RS7000 is typical yamaha
Shite sequencing, terrible sounds, limited sampling.
A nice lappy, good controller, and audio realism bassline pro for the 303, and ableton.
Most groove boxes are just PC`s anyway, but with horrible soundsets and terrible limited sequencing interfaces
I played live for years with grooveboxes and all sorts of midi gear.
poo to it, you want instant, easy control with ulimited scope for converting your ideas into reality.
