I just wanted to say thank you for this. I have been tuning modular oscillators for years and without realising it I have been aiming for just tuning. It so nice to have this in Ableton now. Thanks!!

The buttons to load the CSV, SCALA, and KBM do not work in my version of Live 11.0.12. You can go in and swap them for simple Live.Button and it works. It's something with the label not sending out a bang.
