Re: [Ensoniq-VFX-SD] keyboard fix

2010-04-26 by jammie

depends on what revision board you have the later 1,s had it factory done it the same poly boards in the eps16+ asr10 and ts10
the vfx is the same engine as the eps16+ without sampler support
if yours is factory done its a set of ribbon cable hard wired in if it is
you need to check the tracks on the pcb as the boards can flex and it can raise tracks and fracture them
you need a continuity meter and need to do a point to point test of every track very time consuming
if you find a fracture hardwire between points

Subject: [Ensoniq-VFX-SD] keyboard fix

Has anybody done the now famous keyboard hard wiring fix on their own or has everyone gone to a technician? I have one of the offending VFX units that the keyboard suddenly blasts a batch of note on messages and then freezes. I don't get a calibration error but I do get the freeze up. I once had a diagram that showed what to do, and if I remember it seemed simple enough that you solder a wire from 1 to 1, 2 to 2, etc... but I am hoping to hear from someone who has done this before to see if it is as simple as that or not. I love the sounds of the thing but it isn't much good to me if it freezes up.
