transcribe

Well, you can go to sheet music if you want to but there are plenty of packages out there that will display midi files as sheet music so that would seem to be an unnecessary complication. The core problem is polyphonic music -> midi and that is hard enough! I will take a look at your software, it definitely sounds interesting, the question at the end of https://github.com/sevagh/transcribe/blob/master/doc/snac.md can be answered in the affirmative, the Onsets and Frames package mentioned elsewhere in this thread does just that and works very well. By the way, the linked paper is unavailable.

Interesting project. What do you think of https://github.com/sevagh/transcribe ? It seems like in your project the word transcription isn't referring to sheet music transcription?
