This is a great sampler and one of the advantages it has over some of the other is the ability to tune your samples. You can sample at 3 different bit rates, where sampling at the highest will leave you will less sample time and sampling at lowest will leave you more. The sequencer is not the best, like a lot of small samplers from this time, but i believe using quantize (which it is pretty capable of) and resampling with extra silence or space at the start of samples will allow you to get that un-quantized feel. Ive heard people say its like the mini sp1200 in sound quality, definitely not in features. But a very unique piece of production gear.
I used it on the main portion of this track, even the filtering sounds throughout. Guitar -> Johnson J-station -> ST-224 or vestax handytrax -> ST-224.
