Glad to know people are using this.
The one-liner giso suggests is correct. fast_coefficient_to_dB is good
enough for the
I have the fix for this in my private tree that I will push up,
regrettably I had incorporated another fix for an obscure problem with
dynamic USB numbering that doesn't work (yet), and there appears to be a
problem with certain tranzport keystrokes in later versions of ardour
that I haven't nailed yet, either.
It may be merely that my tranzport has gone south. Let me know how
