Audio to CV

Hi guys,

Aliensolo is an awesome pitch tracking VST synth which uses audio as an input to create sweet sweet basslines. Similar to ‘the mouth’ by tim exile. I want to input audio into my analogue synth to achieve similar results… so I am presuming that in order to input audio and have it control the synth I have to convert the audio into a control voltage as there are CV inputs for gate, envelope, pitch, and filter… my question to you guys is: is there a single unit which I can buy which does this? Like, a magical little box which takes an audio input, does some magic, and spits out CV outs for pitch and envelope? Thanks guys.
