I think I've bought a duffer.
When playing long sustained pads the sound breaks up into a crackle between both stereo channels. Shorter sounds I don't notice this so much.
I've unplugged it from everything (no audio outs, no USB just power and headphones) and the issue is still there.
Originally I thought this a problem with my Audio Interface and ADAT causing the problem but it seems not.
I have read on this forum about voltage regulators and capacitors breaking and causing this but I'm no synth repair man although I can solder, and do have a multimeter.
Anybody have experience of how to troubleshoot this ?
I'd rather not get into a debate with the vendor from ebay and the listing did state that he "would not take returns"...although I have contacted him for his stance.
Cheers.
Rob.
