KOSMOS LFO6
About the KOSMOS LFO6 PCB
KOSMOS LFO6 is an open source PCB design by DavesKosmoModules, published on GitHub under the CC0-1.0 license. It is a 2-layer board measuring 96.1 × 115 mm, with 105 components from 21 distinct parts.
Other key parts include the LM13700 and TL074. By type, the board carries 53 resistors, 20 capacitors, 14 diodes, 5 ICs, 4 transistors and 2 connectors.
From the project
- 4 Lfo's - Each has a cycle duration between a few seconds and a few minutes, approx 6 sec 12 minutes - Each LFO has it's own speed control - A single global speed control - CV control for the global speed (not 1V/Oct) - Each LFO has both unipolar and bipolar outputs

I have been using the lfo for slow evolving movement of sounds, it is not a replacement for a standard lfo, normal tremolo and vibrato can not be realized with this module.
