Hello, /r/blind! I'm a sighted music professor, and I'm working to try to make my online utility, $1, as functional for as many users as possible. Though the utility is designed primarily to allow sighted music teachers to create, edit, and use braille music scores, it seems like a no-brainer to make the utility work well with assistive devices.

Anyway, the utility has a spreadsheet-style interface, and it is currently configured to send information about the currently selected braille cell to the screenreader. The information is descriptive: something like "Line 2, character 4: E quarter note."

For braille display users, I have a switch which instead sends the entire current line of braille. I don't have a refreshable braille display, but I have things working somewhat using Mac OS X VoiceOver's virtual braille display.

So my question is this: do any of you use text-to-speech and braille displays simultaneously? If so, are you aware of any programs that send one thing to text-to-speech and something else to the braille display? When my utility is in braille display mode, the entire line is also read by the text-to-speech software, which — since it's braille music — doesn't make a lot of sense. My utility uses ARIA tags to do this, and it doesn't look like ARIA has much control over it; my hunch is that the limitation is deeper in the system software than that.

Anyway, I appreciate any insight any of you can provide. Thanks so much for your help!
