Cool!
That was fun! In fact I thought of that a year ago, trying to record the flute notes and put them into flash. I ran out of time and gave it up. So it is nice to see this!!
I tried playing the Twinkle Park music from sonic advanture. it worked! One thing is a little bad is that the music sounds get delayed , and it is impossible to play fast music.
but anyway that's a bice job!
