Hi:
I would like to make a couple suggestions:
I am a blind user and any app that utilizes sound and also emulates older tech is interesting.
Your app is somewhat accessible using the JAWS screen reader in Windows.
It basically requires reviewing the screen and simulating mouse clicks since the program doesn't appear to support keyboard navigation.
I wonder if you'd consider adding a few keyboard shortcuts useable in the program window. Maybe a keystroke for the various buttons; say alt-O for options, alt-D for drive ambiance, etc. Also, the sliders do not seem to be adjustable using the keyboard, but, I may not have hit the right keys, so I'm not sure.
Anyway, this is an interesting program.
Thanks for writing it.
