HX3 MIDI Expander Version 4.25
Features
• Compact organ emulator in aluminum box, 222 x 150 x 42 mm
• Authentic reproduction of generator, tapering, key contacts, percussion and
vibrato by FPGA (Field Programmable Gate Array) and physical modelling
• Tunable in range of A = 433 through 447 Hz
• Extremely low internal latency of 50 microseconds Key-to-Audio. However,
MIDI transmission delays are about 1 ms per note played.
• Natural key click by "rattling" contacts
• Accurate Rotary simulation with separate 122 amp output
• Dual MIDI IN for 2 separate keyboards or bass pedal
• LEDs show vibrato and percussion setting
• LCD display and menu system with 2x16 presets and parameter tuning
• Swell (expression) pedal and footswitch jacks
• Mini-USB for firmware updates and parameter editor
• Built-in reverb DSP with 3 levels
• Hand-crafted in Germany
Default MIDI setting is channels 1/2/3 for upper/lower/bass, MIDI CC NI B4 with
Sustain on CC #64.
DC input 9 to 12V, 500 mA min., 5.5/2.1 mm plug, plus on center.

HX3 MIDI expander is a tonewheel
organ emulation with all B3 features
in a small box. Controlled completely
via MIDI, selectable CC-sets for
various keyboards. 30 presets (to be
stored locally), unlimited polyphony,
many parameters tweakable by
simple menus - like key click
response, more or less percussion
punch etc. And, of course, it yields
the legendary unmatched HX3
sound.

Page 2: Eu Conformity Declaration
Only use appropriate power supply as advised. Input voltages exceeding 15V may damage the device. Designed for indoor use only. Do not use HX3 Drawbar Expander in moist places. Do not spill liquids or solvents into unit. No user-serviceable parts inside. Refer to qualified technician or service representative if problems occur. - Page 3 1.0 Jack Connections The HX3 expander module has two 1/4" mono audio output jacks, one DC input jack, one USB mini connector and two accessory jacks on back panel. • AUDIO1/AUDIO2: Typically rotary simulation stereo output, may be configured by menu to custom setting. Output level is approx. 300 mV at full swell.

Organ's swell pedal position is controlled by an expression pedal or MIDI CC #11 “Expression”, whichever occurs last. HX3 resembles a loudness curve similar to the swell pedal of a classic tonewheel organ, so volume will not reach zero. We recommend connecting an expression pedal Yamaha FC-7 or similar (1/4"... - Page 5 The menu system consists of about 50 entries. A "<" arrow will direct to the parameter to be changed. Vertical arrows indicate if parameter is at limits or not. 3.1 Main Display Upper/Lower • DrbUXXXXXXXXX - default main menu, shows upper drawbar settings as numbers 0 to 8 (here represented as "X").
- Page 6 3.2 Defaults Group Step downwards to reach lower manual settings; change to desired value by turning incremental encoder knob. Save changes to current preset by pressing knob for more than 2 seconds. On “live” drawbar preset 0 (DrbL) any changes are always saved temporarily and restored when returning from preset to “live”...
- Page 7 3.2.1 Split Configuration Keyboard split default is pedal mapped to lower manual on first 25 keys (console organ pedal range, two octaves). To save split mode and split point to power-on default, go to menu entry “Split Mode” and press encoder knob for 2 seconds. Default split modes may be changed by menu: Split Manual switches split mode on or off.
- Page 8 3.2.2 Output Configuration HX3 generates five output signals: rotary stereo simulation left/right, plain organ, bass pedal, and organ with rotary tube amp simulation. All output signals may be routed to any output jack. Two configurations are available, so you may set these for your own needs and toggle between them simply by "Audio Jacks"...
- Page 9 HX3 Remote application. ‘NI B4 .’ to 'Custom CC .': Sostenuto enabled CC sets are marked with a full stop (dot). Per default, HX3 recognizes MIDI CC #64 as “Sustain”. Same sets as above with dot will recognize MIDI CC #64 as “Sostenuto”...
- Page 10 3.2.4 Vibrato Group Detailed modelling of scanner vibrato yields lots of adjustable parameters. Avoid to randomly change parameters as they are intended for real organ enthusiasts – you should know what you’re doing. • Scanner Gears adjusts scanner drive gearing and therefore vibrato frequency.
- Page 11 3.2.6 Generator Group • TG Gears Tune sets organ generator tuning in range from A = 433 through 447 Hz • TG Flutter adjusts tone generator "sloppyness" (spring clutch tension, bearing precision). • TG Leakage sets tone generator leakage to o 'OFF' (never seen that) o 'New Organ' (recapped/new generator), o 'Old Organ' (higher leakage on several notes) or...

3.3 Rotary Group A few common parameters for rotary sim are available on menu. HX3 imlements a 4- beam direct/reflection model along with 512-pole FIR filter for horn simulation and a separate 2-beam direct/reflection model for rotor simulation. Most of parameters are editable through HX3 Remote application;... -
Page 13: Midi Control
As default, all HX3 controllers are OFF. Do not use any controller button or drawbar unless HX3 is ready to accept its data (drawbar preset displayed). It is a good idea to power up HX3 before your MIDI master keyboard or master controller. - Page 14 The “Brightness” knob controls AO28 “tone” parameter in HX3. There is no key click emulation in HX3 (it is just there!), so you may not adjust key click (a real Hammond does not have key click adjustment, either). The “Key Click” knob controls the bass sustain instead.
- Page 15 In case it does not, you may use a separate wall wart for the HX3 Drawbar Controller or need to open the device and set two jumpers to enable phantom supply on the HX3 MIDI Expander.
- Page 16 5. HX3 Apps HX3 Remote for Windows application is a convenient way to update or maintain your HX3 drawbar expander. It allows for firmware and sound engine updates, parameter tweaking and preset setup for experienced users. HX3 Update for Windows application is a "one click solution" to update your HX3 mk2/mk3/mk4 board or expander.
