Just got my SP-16 today. I love the workflow and simplicity of it. Just about everything is right in your face to make some nice beats right on the fly. I don't think I've ever touched a sampler that sucked you right on into it. The Dave Smith filter was perfect for filtering the beats, the FX worked rather nicely too, the ADSR with the touch interface oh boy is that fun. I was smiling and loving every second of this thing but then the kicker is that this thing is a 4/4 machine. I purchased to use this for music products but with just that limitation of only 4 measures and not being able to do complex drum patterns man it's such a let down. It's like having a race car that can lap anything on the track except it can only hold 1 gallon of gas. It really kills the usefulness of the unit for people on the production side of things. It truly is a dance machine for club beats but I'm really hurting that I have to send this thing back because it's 4 measure limitation really cripples it's ability to make complete songs.
