befaco/hexmix-vca

Hexmix VCA

Befaco

Six-channel VCA with variable response curve (exponential through linear to logarithmic), with summed mix output. Can be used as a six-channel mixer or six independent VCAs.769

Capabilities 3

Cascading Mixercascading-mixer
Each channel output is normalled to the mix sum; patching a channel removes it. CH6 doubles as the master mix output.
Mixermixer
All six channel outputs are normalled to a summed mix output at CH6, activated via a Mix switch. Patching any individual channel output removes that channel from the mix.769

CH1 Outputmixed-8V to 8VMain channel output. Normalled to the mix sum; patching a cable here removes CH1 from the mix.769
CH2 Outputmixed-8V to 8VMain channel output. Normalled to the mix sum; patching a cable here removes CH2 from the mix.769
CH3 Outputmixed-8V to 8VMain channel output. Normalled to the mix sum; patching a cable here removes CH3 from the mix.769
CH4 Outputmixed-8V to 8VMain channel output. Normalled to the mix sum; patching a cable here removes CH4 from the mix.769
CH5 Outputmixed-8V to 8VMain channel output. Normalled to the mix sum; patching a cable here removes CH5 from the mix.769
CH6 Outputmixed-8V to 8VMain channel output / master mix output when Mix switch is ON. In mix mode, channel 6 output carries the sum of all six channels.769

CH1 Responseknob—Controls the VCA response curve. Center is linear. Fully CCW is exponential. Fully CW is logarithmic.769

  • Exponential -100–0%VCA follows control signal exponentially; smooths dynamics, useful for modulation sources.769
  • Linear 0–0%VCA follows control signal linearly; preserves natural dynamics of the sound.769
  • Logarithmic 0–100%VCA follows control signal logarithmically; adds strong dynamics with aggressive attack and abrupt decay — good for harsh percussion and audio crossfades.769

CH6 Responseknob—Controls the VCA response curve. Center is linear. Fully CCW is exponential. Fully CW is logarithmic.769
CH6 Volumeknob—769
Mix Switchswitch—When ON, sums all six channels and routes the mix to the CH6 output. When OFF, mixing is disabled and channel 6 acts as a standalone VCA (useful when connected to the Hexmix via the expansion port).769
