In this signal chain we have an Auto-wah patch via the Hex Envelope Follower controlling the Hex VCF's filter frequency and resonance. This is recorded into 6 channels in a DAW, each one running an amplifier simulator VST. One of the significant advantages of building an Auto-wah circuit with the Hex EF in polyphony is much more accurate activation with adjacent string noise and resonance not activating the envelope follower as it would in a common mono Auto-wah guitar pedal. This has dramatic advantages in quickly played phrases and guitar leads.
