Sponsorship available for makam.ly transposition issues

[Adam Good]

Hi everyone!
I'm assuming no one is currently working on the current issues involving
transposition when using makam.ly ... if so please be in touch with me.
Otherwise, would anyone be willing to work on it? I'm MORE than happy to
sponsor as it's completely out of my league technically.

Notation of Turkish makam music uses a microtonal system of 9 microtonal
commas to a whole step which makes transposition tricky no matter what.

Below is a short example of transposition failure. When transposing down a
fourth we get errors on bfc and bfb pitches.

Hope to hear from someone!
best,
Adam Good
