This is mostly accessible, and it Works from startup.

VoiceOver Performance

VoiceOver reads all page elements.

Button Labeling

Most buttons are clearly labeled.


There are some minor accessibility issues with this app, but they are easy to deal with.

Other Comments

There is some distortion in the sounds, and if there are volume controls I can't find them. The buttons that represent the channels in the mixer view are not labeled and could be knobs for all I know. All that's needed is to start it up, enable core midi, and go.
