I finished assembling my megadrum and it worked correctly, with Superior Drummer 2.0.
A few days later, I noticed that the up button didn't work. I replaced the push button. However, the megadrum's behaviour was unstable. Instead of the vu meter screen, it showed two lines. And if you hit a pad, the bar is shown from left to right. Something like this:
.........................
||||||||..............
I updated the firmware to the last one with the Yamaha cymbals support. It worked, but now my computer can't recognise the device. I have updated the firmware many times. The firmware is sometimes charged, but most of the time fails, and the screen shows nothing, just the back light.
I have seen in other threads to change the buffer values in Midiox up to 60000. I have done it. As well, we are supposed to turn megadrum on while holding the right button after updating new firmware. I tried, but mine does nothing.
Any solution?
