I just acquired one of these a few days ago. I'm pretty excited about it. I could care less about the delay section, but I think the sampler is pretty wonderful. You can only sample about one second of sound, but of course in the context of music one second could be quite a lot of time, especially for percussive sounds, and then you can always ad a bit of reverb afterwards to stretch it out. Anyway, the thing that really interests me about this is that it has CV and Gate inputs and that is the way the sample is controlled. It's the only sampler I know of that takes a digital sample and then allows you to control it with a voltage signal. This means that you can control it with your analog synthesizer or sequencer. It really opens up a whole world of possibilities if you have an analog synthesizer with an audio input; suddenly you're able to mix whatever (organic or otherwise) sampled sound you like with your voltage controlled oscillators before it hits the filter, envelope, etc. If you just wanted more oscillators you could sample your oscillator and feed it right back into your synthesizer, though with all the other interesting possibilities this seems pretty dull.
Update 8/10/12: Portamento from an analog synthesizer also effects the sample. I guess I should have expected that, but it was a nice little surprise.
