I was thinking of building my own HX3 Organ (I currently use an XK3 system as the HX3 controller) using the Fatar keyboards. I know that the touch sensitivity is selectable overall but is it possible to have only one keyboard as the touch-sensitive one? This I can do with my XK3 and use this facility to play Pianos/Rhodes type instruments on the lower keyboard only.

If this is not currently possible might it be easily added?

What touch velocity do you mean? Since the standard 61 TP/8O does not offer aftertouch, I assume you mean early contact (for organ) as opposed to late contact, which enables MIDI velocity.

With the HX3 board and FatarScan you do not need different settings for the keybeds. HX3 uses early contact for the organ sound by default and at the same time late contact to compute velocity for MIDI OUT.

Thanks Christian,

Yes, it is the early/late contact settings I was wondering about. I didn't realise that it was late contact on midi out so indeed this solves the issue. Is this information in the manual? It would be useful info for everyone, I think.

The information is in the manual.
It´s more than one year ago that some users had problems with their keys and early / late contact,
so it´s now possible to set it as wanted. Default parameter is early

One final question before I go the Fatar keyboards route — I found the Hammond-Suzuki XK3 keyboards matrix diagram (the lower keyboard is the same). Is it possible this could attach to the Fatar scan board? The first connector is 16-pin but the second connector is 20-pin presumably because of the preset keys. Possible or should I give up the idea?

Download the matrix of Fatar from Fatar direct or via DOEPFER .
Then You have to compare the FATAR schematic with the Hammond Suzuki matrix.

I think they won´t be equal .
On a FATAR keyboard You have two connectors 16 pol , on for lower part of keys the othe
for the upper part.
You can compare this too with the scanFatar2 board schematics

A normal Fatar 5 octave keyboard has no negative preset keys.
If You buy a 6 octave FATAR key this also will not run because at this keys
You have other micromatch connectors with different pins.
For connecting to HX 3 equipment You always have to use 5 octave keyboard because the matrix
begins at lowest Key.

In a 6 octave keyboard the matrix begins at the LOWEST PRESET KEY - that´s th reason
Of course You can use a 6 octave FATAR key , BUT YOU HAVE TO INSTALL 5 octave RUBBER CONTACT BOARDS
instead those for 6 octave.
