This is a video i made for the Crack & Shine project.
The book and the films for this project are dope.

The answer is very simple! We used a VCA Mixer. Specifically the Vestax PMC-07 Pro. Because you know… we’re pro like that.
Well, I’m glad you asked. Allow me to explain: VCA or Voltage Controlled Amplifier means that instead of sending the audio signal to the crossfader the mixer instead sends a voltage which in turn controls the volume level for each channel. This makes determining the position of the fader very easy; simply measure the voltage for each channel.
Because we’re so damn pro and didn’t have any of the parts to make a proper Y cable we just soldered everything to the crossfader.
The Arduino sketch we used can be found here.
In summation here is a list of items you must procure to do this:
Build your Y cable. Make a couple voltage dividers. Hook it up like the picture above and BLAMO!
#Pro-Tip: Elliot Marx informed me that if you use an Innofader (the origional, not the Pro or PNP) it will limit the VCA voltages of the PMC-07 Pro to 5V eliminating the need for the voltage dividers. Wire colors for the Innofader are as follows:
Blue = 5V
Green = VCA1 (varies from 0 to 5 volts)
Yellow = VCA2 (varies from 5 to 0 volts, moves opposite from VCA1)
Grey = ground
Thank you Elliot!
We know what the white girls say, and what flute players say, and even what black guys say to pregnant girls. But what don’t you know who said what to whom? Has anyone said this shit?
