Reasons I sold mine.

[ul]
[li]Over complex sampling setup & sample saving[/li]
[li]Only 8 monophonic tracks[/li]
[li]not velocity sensitive[/li]
[li]no layering of samples or key ranges[/li]
[li]No extra outputs for mixer routing[/li]
[li]CF cards kept corrupting and losing weeks of work (maybe not its fault but still this happened twice to me.)[/li]
[li]Too much menu diving[/li]
[li]Only 4 bar sequencing per pattern[/li]
[/ul]

In the end I sold mine and went over to a second hand MPC 1000 and am far happier with how it operates. The only thing I miss is the quality of the octas reverb but its not a big issue as I have some lexicon rack gear.
