Hi, a few comments:
-- I have SISM and am very happy with it. Yes the mini-pots are small, but the spacing is adequate for me to use happily.
-- Levit8 has medium-sized nobs and can handle a lot of duties SISM can
-- Joranalogue Morph4 may be interesting for you, but it is more of a mashup module than offset/attenuvert
-- WORNG Vector Space does a tone of CV mashup and everything is selected by tap
