Voltage controlled low frequency oscillator by Yves Usson ,details on the construction on his page : http://yusynth.net/Modular/index_en.html ,from there : This module is a very useful utilty module in a modular synthesizer. It provides low frequency signals with different waveshapes that can be used to modulate and control many other modules. Another interesting feature of such a module is that its oscillation rate can be controlled by a CV. In this version, the frequency can be set with the RATE knob between 0.1Hz (10s repetition rate) and 100Hz (0.01s repetition rate) or between 0.01Hz (100s rate) and 10 Hz, depending on the rate switch. The frequency can be modulated in an exponential manner using the FM socket, the FM level knob let us control the amount of modulation.
