Custom key signatures are currently visual only. They are not understood, therefor don't influence playback, nor are taken into account for courtesy accidentals.

I can see how that would cause the issue I described, but I don't understand what you mean about playback. Custom key signatures are observed when notes are entered, and when you add a custom key signature to an existing measure, notes following it have their accidentals updated appropriately. Since the notes have the appropriate accidentals, they play back as expected.

  1. Jeetee said the linked issue did not mention courtesy accidentals and an amendment or new issue would be needed, preferably the new Issue.

  2. Your comments are unrelated to the issue Jeetee linked to. To add a key signature of any kind to a singe staff, press ctrl (Mac cmd) while applying the key signature. This works no matter which method you are using to apply the key signature.
