I still have received no response from Hugo or Rob so I will just let this run for a week or so. They are probably busy doing other more important stuff (like release 2.0

).
Really, the ball is in their court. If nothing comes of this I will still be interested in doing my own tuner (of course this may not work real well with the current player software) . It may not necessarily be based on the Microtune module though.
One other option (dare I say it) is to reverse engineer the current one. But I really don't want to offside anyone so I hate that idea a fair amount.
