Did the "bug" thing twice in my life, once FAILED: ENSONIQ VFX-SD...Bad solder killed the whole first batch ....they fixed it A YEAR OR A YEAR AND A HALF LATER..IT KILLED ENSONIQ as they recalled everything....

They had me send back the board and replaced the motherboard. Was good after that but this one killed Ensoniq...

I got an Early TASCAM DP24 ...sucker would shut off...you'd loseall your with crashes, I mean, DAAAAYYYYYYYYS of work....But they fixed it in a 6 month span and those issues are ancient history..But it was unnerving to work through fixes as a guinea pig...Not gonna ever do that again

Not sure how you beat the PA 4X
