Connecting External Devices
When you have a MIDI sequencer connected, set this parameter to
Local Off. Most conventional sequencers have the Thru function set
to On, so as seen in the figure, when information describing what
has been played on the keyboard (1) arrives at the sound generator
via two separate routes (2), notes could be sounded twice or
sometimes get cut off. To prevent this, the setting called “Local Off”
is used to disconnect the route in (1).
Local On:
The keyboard and the internal sound generator are in a linked state.
Local Off:
The keyboard and the internal sound generator are in an unlinked
state. No sound will be produced by the keyboard when it is played.
When a Roland MT series instrument is connected, it is not
necessary to make the Local Off setting. The MT transmits a
Local Off message when the power is turned on. If you turn on
the power in the order of the RM-700
→
MT series, Local Off will
be set automatically.
When Composer MIDI Out is active, you can send performance data
recorded with the RM-700 to a connected MIDI device or computer.
A Program Change is a message that means “change to the Tone of
the specified number.” The device that receives this changes to the
Tone of the corresponding number.
When you choose a Program Change message (Program Number),
the Program Number will be transmitted to the MIDI device
connected to the RM-700. The MIDI device that receives the
Program Number changes the tone to the corresponding Program
Number.
Normally, the Tone is selected from the 128 Tones available. Some
MIDI devices, however, have more than 128 Tones. With such
devices, the Tone is selected through a combination of Program
Change messages and Bank Select messages. There are two parts of
a Bank Select message: the MSB (Controller 0, with a value of 0–127)
and the LSB (Controller 32, with a value of 0–127).

Some MIDI instruments can’t handle Bank Select messages.
Others can handle Bank Selects, but do not recognize the LSB
part.
