Omni On/Off
When set to Omni On, the HP-3800/2800 will produce sound regardless of the chan-
nel that performance data is received on. This is convenient for hearing the perform-
ance data on all channels at the same time.
To set the unit to Omni On, hold down the FUNCTION button and press the key at the
right end of the keyboard (the highest note). At the same time, both the transmission
and reception channels are automatically set to channel 1.

The information below will be helpful when you wish to use your piano in combination
with a sequencer*. (One cable should run between the MIDI OUT on this instrument
and the MIDI IN on the sequencer, and another should run between the sequencer's
MIDI OUT and this unit's MIDE IN.)
* A sequencer is a device which records and plays back whatever you play on your piano
(using the sound source of the piano). The MC-50 is a representative example of a Roland se-
quencer. Another product, the Roland MT-200, combines both sequencer and sound module
in one unit.
When connections are made as illustrated below, the music you play can be recorded
into a sequencer. Then, you can hear a reproduction of it when the sequencer is played
back.

if Soft Thru on the sequencer is ON at this time, the same notes will be produced twice.
As a result, the sound will seem unnatural, and the maximum number of voices that can
be produced at once may be reduced.
