I have it loaded in a track, I was just playing with it and if I minimize the settings stay but if I close it they are gone. It's a vst2. It has a save button at the top of the plugin window but I can't tell that it does anything. Has a preset box too but it doesn't do anything that I can tell.
I tried the Dead duck E, it has a lot of nice features but doesn't sound as good to me, it doesn't have that bell sound. It is a nice piano though.
