So, I was doing a lot of work on my super-sexy composition for the semester, and I was pretty much done, exported the audio (WAV) file from Sibelius and uploaded it to SoundCloud, then promptly lost my USB that held all of my work on it. I have downloaded the WAV from SoundCloud and am trying to work from that, but it's not easy at all.
I had the idea of reopening the file in Sibelius and finishing it off from there, but Sibelius can't open WAV files; the only sound file it can open is MIDI. Knowing the fundamental differences between WAV and MIDI, would anyone know of a way of converting my WAV file into a MIDI file? It would make my life infinitely easier.
