I believe this app could be recognized as a better general player
which has many advantages over other players which does not have score.
But real intent of this app is to provide more than 'player'.
Wished this app. to be a good supporting friend for instrument practice,
playing together with 'my' tempo and volume, and have fun with various
instruments for accompaniment. Also, score generated gives you much
convenience for sightseeing, setting start and end point for repeat, and so on
though this score is not enough to be replaced with sheet music.
So, people may practice instrument, still looking at his/her own sheet music score,
while listening this player with earphone on only one of his/her ear to listen both
instrument sound and this player's other parts playing.
