Switching Local Control On And Off - Roland HP-1 Owner's Manual

Connecting to MIDI devices

5.2 Switching Local Control on and off

When connecting a MIDI sequencer, switch off the Local Control function.
As illustrated, information describing what has been
played on the keyboard is passed to the internal sound
generator 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
severed, by setting the unit to what is known as "Local
Off."

When a Roland MT series instrument is connected, it
is not necessary to make the Local Off setting. MT
units transmit Local Off messages when their power is
switched on. If you turn on the power in the order of
the HP-1 → MT series, Local Off will be set automati-
cally.
1. Simultaneously press [Demo] and [Reverb] to
enter Function mode (both indicators flash).
2. Press the "B7" or "C8" key to set the Local function.
(See p. 17 for the exact location of these keys.)
Press the "B7" key to switch the Local function off.
Press the "C8" key (the rightmost key) to switch the
function back on again.
