MIDI Functions
The PSR-740/640 is an electronic musical instrument which is capable of transmitting and receiving over sixteen
channels. Imagine that there are sixteen separate pipes in the connected MIDI cable. When transmitting MIDI data
from the PSR-740/640 to an external device, MIDI data is sent through the assigned pipe (or MIDI channel) and
transmitted to the external device.
For example, several tracks can be transmitted simultaneously, including the auto accompaniment data (as shown
below).
As you can see, it is essential to determine which data is to be sent over which MIDI channel when transmitting
MIDI data (page 130).
What You Can Do With MIDI
Use the PSR-740/640 as a multi tone generator (playing 16 channels at one time).
Set: Receive mode for all channels set "XG/GM."
MIDI receive settings (page 131).
Play music from another keyboard (no tone generator) using the PSR-740/640 XG
tone generator.
Set: MIDI receive settings (page 131).
Record performance data (1-16 channels) using the PSR-740/640 Auto Accompani-
ment features on a external sequencer (such as a personal computer). After record-
ing, edit the data with the sequencer, then play it again on the PSR-740/640 (play-
back).
Set: MIDI transmit settings (page 130).
