Patches and discussion for Ensoniq VFX family

recently my sd1-32 has been giving me fits. a few weeks ago i was 
performing an op when the lcd showed the mssg:"system error 
144.....   reinitialize....  press any key to continue..." similar 
mssgs have popped up and pressing any button would set it 
straight.sure i'd lose a few seqs but no further harm.this time 
however no matter what i tried it just flashed that same mssg. i 
tried a soft reboot(u no--on & off 7x), depressing the middle keys 
firmly, and begging but nada.then one day it just decided 2 work 
again.happy days are her---oh, its doing it again!crap!! if anyone 
has run in2 this prob and/or knows how 2 correct please advise.thanks 
in advance.
