Dan Upgraded to 4 over the holidays. The pattern player is great fun. Do I want a 909 all over every track - of course I do. I can see myself using it as an instrument - recording the performance in isolation and exporting to ableton etc.
Am sure there are better stem splitters out there, but am absolutely going to use it a ton going forward - for production and mixing on the fly. Integrates well, as you’d imagine, with the S4 I have - with controls to filter individual stems / add effects etc.
