Depends of what you're after. Myself I like MidiSpot styles because the "live and punchy" sounding, and
they are programmed in a way that fit my style of playing as well as many are made to play well for the
Scandinawian Dancefloors.
Regarding the pricelevel, yeah, a bit expensive, but they try to make a living of styles and midi, not
by build the hardware.
Yamaha is for me too CD'is or may I say, "too well studioproduced and polished". That don't mean they
are not good, but it prevent me from buy any yama keyboard so far.
When I'm out dancing and listening to the music, I would rather have musicians that dare to play a
wrong note but still make you wanna dance, rather than a orchestra that just sit there and play perfect
as written in the paper, and sometimes make everything sounds like expression never invented.
