HP-1 – Owner’s Manual
ENGLISH ENGLISH
ENGLISH ENGLISH ENGLISH ENGLISH
By connecting an external MIDI device and exchanging performance data, you can control the performances on one
device from the other. For instance, you can output sound from the other instrument or switch Tones on the other
instrument.
MIDI stands for Musical Instrument Digital Interface, an international standard which allows performance information
to be communicated among electronic musical instruments and computers.
The HP-1 provides MIDI connectors, which allow performance data to be exchanged with external devices. When these
connectors are used to connect the HP-1 to external devices, an even wider range of possibilities becomes available.
Connection examples
To prevent malfunction and/or damage to speakers or
other devices, always turn down the volume, and turn
off the power on all devices before making any con-
nections.
Playing the HP-1 from a MIDI sequencer/recording
an HP-1 performance on a MIDI sequencer
Switch off the Local Control function if you have con-
nected the HP-1 to a MIDI sequencer (p. 18). Also set
your MIDI sequencer to MIDI Thru mode (so that
messages received at MIDI IN will be re-transmitted
without change from MIDI OUT). For details, refer to
the owner’s manual of your MIDI sequencer.

5.1 Selecting the MIDI transmit channel
Here’s how you can set the transmit channel and make other MIDI-related settings.
1.
Simultaneously press [Demo] and [Reverb] to
enter Function mode (both indicators flash).
2.
Press the “C6”~“D#7” keys to select the MIDI
channel.
MIDI features sixteen MIDI channels, numbered
1~16. Simply connecting a cable is not enough for
communication to take place. The connected devices
must be set to use the same MIDI channels. Other-
wise, no sound will be produced, and no sounds can
be selected.
Note: The HP-1 receives on all channels 1~16.
Note: Even in Dual mode, only the channel you specify here
will be transmitted.
