Part 2 in the running series on my Project XII DIY modular analogue synth and I build and play the AS3340 1v/octave Voltage Controlled Oscillator (VCO). The AS3340 is a clone of the original Curtis chip found in 1980s synths. I have built the circuit from the easy to follow instructions on the Look Mum No Computer website [ Ссылка ] If you want to hear Sam's demo check this out [ Ссылка ]
