bundle1_kHX3 System

HX3 is a completely new approach for a tonewheel organ emulation. The sound module HX3 uses neither computers, signal processors, sample players nor analog electronics for recreating the genuine tonewheel organ sound. Instead, the original plans of a vintage Hammond B3 have been transferred to a detailed physical model. HX3 comes with a top-notch stereo rotary emulation, polyphonic pedal string bass as well as a reverb with three intensities on a compact, self-contained circuit board. Just listen to our HX3 demo sound clips!

HX3 Expander - the tonewheel organ in a small box! Controlled completely via MIDI, selectable CC-Sets für NI B4, Hammond, Hamichord and other. 30 presets (to be stored locally), many "secret" HX3 parameters tweakable by menu with incremental encoder. And, of course, the legendary HX3 sound. Also available as a kit for installation in "dead" Hammond XB-2 and as bare boards for installation in other organs/instruments by skilled technician.

HX3 Drawbar Expander with complete organ controls - two sets of drawbars plus pedal and sustain drawbars, tab buttons, 11-pin Leslie jack and four configurable audio outputs.

HX3 Drawbar-Controller for use with HX3 Expander and other organs compatible to NI B4 standard.

Complete organs based on the HX3 Sound Engine come from Uhl Instruments (middle picture, model X-3) and from MAG Custom Organs. Both are excellent instruments with competitive pricing. Also, Keyboardmanufaktur in Berlin made a special MIDI Controller for HX3 Expander.
