Hi list,

I'm happy to present my first external named [m2f_vst].

It calculates midi note to frequency (Hz), just like [mtof], but with a
variable semitone to whole tone ratio. That means it makes it possible to
play in temperaments 31 (ratio 3:5) and 19 (ratio: 2:3) equal division, as
well as 12 (1:2), 5 (0:1), 7 (1:1) and everything in  between.

To be able to use it as intended it's, except for ratio "0.5" that makes it
work similar to [mtof], necessary to set a modulation index, where 0 is
default (C-C#-D-Eb-E-F-F#-G-G#-A-Bb-B). Changing the value for "mod"
replaces one note for another (for example G# for Ab) for every "+1" or
"-1" in the circle of fifths up by increasing and down by decreasing.

Documentation is provided in the manual/ folder. An example patch that
plays a part of J.S. Bach's prelude of the 5th English Suite is provided in
the examples/ folder.
