Well, it's not a real sequencer of course...
As for me, I'd appreciate much more the ability to create bass parts by reading chords than to load\playback an audio track
Yes, I find that really cool, bass lines without the effort.
But working that into a performance is impossible, because you have to first feed the info into the machine. And then it starts. So unless you can use lots of gaps in the drums and bass, it is not practical for live use.
