Mixer8 mute/solo randomize/initialize behavior seems wrong

[RareBreeds]

The Mixer8 solo and mute buttons don't update their visual state when right clicking and selecting Initialize or Randomize.

The solo and mute values used for audio processing do update, which you can hear and also see by hovering the mouse over the buttons. However, when randomized, they are updated as random floating point values between 0 and 1 which makes them behave as a volume control rather than on/off button.

I'm using a build from source on macOS - d482868

Wow, I didn't think anyone used Mixer8 since Mind Meld come out!
