Patches and discussion for Ensoniq VFX family

Hi!
Or maybe a new EPROM for the KPC board in the VFX would be possible?
That would be really nice actually.

get an kpc board from an eps16+ rack this is what is used when testing the mother board to see if the keyboard is functioning properly or the the mother board is functioning properly
 
it has the scanner rom and cpu and instead of the coil boards its switches are done direct from the midi input and will except poly pressure signal from other keyboards but you wont find many with poly pressure as it is an ensoniq product and all thow you can buy replacement keybeds from fatar they only have mono pressure aftertouch

Hi!
Regarding   Rackmounting the VFX:
The Keybord electronics (the little board under the   keybed), will need to be attached all the time.
The keys hemselves cannot   be removed, without changing the capacitance on the PCB-coils.
The solution   COULD be to measure this capacitance for a key (the coil), and then replacing   the coil with
a capacitor of the same value. This should be possible   somehow.

Another (more bold) solution would be to cut up the keybord,   and mount it inside the Rack-case,
which would then need to be quite   big(!).

I would say it isn't impossible to rackmount the VFX(SD et   all), but since the keyboard is Polyphonic Aftertouch
capable, and very few   new synthesizers are that, it would be crippling the whole   machine.

Another solution would be to buffer the connection between the   keybed PCB and the little computer seated under it,
keeping the   key-computer in the rack, and making some kind of connection for the keyboard   to that rackbox.

I've been thinking of doing that, but everytime I   consider it, IF it failed and destroyed the VFX, I stay away from doing   it.
Seems I love it too much, to dvelve into 'experiments in that   direction. But it might happen someday, who knows.

Well a design like the Yamaha TX7 could be possible. The large display   can be in the sloped side. 
In fact, that makes it more like a desktop   version which is also fine for me (but heck, just the original case with   keybed removed is also fine for me as is a simple casing). Desktop version   could be mounted on a rackrail plate.

But having it work over only Midi   without a keyboard seems more difficult I think. 

Any ideas for some   kind of workaround for the keyboard?
