Takaab VLH from Siam Modular (VCO's Little Helper)

Note: we made a editing error in this video, so we uploaded a new correctly labelled one here:

Designed in collaboration with journalist and musician Steve O'Hear, VCO’s Little Helper is a eurorack module that supercharges your existing oscillators by adding a ring mod, sub and noise - three classic features found in the VCO section of numerous vintage synthesizers from the 70s and early 80s.

Specifically, we set ourselves the challenge of designing a great sounding ring modulator, coupled with two ‘sub oscillators’ (frequency dividers) and a noise generator, all packaged into a module small enough to demand room in any eurorack case.

Tired of shelling out for stackable cables or using up precious case real-estate to add yet another multiple module to our systems, we also wanted to include A and B outs (acting as something akin to a ‘thru’). That way it is easy to re-use your VCOs elsewhere in a patch without having to first un-patch the VLH.

At just 2hp in size, the resulting all-analog design has A and B inputs (intended to receive up to two VCOs), ring mod (A carrier/B modulator), sub1 (A -1 octave), sub2 (B -2 octaves), noise, and A and B outs.
