access to WaoN project looks increasing thesedays.
I don't know anything is happening, though...
By the way, I found another package for AUR. (See here for other packages.)
PS. I also found yet another
package for GNU-Darwin.
I also find a thread in some ML by Google:"Re: [LAU] Voice to MIDI" @Linux Audio ML
but I couldn't get the "Top of the World" midi file (it's already gone?).
