Usage
HX3 MIDI Expander (or any other HX3 sound module) and HX3 Drawbar Controller
should be powered on the same time; switch on HX3 sound module first if HX3
Drawbar Controller is not phantom-powered. On power-up (either through MIDI
phantom supply or wall wart), HX3 Drawbar Controller will wait a few seconds until
HX3 module is ready to accept MIDI data. Wait time is indicated by a "running light"
on button LEDs. After wait time, HX3 Drawbar Controller will send all its MIDI
controller data to the host so both settings are consistent.
Connection
Connect HX3 Drawbar Controller MIDI OUT to HX3 MIDI Expander MIDI IN/OUT jack
by standard MIDI cable. Connect your master keyboard to MIDI MERGE input of HX3
Drawbar Controller. A second keyboard or a bass pedal may be connected to
secondary MIDI IN of HX3 MIDI Expander.
When using the HX3 Drawbar Controller without phantom power supply, a small wall
wart (5.5/2.1mm jack, 9V/200mA min., plus on center) is needed for power supply.
Our SNT9 is a good choice.
Controls
Buttons control the main functions of HX3 as found on Hammond (R) B3. Button
status is indicated by LED. All buttons toggle status ON/OFF whenever pressed,
except 3 buttons for vibrato knob setting (V1 to V3, only one active like radio buttons)
and ASSIGN buttons (toggle ON/OFF, only one of them active). Percussion buttons
SOFT/FAST/THIRD get dim if percussion is all OFF.
To assign the 9 drawbars to upper manual, both buttons ASSIGN LOWER and
ASSIGN PEDAL must be off. To assign drawbars to lower manual, button ASSIGN
LOWER must be ON. To assign drawbars to bass pedals, button ASSIGN PEDAL
must be ON.
If ASSIGN PEDAL is enabled, first two drawbars control 16' and 8' of bass pedal.
Third drawbar controls bass pedal sustain. Three rightmost drawbars control SWELL
TRIM CAP (general volume of organ AO28 preamp), TONE and ROTARY AMP
simulation volume.
Additional Functions
Some MIDI gear sends annoying Program Change or Continuous Controller data you
may not want on HX3. You may enable a Program Change filter and a Continuous
Controller filter to avoid HX3 misbehaviour:
Hold "ASSIGN LOWER" button a few seconds when powering up to
enable/disable the Program Change filter.
Hold "ASSIGN PEDAL" button a few seconds when powering up to
enable/disable the Continuous Controller filter.

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.

Remove four Philips screws on back and
carefully pull out chassis a few inches.
Insert two jumpers supplied with HX3
Drawbar Controller to jumper header PL10
of HX3 mk4 board or PL18 of HX3.5 board
on positions 7-8 and 9-10 as shown in
picture. Re-assemble back plate in reverse
order and you’re done.
Note for previous version boards: On HX3 mk3, only one jumper fits on rightmost
pins of white header. Second jumper must be inserted on position JP13. HX3 mk2
boards do not have a phantom power supply feature.
Connect 5-wire MIDI cable (supplied) to HX3 MIDI Expander MIDI IN/OUT and to
HX3 Drawbar Controller MIDI OUT. HX3 Drawbar Controller will now be phantom
powered by the HX3 MIDI Expander through the MIDI cable.
Attention: Always connect wall wart to HX3 MIDI Expander. Never connect the
wall wart to Drawbar Controller when phantom power is enabled. Doing so may
damage the devices.
When connecting the HX3 Drawbar Controller to other equipment, a small wall wart
(5.5/2.1mm jack, 9V/200mA min., plus on center) is needed for power supply.
