Lovely Big Sound
I pulled this into ReaSamplOmatic5000 in Reaper, set the start pitch to -64, and played with the attack, release, and note-offs, and I really like it. So much good stuff to play with. Obviously there's no UI, at least the way I'm using it.
Completely Love This
It's got a big unique sound. There is plenty to play with in terms of mics and effects. Quite good quality, bright and clear. I have a handful of other toy pianos, none of them provide the depth of sound found here. I am thrilled.
