-31 scales programed in
-options of anywhere from 1 to 8 octave range on touch screen
-optional MIDI functions
-the x/y axis control is somewhat intuitive, and very responsive! Great for real time work and on-the-fly change ups.
-gate arpeggiator with a slide control for precise adjustments of range/speed
-4 banks, each with limitless layering
Now for the bad:
-limited to running short loops. Out of the box, it is set up for a simple 4 beat measure. There are ways to "trick" it to get longer loops though.
-Once you record onto a loop, it's there. Period.
-screen is very small, so it is easy to bump the wrong trigger/note. Highly recommend using a screen protector and a stylus! Neither are included
All things considered, this is a great addition for anyone interested in doing any sort of electronic music. Within a matter of minutes, it is very easy to have a great sounding sample of loops thrown together. I have not played around with the vocoder functions, so I cannot vouch for the voice effects at all. This is a great tool by itself, but if you add a KP3 (The KPQuad has gotten much worse reviews), a keyed synthesizer, or computer & the right software, then it really shines! I tethered my Kaossilator Pro through a KP3, and have used it in Reason, Acid, and Ableton. It is the perfect tool for laying down a precise beat, the trumpet actually sounds like a trumpet, and the piano is very accurate as well.
For anyone dabbling in, or making a living off of electronic music, rap, or even a lot of classical or jazz, then this may well be a perfect tool for you, if the price isn't a concern.
As compared to it's little brother, the Kaossilator, this is well worth the extra money. The smaller, "portable" one is a lot more limited, and really not very useful while on the go. Do yourself a favor, and step up to this model!
