Preventing Doubled Notes from the Sound
Generator when a Sequencer is Connected
If you connect a MIDI sequencer to the HPi-7F, set the Local Control
setting to “Local O.”
A MIDI sequencer will typically have its “Thru” function turned on,
meaning that the notes from the keyboard will reach the sound
generating section by two routes: internally within the HPi-7F itself,
and also via the MIDI sequencer. This will cause notes to be sounded in
duplicate, or to be cut o inappropriately. To prevent this, you should
disconnect the internal route by choosing the “Local O” setting.

Changing the MIDI Transmit Channel
Here’s how to set the MIDI channel that the HPi-7F will use for
transmission.
MIDI uses sixteen “MIDI channels” (1–16). When MIDI devices are
connected, and the MIDI channels of the devices are set to match, a
device can play notes or select tones on the other device.
1. Press the [Function] button [MIDI] [O] button
[Tx Channel] (p. 24).
2. Use the cursor up/down buttons to change the setting.
MEMO
If you turn this “O,” the HPi-7F will not transmit MIDI data.
The HPi-7F can receive all channels 1–16.
Transmitting Recorded Performance Data to
a MIDI Device
If the “Composer MIDI Out” setting is “On,” the recorded performance
data can be transmitted to a MIDI device or computer that’s connected
to the HPi-7F.
1. Press the [Function] button [MIDI] [O] button
[Composer MIDI Out] (p. 24).
2. Use the cursor up/down buttons to turn the setting on/o.
