Roland HP 236 - Connecting to MIDI Devices; Setting MIDI Transmit;Receive Channels; Omni Mode Settings; Local On;Off Functionality

In order to enable communication between two devices, you
need to run a cable, such as shown below, between their
respective MIDI connectors.
Connecting a recorder or sequencer
Setting the MIDI Transmit/Receive Channels
MIDI provides for the use of 16 channels, numbered 1-16.
When the channel used by the transmitting unit matches that
of a remote receiving unit, you can play sounds contained in
the remote unit, or change the sounds it uses.
Hold down the FUNCTION button while you press the
VIBRAPHONE button to set the MIDI Transmit/Receive
Channel:
e While the VIBRAPHONE button’s indicator is dark, the
transmission and reception channels will be set to the
same channel. The Transmit channel alone can be set
while the VIBRAPHONE button’s indicator is blinking;
whereas the Receive channel alone can be set while the
VIBRAPHONE button’s indicator is lit.

Omni On/Off
When set to “Omni ON,” the HP-236 will produce sound no
matter which channel any performance data is received on.
This is convenient for hearing the performance data on all
channels at the same time.
To set the unit to Omni ON, hold down the FUNCTION but-
ton and press the key at the right end of the keyboard (the
highest key). At the same time, both the transmission and
reception channels are automatically set to channel 1.

* Thereafter, the unit will be placed back into the Omni
OFF mode when a specific setting for the Receive channel
is made.
Local On/Off
If you intend to record into a sequencer, set it so its “Soft
Thru” function is ON. At the same time, set the piano’s Local
setting to OFF:
1. Press FUNCTION (the STRINGS button indicator should
be dark). (When this indicator is dark, it means that the
unit is set to Local ON.)

2. With the FUNCTION button still pressed, press the
STRINGS button, and confirm that its indicator has lit.
(When this indicator is lit, the unit is set to Local OFF.)

* If the HP-236 is set to “Local ON” while connected to a
sequencer set with its “Soft Thru” function “ON,” the
same notes will be produced twice. This is because the
locally produced keyboard notes first sound internally,
and then are sounded a second time when the note mes-
sages (after having been sent out the HP-236’s MIDI OUT,
and been routed through the sequencer) have arrived
back again at the HP-236's MIDI IN. The result- 11
