CubuSynth - Dual Vintage VCA

Key features

- Level Knob per channel (offset)
- CV input with Attenuator
- CV input is normalized from channel 1 to 2
- second CV input for amplitude modulation, without attenuator
- Full Volume with 5V, higher voltage amplifies more

The CubuSynth Dual Vintage VCA is a nice sounding, zero bleed, analog Voltage controlled amplifier based on the LM13700 Dual OTA. It can work as two independent VCAs or as a stereo unit, and CV input 1 on channel 1 is normalized to the CV input 1 on channel 2. (same signal can control both Channels)
The Original concept is designed by Tom Wiltshire aka "Electric Druid". [more info]
