Mellotronists

The Roland M-VS1 is essentially the JV card in its own box.

A while back I did a comparison between #805 and the M-VS1.  Go here:

...and scroll to the bottom.

The Roland has some interesting and usable sounds, but, yep, some of 
the pitch stretching gets nasty, so you have to play within certain 
ranges.

...kl...M400 #805 - still just a sample player
