6HP Voltage Controlled Oscillator

The ASol VCO 6HP is a single VCO laid out in a similar way to the VCO section you would find on a monosynth. It has outputs for sawtooth and pulse waves (pulse wave has its own volume knob).

According to the documentation, The VCO can go down to low frequencies so it can be used as an LFO.
