Using the SH-201 together with your computer or another sound module
MIDI (Musical Instruments Digital Interface) is a standard specification that allows musical data to be
exchanged between electronic musical instruments and computers. MIDI With a MIDI cable connecting MIDI
devices that are equipped with MIDI connectors, you can play multiple instruments with a single keyboard, have
multiple MIDI instruments perform in ensemble, program the settings to change automatically to match the
performance as the song progresses, and more.
The SH-201 is equipped with the two types of MIDI
connectors, each which works differently.
MIDI IN connector
This connector receives MIDI messages that are
transmitted from external MIDI devices.
The SH-201 can receive these messages to play notes or
select patches, etc.
MIDI OUT connector
This connector transmits MIDI messages to external MIDI devices.
The SH-201’s MIDI OUT connector is used for sending the performance data of the controller section.
MIDI transmits many types of data over a single MIDI
cable. This is made possible by the concept of
MIDI
channels . MIDI channels allow messages intended for
a given instrument to be distinguished from messages
intended for another instrument. In some ways, MIDI
channels are similar to television channels. By changing
the channel on a television set, you can view the
programs that are being broadcast by different stations.
In the same way, MIDI also allows a device to select the
information intended for that device out of the variety
of information that is being transmitted to it.
MIDI uses sixteen channels; 1 through 16. Set the
receiving device so that it will receive only the channel
that it needs to receive.
Example:
Set the MIDI keyboard to send Channel 1 and Channel
2, then set sound module A to receive only Channel 1
and sound module B only Channel 2. With this setup,
you can get an ensemble performance, with, for
example, a guitar sound from sound module A and bass
from sound module B.
