Emulate The West Coast
Start with a dual complex oscillator – a module with two oscillators that can modulate each other to create a range of FM and AM sounds alongside oscillator sync and sometimes even additional waveshaping too. This is where you can generate a huge range of unique and complex tones not heard in many other synths. You’ll want a low-pass gate (LPG) to control the high-end frequencies and amplitude in your signal. Patch in your gates and triggers to the LPG to open the sound and let the vactrol ring in with its natural sounding decay. A good place to start is with Make Noise, Sputnik Modular and Verbos Electronics.
