Tempo Changes plugin improvement
I've created a version of the Tempo Change plugin that gives some new power, so to speak (the changes are very small). The extant plugin provides a linear staging of the tempo difference, let's call that x, which varies from 0 to 1 over the interval (then multiplied by the tempo difference).
My change allows any real power of x. I find that 2.5 gives an effect quite more pleasing than the current 1.0. Don't laugh until you've tried it (you can make such a change without the UI in one line after studying the code). You might want different values at different times (I have a dialog slot), or start the deceleration at different points back (in conjunction with finding the best exponent).
Sample of 2.5 (at both double-bars in the first (I) and last (V) canons): https://musescore.com/bsg/scores/5571862 .
Then answer as to whether or not this is useful.
