The Simple LFO is a… simple LFO module for your Eurorack system.
Two waveforms available: Triangle and Square wave. Configurable amplitude and Low/High range switch.
It’s easy to build, easy to understand and maintain. Only easy-to-find through hole components.
- Corrected an inversion in the LED circuitry, which prevented the LED to lit as expected.
About the BOM
Many component values are not critical in the Simple LFO. It’s a robust circuit which can tolerate many experiments and modifications of the values.
The 2 input capacitors C5 and C6 can have any value between 1µF and 100µF. A common value is 10µF. One important thing is the minimal operating voltage of C5 and C6: it mustn’t go below 25V.
