Hello i have a Crumar bit one, i bought a mod online to replace the 2 eproms in order to have midi cc on the synth.
Well im totally a noob about electronics, but on internet was claimed to be very easy mod.
In the end i couldnt put the 2 new eproms and i cant also put back the 2 old one 
So my Crumar is off, is there maybe someone in the forum very knowledgeable from Berlin that could help? Or suggest me where to go?
HELP 
I’ve good experiences with Kai at extended Berlin, he did a nice job on my pro-one when I was living there.
Thanks a lot. Yes i found them on internet and wrote to them a couple of days ago…. But for now no answers 
Hey, I may help you. Found a picture of these two little guys on their PCB. Doesn’t look that difficult. The only thing is to find the time for that. Where are you living? I live in Brieselang but work in Adlershof. What is best for you? It’s easy to get to both places with S-Bahn or Regio
Hello Martin, thanks i write you a dm
