This is what the developer said:
I got inspired and wrote my first Android music app. The app is a USB MIDI Grand Piano App and 100% free (no ads, no fee, no crazy permissions, no nothing). The app uses real samples, supports sustain pedal, metronome and makes really everything for a low latency.
If someone is interested, I would really love to hear your feedback:
Many, many thanks
