Dual SH101 Sub-Oscillator
Square wave sub-oscillator
This Sub Oscillator tracks an oscillator signal from a VCO and generates a square wave at -1 or -2 octaves below. Works best with sawtooth, triangle, Sinus waveforms or simple square waves.
There’s a pot that mixes between the 2 sub-octaves and if you set it to 50% it sounds just like the famous Roland SH-101 pulse sub-oscillator.
For this to work, you need to route the oscillator output of your synth into the sub-oscillator Input. Then you get the sub-oscillator signal at the output. Mix it back with the original through an audio input chanel to enjoy that juicy low end.
Available as solo or dual sub-oscillator, assembled, as full or partial kit.
