Since 0.15 introduced programmable speaker, I decided to give it a try and implemented basically (mono-style) one of my favourite piano songs: Payon Theme from Ragnarok Online.
This version of song consists of 284 notes. For each not I used a "ROM" cell: 1 Constant Combinator and 1 Decider Combinator. Also there is 1 Arithmetic Combinator for clock and 1 Constant Combinator for starting the cycle. And of course, the Speaker itself.
SCREENSHOTSorry, don't know if it is possible to embed the video, but here is the link: https://www.youtube.com/watch?v=LmY1bp-7Zng
Unfortunately, the speaker does not provide the full scale, so I'm afraid it is not possible to fully implement this song in polyphony.
