Chapter 7. Connecting External Devices
 
 
Disconnecting the Internal 
Sound Generator and 
Keyboard (Local Control)
 
When connecting a MIDI sequencer, set Local Control to 
“OFF.” The setting is at “Local Control ON” when the RG-7 
is powered up.
As illustrated, information describing what has been played 
on the keyboard is passed to the sound module over two 
different routes, (1) and (2). As a result, you hear overlapping 
or intermittent sounds. To prevent this from happening, 
route (1) must be disabled, by setting the unit to what is 
known as “Local Off.”
 
Local On
 
The keyboard and internal sound generator are connected.
 
Local Off
 
The keyboard and internal sound generator are separated. 
No sound will be produced by the keyboard when it is 
played.
 
 
When connecting a unit in the Roland MT series, you don’t 
need to switch off Local Control. MT units transmit Local Off 
messages when their power is switched on. If you first switch 
on the RG-7, then the MT-series device, Local Control is 
automatically switched off on the RG-7.

Sending Tone Change Messages 
(Program Change/Bank Select 
MSB/Bank Select LSB)
 
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 RG-7. 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.
