Thought this might be of interest to some DIY minded folks. Looks like Leafcutter John has got in there before the official Yves Usson mod site is finished!
Wow! Yeah :))
As a side note, I am still waiting for a replacement keybed for my Minibrute bought last October.
Hope they sort this quality issue soon.
Looks easier than trying to solder to traces on the cardboard (true!) Double-sided PCB of the Roland MC-202, which was a popular target for similar mods.
