It's not exactly easy to make an "accessible" DAW. Especially not when you consider that there probably isn't a huge market of blind music producers relative to the amount of work it would take to, say, make a somewhat-sane interface for a screen reader for a program as complex as ableton. The interface is very complex as is, and would almost certainly require some re-jiggering before it would work well. I doubt enough people would buy t to ever make it a worth-while investment.

There it is, thread complete
