02 VCO to Filter

Next we’ll start with the first of our audio connections. Think of your basic Eurorack system as a commercial synth, but all of the elements need to be soldered together. That’s why we use patch cables, so with our cables in hand, make a connection from your VCO or Oscillator Output, to your filter. VCO Outputs are often labelled with icons, like waveform shapes. Start with something like a saw or square wave, as these are rich in harmonics. Filter inputs are normally labelled Input or Audio In, but if in doubt, simply look in the manual.
