RE: Different accidentals for same pitch bend?

[Richard Sabey]

Keith,

Thank you for your message. Your suggestion of ly:set-default-scale, together with ly:make-scale, turned out to do just what I wanted. That showed me what to Google for, and that gave me the info I needed.

Yes, I saw that discussion as a result of Googling, and I tried his code, but unfortunately I couldn't get it to work on v.2.13.62. Never mind, I now have something which does what I want.
