I just released Version 1.4.0 (and 1.4.1 directly after that) with JF support to GitHub. Update via the maiden project manager, git pull, or download here.
For JF I added the same possibilities as for Crow’s CV2 (previously named “alternative CV”). The method for note calculation, a note offset, and an octave offset can be configured in the parameters menu. JF note output is off by default, so you will have to activate it in the parameters menu. You may have to change the setting for the ii pullup, depending on your configuration (default is on).
