Okay, thanks for this info.

Really, my question isn't about the implementation. I am asking about OSC
protocol best design practices, in general. This is not Jackbeat specific at all
to me.

What about the in/out symmetry that I mentioned? Should the track position go
into the path or be passed as a value? Should indexes be zero-based? Etc..

To be honest, I am very confused about the idea that OSC is some kind of MIDI
successor. The MIDI protocol is a rather defined, with notes, CC, etc..

Whereas OSC just looks like a generic RPC mechanism, thus requiring some
development knowledge or custom-made tools.
