Wow.. doesn't give Ensoniq (now aka EMU & Creative) a good wrap..
The closest I have had to any hardware gear dieing is an output port
going a bit dodgy on a Yamaha DX-27 (fixed with a bit of solder) and a
button dieing on an RX-5 drum machine.. Oh yeah and losing one of the
rubber bits from the hammer of a Rhodes piano
Never lost a whole machine..
