1- I use this drum machine in the studio only, for Electro, Trance, J.M.Jarre-style (oxygène...), etc, etc.
2-The finish is incredible, but after all this is AKAI PRO! Creating a sequence is very easy if you read the manual from start to finish. The good surprise is the adjustable disco toms, awesome!
3- Analog sound ( techno, acid, trance, but not only). I use it a lot for minimal rhythms (ala J-M Jarre). The bass drum is a killer. You can "maul" the poor cat too for a dirtier sound using the appropriate feature.
Hurray for the delay on claps.
The hh is great, a lot of possibilities using accents.
I haven't used the "pattern" mode yet, for I mostly play fill-ins.
I haven't programmed the beast either. Don't forget to link the Tom Cat to a worthy reverb or another effect that will even further its capacities.
The ins/outs are comprehensive, for both audio and midi. The dynamics is as expected (no need for a compressor compared with software DMs) but that's only my own opinion.
4- Its size is adapted to environments that lack space, it's not space-consuming at all. As far as its USB connection is concerned, I haven't looked into it, I did connect it though but not testes.
I'll look further into this CAT and tell you more later...
