Right you are, ta!

Just to add to the pool... I'm pretty sure firmware got corrupted because I played with the pedal jumper and prolly forgot to turn off power first. The LCD flashed ever ½ sec at boot with no welcome screen.

Dmitri,
I tried multiple times with MIDI-Ox, and suddenly once it worked correctly!! I think the key was that I wasn't powering up holding the left button maybe? It was still going to the bootloader screen though.

I had to try several times as well. I think restarting MIDI-Ox did the trick. Some options may call for a restart to be effectuated.

Sorry but I didn't quite understand your message. Did you loose your firmware? Can you describe in details how it happened?

I lost my firmware a couple of days ago and reloaded it throu MIDI-Ox. It took a couple of goes before it would transfer. All is fine now, I'm just sharing an experience similar to ruiner46 for others to know.

I can't descibe precisly what caused it since I did quite a few things trying to solve my dead jack problem

But fiddling with a hot hi-hat jumper, may have caused a short.

I decided to change the instructions on programming Atmega fuses to enable 'brown-out' detection. Although I myself haven't experienced any flash memory losses, evidently some have. In rare circumstances power dips could cause MegaDrum firmware erasure but I still don't understand why the boutloader could have been lost since the bootloader section is write protected. Anyway, if you programmed Atmega yourself, I recommend you to change the fuses to the values shown in http://www.megadrum.info/content/programming-mcus
