Hi For those interested, I've just add, on request, a new micro-tonal tuning mode to gxtuner. Shruti, which is the Indian non-equal tuning ratio to 22 semi tones. You can get it here: https://github.com/brummer10/gxtuner to use the new shruti mode, you must start gxtuner with the parameter -m shruti |gxtuner -m shruti |
