This app is very nice looking but I have trouble with the audio. The note pressed sounds less than 50% of the time. The mix of the audio and visual (green/red bar) cues is worse than just the visual confirmation so I turn the sound off, but would like to see this issue fixed. Also Id like a wrong answer to give bad sound, possibly a detuned key, but this should be optional if available.
