I bought the kit version (No M) before the module was available. I think I would rather the module, but I really enjoy this KB.
I have a Moog Little Phatty Stage II, but enjoy the patching and no memory. Both filter options is nice.
I am going down the Eurorack rabbit hole, so maybe the mini would have been a good idea in hindsight, but time will tell. The pots and jacks are velvety on the MS20 Kit. I was however shorted one patch cable.
