Not sure where to post this but I've plumped for here -
I've just patched a trigger to front layering system for 4 videoplane objects inside M4L.
The patch keeps a record of which track resides on which layer and every time a track is muted or unmuted it adjusts the values.
I think I've got it working right but surely there is an easier way?
And surely this is something that's been done before many times - couldn't find it anywhere though - maybe I wasn't using the correct search terms?
