Gm System Level 1 - Yamaha Portatone PSR-410 Owner's Manual

*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 fingering.
*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.
00H: GM melody voice.
7FH: GM rhythm voice.
The default for channel 10 is 7FH. Other channels are 00H.
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
Fine tuning: BnH, 64H, 01H, 65H, 00H
Coarse tuning:
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.
*9. GM melody voices 0 through 127 become panel voices 1 through
128.
Rhythm voices 0, 8,16, 24, 25, 32,40, and 48 become panel
voices 1 through 8.

GM System Level 1

Default: 02H, 00H
Default: 40H, 00H
BnH, 64H, 02H, 65H, 00H
The existing MIDI protocol allows performance and other data to be transferred be-
tween 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 software 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 stand-
ard recognized by the International MIDI Association is known as "GM System Level 1."
The PSR-410 voice allocation complies with the GM System Level 1 standard.
*10. Exclusive.
<GM1 System ON> F0H, 7EH, 7FH, 09H, 01H,
All parameters except MIDI Master Tuning are reset to their
default values.
<MIDI Master Volume> F0H, 7FH, 7FH, 04H, 01H,
Allows the volume of all channels to be changed simultane-
ously (universal system exclusive).
mm is used as the MIDI Master Volume value (II is ignored).
The default value for mm is 7FH.
This message is receive-only.
<MIDI Master Tuning>
F0H, 43H, 1nH, 27H, 30H, 00H, 00H, mm, II, cc, F7H
Allows the pitch of all channels to be changed simultaneously
(panel tuning).
mmll is used as the MIDI Master Tuning value, an the actual
tuning is shown by the expression:
T=Mx200/256-100
Where T is the actual tuning value in cents. M is decimal value
represented by 1-byte using bits 0...3 of mm as the MSB and
bits 0...3 of II as the LSB.
The default values of mm and II are 07H and 0FH, respectively.
n and cc are also recognized.
This value is not reset by a GM System ON or Reset All Con-
trollers message.
This message is transmitted and received.
<Bulk Dump>
bl and bh represent the total byte count as bl+bh*128.
