Roland RG-7 manual 101, Local On, Local Off

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.”

→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.
