Null:

BnH, 64H, 7FH, 65H, 7FH

*8. Reset all controllers.

Pitch bend, channel pressure, modulation, expression, sustain,

and sostenuto are returned to their default values.

All RPN data is set to NULL.

Portamento is reset.

GM System Level 1

The existing MIDI protocol allows performance and other data to be transferred between different instruments, even if

they are from different manufacturers. This means, for example, that sequence data that was originally created to control a

tone generator from manufacturer A can also be used to control a different tone generator from manufacturer B. Since the

voice allocation in different devices from different manufacturers is usually different, however, appropriate program change

data must be transmitted to select the right voices.

The General MIDI protocol was developed to minimize confusion and the need for re-programming when playing soft-

ware created by one MIDI device on another. This has been achieved by defining a standard voice allocation in which the

same or similar voices are accessed by the same program change numbers or MIDI channels. The current standard recog-

nized by the International MIDI Association is known as "GM System Level 1." The PSR-1700/PSR-2700 voice allocation

complies with the GM System Level 1 standard.
