If they made an 88-key version with the S61 keyboard I'd be happy. The S88 mk 2 is just a weird mushy situation, to me, and I won't buy it even though I would love to for its other great features. Such a drag.
You’re right, the S61, at least the first generation model that I have, stops pretty firmly and then you have to really press down for aftertouch, firm enough that you wouldn’t accidentally engage it. The weighting is nothing like a piano though, if that is what anyone is after. Thanks for the heads up on the new S88.
