I worked at the Radio Reading Services of Cincinnati in thenineties when
they had a huge mixing board which was about 6 feet long. Sitting on top of
this console was a thing called an auto level which was made by a place
called Science for the Blind and when I knew about them in the late sixties
and early 70s, they were located in haviford, Pennsylvania. This Auto Level
buzzed once your peak levels had been reached and had Braille on it.
I wonder if thisScience for the Blind is still around?
Thanks for thename of this book? How did you read it? Was it pdf or Braille
or what?

Subject: [ddots-l] Mackie mixers
Hi Folks,
I was out of town and just returned to catch up on postings about Mackie mixers. A really good book that covers many of them including all the ones mentioned in the posts is:
Mackie Compact Mixers by Rudy Trubitt.
It is good at not only explaining the workings of Mackie mixers but also mixers in general. Additionally, I've written to him at his web site and he wrote back thanking my for compliments about his book and said I should write back if I had questions.
His web site is at:

Also, Mackie is located just North of where I live in Seattle. One woman who is a key player in web accessibility lives here in Seattle and her husband works there. If folks aren't getting accessible pdfs from them I could pass along requests through her. [She is out on maternity leave at the moment so that might take a month or two.]
As a sighted user I can see that one major inaccessible aspect of their mixers is in the line level set up instruction. It has you set a few buttons and watch for the LED lights to be at a certain level.
This too touches upon that other person's post about tuners with their visual cue for being in tune.
Perhaps the workaround for each of these is some sensor that would sit atop the desired led light and then audibly chime to indicate that it has been reached.
My Korg guitar tuner has not only a needle meter but also a two red triangle lights to indicate sharp or flat. Other tuners I've used have multi-color schemes.
If the manufacturer can send a signal to a light when a note is sharp, flat, or on pitch (or too high in the case of a peak meter) then that same signal could be routed to something else. I'd imagine the best solution for the tuner would be an earphone output jack so that the tone wouldn't interfere with tuning.
