Wasn't sure how useful this would be to me, but it could become an essential. I do a lot of remixing & like to be sent midi files rather than just audio to work with. Dropping a new midi file into Logic & setting up plug-ins for each instrument takes a long time, especially if I am only going to eventually use just one track. This is going to be a really quick way to audition those files.

A really useful feature would be the ability to export a new midi file from Rondo which would remove any of the midi tracks that have been muted.
