Max audio to CV

    Aug 15 2020 | 10:06 pm
    I would like to ask you about the following idea.
    Is there a way to turn my MacBook audio output into two CV outputs for external analogue gear (e.g. by sending it [sig~] value)? Won't it fry my synth (eurorack-format Behringer Neutron)?
    I know that laptop's socket is AC, not DC and I did some research about SE modules or DC-coupled amps, but I still wonder if with [sig~] object this could work even in a limited way( without checking it and risking my synth damage).
    Thank you!

      any analog AC signal can be converted to DC voltage. Simplest using rectifying diode and capacitor / resistor, but output voltage would defnitely be lower than needed. And one would use cycle~ set to 100 - 200 Hz, not sig~ Output might vary from MacBook to MacBook on 2008 MacBook pro max 0 - 2.36 v DC can be output in this simple way.
      Adding electronic to increase this voltage range would end up more complicated, than using some arduino controlled solutions.
