I have no suggestion but a question:

Given that an actual performance mostly differs on the tempo level, not on the relative note length level (a quarter is still a quarter, but just with a bit more time) wouldn't this be a search for a tool that lets you adjust the tempo track of the midi very easily?

For example something that plays back your audio file and you happily tap along the quarters or so on a midi key or keyboard-key (what has less latency?) and the tool records your tapping as tempo track which can then be used to override the tempo instructions in the original file.

A bit like a conductors tool. I have read of several tools that use this method in the past, but I am unsure if there was a linux one among them.



Nils,
