Hey there- Yes, I've swapped the leads around and tried each of the drum outs as well as the melodic sequencers and none of them seem to be producing any voltages!
Unrelated, probably, but I've tried updating the firmware to 1.1.0.3 on OSX 10.9.5 - initially it seems like it's working but when it starts up again, although MCC says it's got the firmware I just installed, it tells me I don't have the latest and asks me to install it. I keep getting 'failed to connect' errors.
MCC detects the device but the OSX Audio Midi Setup utility doesn't.
