Ok, so I bought my Megadrum used off ebay back in February 2015.
The PCB says "Megadrum STM32 ver. 3", there is another PCB that is labeled "07301A-Y5535-17" (I'm guessing this is the positional sensing add on board?).
The main problem I've had is that my Macbook Pro is 10 years old and stuck on OS 10.6.4 and I can't find any old versions of Megadrum manager to work on it. I recently got an old Ipad, but I can't find the MDCommander app to download for it.
When I bought the Megadrum, I hadn't done all my research and had already bought 3 Roland PD-120 pads. I finally had a tech wire in some resistors to "cool" down their outputs. At some point I had read something about the positional sensing not working on these pads due to the shape of the wave? Was this ever fixed in a firmware update or do I still need to have something physically wired in to fix this issue? If so, what?
Finally, I hate the plastic case and have wanted to have it in a metal rack mountable case. 2 years ago I had asked to buy one from Dmitri, but that wasn't possible so I bought my own. I want to have someone transfer all the components into this new case, part of my frustration was that the plastic case never had any of the inputs labeled. I'm not sure if the person I bought it from built it or not.
