For the price $15, it's a quite good sound. It has some character and the sound is quite homogenic over the keyboard, although some notes have more release, it's not too obvious.The sound is not over compressed compared to Ravenscroft 275 for example.
I have to do some EQ to enhance some frequencies because when playing chords it becomes a bit unclear. The keyboard response setting could be better as there is only presets.
I think the sound is better to play classical than Jazz.
I have a crash on Reaper but I'm not sure it was due to the piano since I was using also IK plugins to EQ.
