Using a Piano Hat .
On the .wav file of drums, there are eight different sounds. Once it plays, there are only five sounds that works. Perhaps, the software might be an issue.
Tested all .wav files by typing aplay /home/pi/Pimoroni/pianohat/examples/sounds/drums/ (.wav)… on terminal app. All of them are working. Clap, crash,hat, hit, and rim are responded. Smash, thud, and ting are not responded. What it can get fixed?
PS Thanks Pimoroni for creating awesome Piano Hat.
