From the Android app X Drum, similar to Walk Band even for the soundfonts and samples, but this piano isn't in there and it's only here, and only one piano.
X Drum or XDrum, or whatever...
This is poorly recorded and some samples are pretty noisy btw.
X Drum belongs to Revontulet, just like Walk Band.
This is from an app, but I'm the one who screen recorded the samples with XRecorder0, a screen recording Android app on my phone that I downlaoded for screen recording, so I don't know how to license this.
