Hello,
I was given a non-functioning Bit One by a friend and had it repaired at Main Drag Music in NYC.  It took them a while (and several attempts) to figure it out but they eventually got it going and i tested it in the shop.  All of the presets were wiped and when i got it home i found someone who had posted a .wav file of the preset-restore tones.  I followed the instructions and fed the tones into the synth only to have it completely stop working!  Now i can't get any sound at all out of the synth, except that at some point the synth started "burbling" some strange noise (without me even touching it) for a couple of minutes and then stopped. I can't seem to get it to make any sound at all now.  Does anyone have any suggestions??  This synth has been a heap of trouble so far and i'd love to finally figure out how to get it going....Thanks Alot!!!
