Additional method of specifying key signature

Hi,

I posted this question to the forum a few days ago: https://opusmodus.com/forums/topic/3886-incorrect-pitch-notation-for-minor-key-in-def-score/#comment-13346. The main issue was that OM was respelling my accidentals when I rendered my score with def-score and set the key-signature to '(d minor). For example it was rendering cs4 as db4, etc. I partially solved the problem by setting the key-signature to 'chromatic or 'atonal. Now all the accidentals are rendered correctly as per my OMN. What's missing is that my score does not have a b-flat in the key signature.

My suggestion: Allow the key-signature parameter in def-score to specify a custom key-signature such that the OMN rendered in the is not respelled as per a common key signature. This could also allow composers to render uncommon key signatures like those found in some Bartok scores, like just having a b-flat and a-flat with no e-flat. I imagine it could look something like:
:key-signature '(bb ab), or ('bb fs) to combine sharps and flats.

OM is by far the most powerful software available for algorithmic composition, but I, maybe others, have gotten pretty quick with writing raw OMN to sketch out music I've written on paper or otherwise. In many cases, it can be a more efficient and ergonomic way of entering music than tools like Sibelius which often require switching between a mouse, keyboard (computer or musical).

Thanks for taking the time to read this.
