Yeah, I read that on the Tubbutec website about the mod; I’ve actually got no idea which mods they are, but they do replace the original cv/gate to fix the issues with that, and apparently that indicates the Tubbutec mod will work OK.
I lack the soldering skills for a project like this, so would have to send it off to Tubbutec in Germany to do the mod as I’m not sure my local synth tech would be any cheaper.
(I’m not sure when this should move to the Roland MC-202 thread; but it was on Bad Gear.)
