KEYBOARDPARTNER HX3 Drawbar Controller User Manual page 4

Status of each filter (ON/OFF) toggles each time you hold the button on power-up. If
filter is enabled, its button LED flashes 3 times on startup.
The HX3 Drawbar Controller will filter SysEx, real time data and other stuff to clean
up MIDI transmission by default. Filters do only affect MIDI data sent to MIDI
MERGE input, not directly to HX3's secondary MIDI input.
MIDI send channel for upper manual is selected in a similar way on power-up:
 Hold V1 button to set MIDI channel 1 (default)
 Hold V2 button to set MIDI channel 2
 Hold V1 plus V2 button to set MIDI channel 3
 Hold V3 button to set MIDI channel 4
 Hold V1 plus V3 button to set MIDI channel 5
 Hold V2 plus V3 button to set MIDI channel 6
 Hold V1 plus V2 plus V3 button to set MIDI channel 7
MIDI channels for lower manual and bass pedals are consecutive, i.e. upper +1 for
lower and upper +2 for pedals assignment. On power-up, V1 to V3 LEDs indicate
selected MIDI channel by flashing 3 times on startup. Factory default is channel 1, so
V1 LED will flash.
Nord C2 Mode
As a factory default, HX3 Drawbar Controller sends MIDI CCs according to Native
Instruments B4 and HX3 MIDI implementation. By switching to Nord C2 mode, MIDI
CCs sent will be altered according to Nord C2 MIDI implementation.
 Hold "REV I" button a few seconds when powering up to enable/disable the
Nord C2 mode.
 On normal power up, "REV I" LED will flash briefly to indicate Nord C2 mode.
Note: Do not use Nord C2 mode with HX3 Expander module.
Phantom Supply
To enable phantom supply via MIDI cable, insert two jumpers inside HX3 MIDI
Expander as shown (picture applies to mk4 boards only)
For use with HX3 MIDI Expander with HX3 mk4 oder HX3.5 version board, you may
utilize its "phantom" power supply feature (power over MIDI cable). If phantom supply
on the HX3 MIDI Expander is not enabled from factory, you need to open the device
and set two jumpers.
