What You Can Do With Midi - Yamaha PortaTone PSR-540 Owner's Manual

MIDI Functions
The PSR-540 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-540 to an external device, MIDI data is sent through the assigned pipe (or MIDI channel) and trans-
mitted 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 114).

What You Can Do With MIDI

Use the PSR-540 as a multi tone generator (playing 16 channels at one time).
Receive mode for all channels set to "XG/GM."
MIDI receive settings (page 115).
Play music from another keyboard (no tone generator) using the PSR-540 XG tone
generator.
MIDI receive settings (page 115).
Record performance data (1-16 channels) using the PSR-540 Auto Accompaniment
on a external sequencer (such as a personal computer). After recording, edit the data
with the sequencer, then play it again on the PSR-540 (playback).
