HX3.5 Mainboard 23
Using HX3 with Voce MIDI Drawbars
Using your HX3 board with Voce MIDI Drawbars is straightforward, as the Voce module supports
only one MIDI channel (i.e. upper manual). Please note that Voce MIDI Drawbars does not send
drawbar data unless you press the “Drawbar/Save” button, so it’s LED lits up.
Using HX3 with Doepfer d3c or other NI B4 drawbar controller
The Doepfer d3c drawbar controller is a very nice and rugged piece of gear, so we recommend it
for use with our HX3 board. It supports foot controllers and foot switches. The Keyswerk/Böhm
db4 is also compatible with NI B4 CC set. Upper, lower and bass drawbars work as usual. Also the
Percussion and Vibrato buttons work as described in d3c manual.
The BRIGHTNESS knob controls AO28 “tone” parameter in HX3. The KEY CLICK knob controls
the bass sustain. Do not use the “Harmonic content” knob as it sends the “Percussion” button’s
controller number like a continuous controller. Why that? No idea. This is definitely of no use.
Preset buttons may be used, but in a restricted way. First, HX3 yields 16 presets per manual, not
127 like NI B4. When selecting “Bank 1”, all 12 available preset buttons work on upper manual.
When selecting “Bank 2”, all 12 preset buttons work on lower manual. Doepfer d3c resends the
program change message when changing the bank, which may be annoying. Choose bank 2,
lower preset first, then bank 1, upper preset. BTW: Bank buttons do not send bank select
messages, they just add an offset to the preset buttons. Blame Doepfer for that. Doepfer d3c
preset 1 is the HX3 “Live” (preset 0) position.
Using HX3 with Hammond XK/SK series
HX3 supports most of Hammond XK MIDI controller functions. For convenience, some controllers
have been relocated to other HX3 functions:
XK Overdrive knob controls HX3 Rotary Tube Amp Volume.
XK Reverb button controls HX3 lower manual Vibrato ON/OFF.
XK Tube On button controls HX3 Reverb.
Using HX3 with Nord C1 / C2 / C2D / electro 4
As of version 5.654, the HX 3 CC Set Nord C1/C2 D also supports the double drawbars of the
Nord C2D (available in the CC Set Editor as of parameter 1700 as "Indirect Drawbars"). Settings
of the non-active drawbars are stored and recalled when switching. Switching is done by CCs
(from parameter 1690), as designed by Nord.
For the Nord electro 4, a user contributed CC Set is available for download, which can be loaded
into the CC Set Editor and transferred to the HX3.
