Phew.. Finally I managed to flash the ATmega on my Hackme Rockit synth even though I liked how unexpected it operated.
It only took me like six hours time, four different programs (just to prevent me from learning a command line tool which at the end turned out not to be that difficult ) and twelve cups of coffee to get it working.
Still not tested though. If I'm lucky it should behave normal now - if not (which I really do not hope) I need to continue troubleshooting parts and soldering.
fingerscrossedAnd the moral of the story: If one tries to save time and effort it eventually doubles or even triples the amount of work/time.
