I have decided to put my MBFM on hold. And build a MB6582 first. This way i can see how a frontpanel design works out before i order a new design for the MBFM.
I finally got my MBFM properly running. I had some trouble with the bankstick. Which weren't detected. After some measuring i found out the input voltage was to low. So i altered the cabling on the multi voltage transformer. Now its eating 8 volts instead of 6 and its working quite well.
So after that i could upload the patches and start enjoying some sounds.
