I just received this email:
Dear Paul Knight,
in June 2018 we would like to introduce a new product: Our all-new HX3.5 organ module will feature all HX3 benefits including the legendary HX3 sound, but also a range of organ simulations not found before: Think of a mighty Hammond H100 with Harp Sustain and 2nd Voice tabs, a Wersi Helios or a Böhm theatre organ - even a Vox Continental or legendary Combo organs are within reach. HX3.5 supports up to 12 Drawbars per manual with three mixtures you might define by yourself. It has additional "electronic gating" besides the classic "machanical" contacts, loadable generator waveforms (up to 96 notes), percussion on every harmonic and a complete ADSR circuit on each key to resemble a genuine Wersi or Böhm sound. You will also find an additional signal prozessor capable of various reverbs along with Pianos and GM voices.
