My code is not set up to handle B# as a valid chord I believe, so that's something that would have to change, but it definitely creates a lot of annoying problems, as it's still not clear to me when I would use B# versus C in all situations.

Hi Mike, it's just my 2c worth, but I wouldn't necessarily do that.

While erhe is technically correct (and I agree with much of what they have presented), it's my observation that such constructs usually aren't helpful to someone sight reading, or otherwise not very familiar with, a piece.  This is especially true for weekend warriors.

Where the enharmonic equivalent is a sharp or flat (E.G. C# instead of Db or vice versa) then it usually makes little practical difference for the player whereas B# instead of C, or Fb instead of E etc. commonly takes more time to process and can thus more strongly impact the flow of a performance*.  Of course this isn't necessarily true of every player as some are more analytical than others, yet ease of interpretation usually equates to a faster response.

You are not going to be able to please everyone.  It seems to me the best choice is to please the majority as well as you can.
