MIDI performance data and
commands are transferred in
the form of numeric values.
Since MIDI data that can be
transmitted or received varies
depending on the type of MIDI
device, check the "MIDI Imple-
mentation Chart" to find out
what MIDI data and commands
your devices can transmit or
receive. The P-90's MIDI Imple-
mentation Chart appears on
page 60.
When you are using the MIDI
connectors, set the [HOST
SELECT] switch to "MIDI"

HOST] connector, set the

according to the type of com-
puter you are using (page 47).
You can also obtain detailed
