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 Transpose button while you press the
Vibraphone button to set the MIDI Transmit/Reccive
Channel.
1. 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-230 will produce sound
no matter which channel any performance data is
received on. This is convenient for hearing the perfor-
mance data on all channels at the same time.
To set the unit to Omni ON, hold down the Transpose
button and press the key at the right end of the keyboard
(the highest key). At the same time, both the transmis-
sion and reception channels are automatically set to
channel 1.

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 Transpose (the Strings button indicator should
be dark). (When this indicator is dark, it means that
the unit is set to Local ON.)

* [f the HP-230 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 messages (after having been sent out
the HP-230's MIDI OUT, and been routed through
the sequencer) have arrived back again at the HP-
230's MIDI IN. The resulting sound might seem quite
unnatural.
* When the Local feature is set at "Off", the sound
source of the instrument will be disengaged from the
keyboard. As a result, only the musical information
that has traveled through the sequencer and has
arrived back again will cause the instrument to
sound.
Some sequencers, such as the MT-200, automatically
send out a "Local Off" message at power up. There
are also sequencers (such as the PR-1) which are ordi-
narily used while set to Soft Thru Off, so the instru-
ment being used can be left set at Local On.
* This piano will always be set at "Local ON" whenev-
er its power is turned on.
* Whenever there are no cables connected to this
instrument's MIDI connectors, it will always be at
"Lacal ON."
