This is what I call a "piano for everyone". Although it's not a "piano" in the sense of an 88-key hammer-action instrument (like its bigger brother SP88X), it still has that piano-y feeling. The sound, although considered outdated today (just to mention: it comes from the MicroPiano module, manufactured in 1992), is still great.
I think every pianist/keyboardist could play it, no matter the skill level. Beginners could use it to start studying piano; professionals could use it on studio, gigs and as a master controller for modules and VSTi. Versatility is the name of this board.
The sound and feel is fantastic. The semi-weighted keys give just enough bounce for piano playing, but are not too stubborn for organ riffs.
The strings are pretty sorry, but I use a different keyboard for this so who cares? If you you get one, you'll get it for the pianos. For this, it can't be beat. I've used it live and in the studio, The reviews are consistent - stunning. Also, I don't like the AC adapter.
Excellent. Metal case.
If I lost it, I'd haul right out and get another one exactly like it.
