Synthesizer with 3 ic 555. 2 for multy LFO and one as Oscillator. You can use before the 555 oscilator one simole mix with 2 pot to mix the voltage signal from 2 LFOs. Also you can uae only one awitch on/on to.select the LFO signal. Only one per time.i used one resistor and capacitor per lfo out for beter cycle signal
