I have just realised what was causing my SYSSTEM 32 error on my VFX. When I load a sound which contains the ‘8 Voice Chorus’ is brings up the error. I confirmed this by loading a working sound and manually changing the effect to the 8 voice chorus and it crashed.
I was thinking it could be the ‘Ensoniq ESP signal processor chip, 5510000102’ .
Those error messages don’t reveal too much info, without being hooked up to Ensoniq’s diagnostics computer. But it sounds like you’re on the right track. I’m presuming you’ve tried reinitializing - but if you haven’t, definitely do that next.
If it still crashes, you might try removing and then re-seating the ESP chip. If you still get the error after that, make friends with someone who owns a VFX, VFX-sd, SD-1, EPS-16 Plus, or SQ-1, and see if they’ll let you pop the ESP chip out of theirs and into yours - that way you can verify (or not) that it is the actual chip causing the error.
So I got hold of some 2.3 firmware ic’s (I was on 2.1). When I first turned on the synth it would load the faulty fx’s fine. I thought great! But after a few minutes it then fails to load the fx again. That would suggest to me that it is at least initially loading the algo’s correctly.
The Sq1 went for £114 so that wasn’t a viable option.
