Very airy. You'd think it's a wind instruments instead of a marimba. Great atmosphere, wonderful evolving sounds giving it some character. Nice GUI with plenty of options to tweak.
Beautiful, clean piano. I particularly enjoy playing in the higher registers with plenty reverb.
Simple and effective
A bit sharp in the higher frequencies, but otherwise a very clear-sounding instrument. I like the mechanical background sound, and clever how it eventually stops a while after you stop playing. Be nice to build in a stop now function. Nice to play with.
