432 or almost anything you can imagine will shortly be here for mg3hex using lofileif’s add on:
it seems in theory that adding this feature to mg3 native would not be that complicated (speaking as an outsider/non-coder).
otoh, all the machine learning was performed on 440-tuned guitars, which might not translate to 432.
you’d probably have to get a dozen like-minded guitarists on board in order to get jamo to consider adding this feature, assuming it is possible.
having experimented with 432 myself, i wouldn’t put it on my feature request list.
