The Nucleus exciter will indeed pass audio. However the only audio path deals with what would be called VCO Modulation (VCO MOD). It's missing the other path called Reference Modulation. The REF MOD is needed for the low frequencies (DPL and some PL) because the synthesizer and VCO will try to corr...
