Yamaha Portasound: The amazing evolution of the PSS series
my bestie has a PSS-680 and it's pretty fun to play with. i gave it a run with the arturia beatstep pro (sequencer tracks) and i was surprised that so many of its voices could hold up even at 140+ bpm.
but alas, the drum spec is quite primitive and probably needs a midi sequencer that can change the instrument or some additional mapping on the beatstep to activate the pads.
