love the opsix sound in general but that mc707 filter is so nice. roland really made something special with those sh-101 filters

Fourth is most musical

First one sounded like a good modern VST, the second one sounded much more analog until I heard the 3rd one, which has tons of things happening in the high end the other 3 are totally lacking. The fourth one sounded like an older VST, so I nailed it listening without even using my headphones and just through HS8 monitors. :)
