Last night I got a broken E-mu Drumulator for free from Craigslist. I can turn it on and everything appears to be functional except that it doesn't output sounds (through either the Mix output or individual outputs). However, the metronome sound comes out of the ind. out for it, but not through the mix out.
Jacks look good and I don't notice any immediate issue when I open it up, but I don't know where to look from here. I appreciate any advice you can give.
