This module is part of my Eurorack series. It is a low frequency oscillator (LFO) with an adjustable frequency range. The output level can be changed and blended between triangle and square signal.
There is a potentiometer to control the LFO’s frequency. It is generating a triangle and a square signal and the output can be blended seamlessly between both signals. It can also be attenuated with the level potentiometer. The maximum amplitude of the LFO is 10Vpp (10V peak-to-peak, from -5V to +5V).
