Yamaha PSR-300m - Manual (Page 18)

MOVING UP TO MIDI
• The MIDI program change number corresponding to the number
of the selected voice is transmitted when a voice is selected.
• A MIDI START message is transmitted whenever the rhythm or
accompaniment Is started, and a MIDI STOP message is
transmitted whenever the rhythm or accompaniment is stopped.
The same applies to demo and chord memory start/stop
operations.
• Accompaniment style, demo, chord memory, and transpose data
is not transmitted.
*Refer to the Remote Control Mode “MIDI
Implementation Chart” on page 34 for more details.
The Multi Mode
The Multi mode should be used when the PSR-300M is to
be used as a tone generator, for example, receiving data from a
second MIDI device (such as a sequencer). In this mode the
PSR-300M can receive on multiple MIDI channels, each chan­
nel corresponding to a different voice. The PSR-300M panel
controls will not function when the Multi mode is selected.
Multi Mode Selection
If the Remote Control mode is currently selected, the
Multi mode can be re-selected by pressing the numeric
VOICE/STYLE [0] button while holding the CHORD
MEMORY [REC] button. “I J” will appear on the display.

Multi Mode Reception
In the Multi mode the PSR-300M functions as a multi-
timbre tone generator, allowing different voices to played
on all 16 MIDI channels (channel 16 is reserved for rhythm
only). Since the PSR-300M employs the Yamaha Dynamic
Voice Allocation system, it is not necessary to specify the
number of notes that can be played via each channel. A
maximum of 28 notes can be played simultaneously via all
channels.
• MIDI note and velocity messages received on a MIDI channel will
affect only the voice selected for that channel.
• Velocity sensitivity for each voice is set to a dynamic range of 48
dB linear.
• SUSTAIN ON/OFF messages are ignored.
• A program change number will select the voice controlled via the
channel on which it is received. The new voice number is shown
on the display for approximately 2 seconds. The program change
number is the same as the voice number (00 — 99).
• Program change messages on channel 16 are ignored.
• MIDI start, stop, and clock data will be ignored.
• Refer to the Multi Mode “MIDI Implementation Chart” on
page 35 for more details.
Multi Mode Transmission
The default transmit channel in the Multi mode is the
same as that in the Remote Control mode, and can be set
via the same procedure (see below). The transmitted data is
also the same as in the Remote Control mode, except that
no MIDI start/stop message transmission occurs.
• Keyboard note ON/OFF data is transmitted via the specified MIDI
transmit channel, but the internal tone generator does not sound
(LOCAL OFF).
• The transmitted note numbers are not affected by the instrument’s
TRANSPOSE setting.
• When a new voice is selected, the corresponding MIDI program
change message is transmitted on the specified MIDI transmit
channel. The internal voice assigned to that transmit channel will
also change accordingly. The program change number is the
same as the voice number.
• The channel-16 program change number will not be transmitted.
