The PSR-550 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-550 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).
What You Can Do With MIDI
●Use the PSR-550 as a multi tone generator (playing 16 channels at one time).
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).
Receive mode for all channels set to “XG/GM.”
MIDI receive settings (page 115).
•When using a personal
computer, special software
(sequencer software) is
needed.
●Play music from another keyboard (no tone generator) using the PSR-550 XG tone
generator.
MIDI receive settings (page 115).
●Record performance data (1-16 channels) using the PSR-550 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-550 (playback).
