Doepfer modules, and your thorough explanation of them, never cease to amaze me. I don't pretend to understand even half of all that, but I liked it.

[@RossKingston]

this was my first module when i started.
i now have 2 of them ;)

You started with a PLL? :) What nerdy initial setup, I like!

[@MirlitronOne]

Best info / demo video on this interesting and enigmatic module, thanks.

[@petersirca223]

Thank you very much! Finally I am beginning to understand what a PLL is and I can foresee a time when my eyes will not glaze over everytime I see it :)

Random voltage > A-136 > A-196 offset, with a really high frequency triangle or saw wave into the Signal In on the A-196 is a great, super tweakable source of random splutter.

This is the best explination of a PLL I have ever witnessed. Thank you 🤌

super Video! Ich werde mich gleich mit meinem A 196 PLL befassen 😎

cool

Very good explanation of this rather interesting module. I started looking for PLL modules from other manufacturers, but could only find the now discontinued "WMD Synchrodyne" and wonder why...
Wouldn't this behavior basically also be emulable by mixing (pitch + (-1*pitch-CV + short envelope + little bit of randomness) on one of the used oscillators?

[@synthesizer83]

The difference will be the missing phase synchronisation. The PLL syncs the phases of the VCOs (when it doesn't fail), which gives a distinct audio impression. Also the glitches are different than just using noise for the cv. Actually, when you have a VCO with soft (or weak) sync, there is a PLL involved. Patching it with the extra PLL is quite nerdy, I guess thats the reason why there are so few PLL modules.

[@Waldemar_la_Tendresse]

@@synthesizer83 I see your point, but I have been talking about the phase, when pitch just changed and the PLL unit tries to sync to the new pitch, since
new pitch = different phase length.
