I managed to pick up a MKII UW Machinedrum recently on eBay, which I received yesterday.
Incredible sounding machine, but unfortunately it seems to have a few ghosts inside it.
It locked up after about 30 mins of testing it out, and refused to boot back into the OS again, showed some weird figures on the display upon powering on. I found a few other threads with similar issues, mentioned reseting through the safe mode. However even getting the trig keys to work in safe mode is extremely spotty, I managed to get it to recognize + reset once today, it worked for about an hour and then exhibited the same behaviour. I’m not sure if the problem is some corruption in the software, or if there’s an issue with the hardware itself.
I’m willing to give the seller the benefit of the doubt, but I’m at a loss as to what my options are other than returning it at this stage.
If anyone has any other suggestions it would be much appreciated.
