Yeah mc202 is a bit like the sh101, but has some other tricks like accent i think! It does not need fx but opens a whole new beautiful world with FX, especially a bit of reverb or delay! It’s a classic synth that lots of warp artists used and i love the sound but it’s difficult to program. I still have mine but also have sh01a which is easier. I wanted to circuitbend/modify my mc202 but I haven’t used it in years (so many gear) but I certainly will because it would be superb to let it sequence by the A4 with conditional trigs! cv mods for filter trigged by A4 and audio routed to A4’s FX which is also sequencable!
I would try out the XD when it’s in the shops, then you can make a better decision!
