Yeah I had an S950 b4 too and sold that so what i am doing though is making loops and sampling live drums into it and then using the samples in my computer sequences, i got some old dats and stuff from live studio drummers I just dumped to my adat from protool.....also my vinyl hits, loops and chopped stuff goes into there for some good ol 12 bit processing, what I wanted to know though was on my sp12 sometimes sounds like the hi hat would sometimes double or get cut off when I would sequence sometime...I wanted to know does this happen on the 1200...I have all of the software just about known to man when I had to sell off all of my studio equipment now I have found a way to take both my hardware and software and maximize my setup...
