MIDI Specifications
MIDI Control
Description
Some controls can be accessed remotely via an external MIDI controller such as a computer or keyboard. The
chart below shows which notes will trigger control of various HDX functions.
Setup
You will need a standard MIDI cable. Connect the MIDI OUT from your MIDI controller to the MIDI IN port of
the HDX. Set the MIDI controller to transmit MIDI commands to the HDX on MIDI channel 6.
MIDI Sync
Syncing the HDX to an External MIDI Device
You can sync your HDX to an external MIDI device such as a drum machine, sequencer, computer, or any
other device that transmits a MIDI clock signal. Connect a MIDI cable from the external device's MIDI OUT
jack to the HDX's MIDI IN jack. Then turn on INTERLOCK on the HDX by pressing the MENU button, selecting
"Playback Options", then "Interlock". Make sure you select "On" and press down on the track knob to select it.
The HDX will then sync the tempo of the music to the MIDI clock information that it receives.
Syncing an External MIDI Device to the HDX
In addition to receiving MIDI clock, the HDX will also transmit MIDI clock, with the tempo determined by the
current reading of the HDX beat counter.
This allows you to sync an external MIDI device to your HDX.
Connect a MIDI cable from the HDX's MIDI OUT jack to the external device's MIDI IN jack.
The HDX will
transmit MIDI clock to the external device, as well as MIDI start and stop commands. In this way, you can
sync a drum machine or sequencer to the HDX.
