Here’s my in depth run down of the Erica Synths Graphic VCO. It’s a eurorack module that packs in a nice interface for controlling wavetables, on board waveform drawing and design, tuneable and shapeable sub generator and output, loads of onboard FX including FM, Ring Modulation, Phase Distortion, Bitcrush / Downsample, Distortion, Wave Folding and Wave Wrapping. There’s loads to go at so check out the timing description below and skip around to see the bits of the video you’d like to check out.
