E-200/E-100

MIDI is short for “Musical Instrument Digital Interface”. The word refers to many things, the most obvious
being a connector type that is used by musical instruments and other devices to exchange messages
relating to the act of making music.
Each time you play on the E-200/E-100’s keyboard or start the Arranger (or Song), your instrument
transmits MIDI data to its MIDI OUT. If you connect the MIDI OUT socket to the MIDI IN socket of another
instrument, that instrument may play the same notes as one of the E-200/E-100’s parts, select sounds,
etc.
MIDI is a universal standard, which means that musical data can be sent to and received by instruments
of different types and manufacturers. Furthermore, MIDI allows you to connect your E-200/E-100 to a
computer or hardware sequencer.
Connect your E-200/E-100 as shown to the right.
Channels
MIDI can simultaneously transmit and receive messages on 16
channels, so that up to 16 instruments can be controlled. Nowa-
days, most instruments –like your E-200/E-100– are multitim-
bral, which means that they can play several musical parts with
different sounds.
Note: All E-200/E-100 parts are set to receive MIDI messages. If
they do not seem to respond to the messages you send from the
external controller, you should check whether the external control-
ler’s MIDI OUT is connected to the MIDI INput of your E-200/E-100.
The E-200/E-100’s transmit and receive channels of all parts
have been set in keeping with a tacit Roland standard and are
therefore shared by all recent EM, E, G, and RA series instru-
ments. You cannot change them. They also correspond to the
track assignments of the 16-track Recorder:
MIDI Function parameters
See “Editing parameters (general procedure)” (p. 37) for how to
select and set these Function parameters (they belong to the
“MIDI” family).
Note: With the exception of “Local”, all MIDI parameter settings
are saved as soon as you leave the Function mode.
■
Local
(On/Off, Default setting: On) The Local parameter allows you to
establish or remove the connection between the E-200/E-100’s
keyboard/Recorder and the internal tone generator.
When set to “ON” (default), playing on the E-200/E-100’s key-
board or playing back a Recorder song will cause the corre-
sponding notes to sound. If you select “OFF”, the corresponding
MIDI messages are no longer sent to the internal tone genera-
tor – but they are still transmitted to the MIDI OUT port and
hence to external MIDI instruments.
Note: The setting of this parameter is not memorized when you
switch the E-200/E-100 off.
■
MIDI TxRx° (MIDI transmission and reception)
This parameter allows you to specify which E-200/E-100 parts
should transmit and receive MIDI messages:
■
Sync Rx° (MIDI synchronization)
Use this parameter to specify how the E-200/E-100 should be
synchronized (as slave) to an external MIDI sequencer, com-
puter, drum machine, etc.
“Synchronization” is a learned term for the fact that one device
(or function) is set to start and stop at the same time as
another device (or function), and to run at the same tempo
(BPM).
