You can make detailed adjustments to MIDI
settings.
For more information about MIDI, see the
"About MIDI" section (page 44).
The [HOST SELECT] switch on the bottom surface must be
set to "MIDI" to enable the MIDI connectors. When you use the
[TO HOST] connector, set the [HOST SELECT] switch to the
appropriate position for the type of computer you are using
(pages 44–48). In this situation, all MIDI settings described
below will affect the MIDI signal in and out of the [TO HOST]
connector.

F8.1: MIDI Transmit Channel Selection
In any MIDI control setup, the MIDI channels of the
transmitting and receiving equipment must be matched
for proper data transfer.
This parameter enables you to specify the channel on
which the P-90 transmits MIDI data.
Setting range:
Normal setting: 1
In Dual mode, Voice 1 data is transmitted on its specified
channel. In Split mode, right voice data is transmitted on its
specified channel. In Dual mode, Voice 2 data is transmitted
on the next greater channel number relative to the specified
channel. In Split mode, left voice data is transmitted on the
next greater channel number relative to the specified channel.
In either mode, no data is transmitted if the transmit channel is
set to "OFF".
Demo/preset song data and recorder playback data are not
transmitted via MIDI.

F8.2: MIDI Receive Channel Selection
In any MIDI control setup, the MIDI channels of the
transmitting and receiving equipment must be matched
for proper data transfer. This parameter enables you to
specify the channel on which the P-90 receives MIDI
data.
Setting range:
Normal setting: ALL
ALL:
A "Multi-timbre" Receive mode is available. It allows simulta-
neous reception of different parts on all 16 MIDI channels,
enabling the P-90 to play multi-channel song data received
from a music computer or sequencer.
1&2:
.
A "1&2" Receive mode is available. It allows simultaneous
reception on channels 1 and 2 only, enabling the P-90 to play
1 and 2 channel song data received from a music computer or
sequencer.
Program change and other like channel messages received
will not affect the P-90's panel settings or the notes you play
on the keyboard.
No MIDI reception occurs when Demo/Preset Song mode is
engaged.
F8.3: Local Control ON/OFF
"Local Control" refers to the fact that, normally, the P-90
keyboard controls its internal tone generator, allowing
the internal voices to be played directly from the key-
board. This situation is "Local Control On," since the
internal tone generator is controlled locally by its own
keyboard.
Local control can be turned OFF, however, so that the P-
90 keyboard does not play the internal voices, but the
appropriate MIDI information is still transmitted via the
MIDI OUT connector when notes are played on the key-
board. At the same time, the internal tone generator
responds to MIDI information received via the MIDI IN
connector.
