Performance Collaboration Tool

I'm posting here to see if there would be any people interested in helping test out a web application I've been developing. The application is geared towards several different groups of musicians - composers/arrangers, students and teachers. It lets users post songs, either composed within the software using a very basic notation program or by uploading MusicXML files. The community can then perform and record the individual parts, uploading each of them so that they can be combined into a sort of "virtual ensemble" mix. Because the software plays the accompaniment track, the various performances are kept in sync. There's also a gaming aspect to this where the software listens to the performer and scores him/her based on how many notes are played correctly.

To begin with, I'm hoping to get some people to add shorter, simpler pieces, under 4 minutes. Some small ensemble pieces would be great to try. When posting music, you can sync an mp3 accompaniment track that you've created with external software. The app also has a built in set of (not fancy) GM sounds. One nice thing about building performances is that you can mix your existing MP3 accompaniment with whatever instrument parts people have recorded. I've always found this is a nice way to fill out a mock-up when I can't get all of the parts performed.

I'll mention right now that my application still has some big limitations. The mixer/sequencer isn't fancy, but you can at least save out mp3's of tracks if you'd rather take the performances into a full-featured sequencer. The notation engine is still basic as well, with many things not supported (no hairpins, articulations, repeats, etc.). I've been primarily trying to get this up to a level that's appropriate for students to have fun practicing and composing, but I think it could be useful for a community of composers like this as well.

The current (beta) version of my app is at http://www.odogy.com. It would be really fun to build up a little group of performers and composers to help make recordings for each other. I can contribute on euphonium and recorder.

Thanks!
