I have spent the day trying to patch up a phase locked loop (PLL) with building block modules and I thought I’d share!
From my experience it is far easier to patch up than it is to understand the theory behind how it works.
2 x oscillators (best to start with squarish waveforms and work from there)
1 x slew (I used MI Stages in orange mode)
1 x ring modulator
1 x polariser / inverter (not necessary if you invert with MI Blinds, WMD Triple bipolar VCA, Doepfer A-133 etc)
I find the sound to be a great compliment to the primary tone. Depending how the settings are adjusted it can be smooth or savage.
Basic diagram of PLL patch (note invert not needed if using blinds - set small attenuverter to negative)
Good video explanation of how PLL works and is patched up.
