Hi, I was happy to receive my saw bench synth last week but using the only MIDI controller I currently have on hand (a KMI Qunexus and midi expander) the box seems to generate a fair amount of crackling and hiss, which would make recording the synth hard. Before you ask, this is not a result of my settings but seemed to happen uniformly despite the settings.
I tested several 1/4" cables as I initially thought it was the cable, but the noise was the same with all of them.
The adapter meets your power and pin specs, but was $5 from amazon.com, so I don't know if a cheap power supply might cause this. I am using 9v but would 12v help?
Finally, I was only a few feet away from a speaker (probably not shielded) when this was happening and did not think to test if that was a factor.
Any ideas appreciated, but I'm basically asking if my unit is defective. Thanks! RT
