The "VCO F socket" is a CV input for the VCO pitch. It's not a typical audio
 input but of course you may connect an audio signal an modulate the VCO with
 the audio signal if you want (e.g. FM from another VCO or "noisy" VCO).
 Everything is possible in the modular world :-)
 The function of this socket is described in detail on page 13 of the Dark
 Energy user's manual.
