Doepfer A137-2 VC Wave Multiplier II Tutorials by Raul Pena

A-137-2 Wave Multiplier II
Back in August of this year Raul Pena published his series on the Doepfer A-137-1 Wave Multiplier module (11 parts!)

Now he's back with the first tutorial videos starring the follow-up to this module, the A-137-2.
The A-137-2 is another version of a wave multiplier.
In contrast to the A-137-1 Wavemultiplier I the A-137-2 generates four phase-shifted copies of a VCO signal applied to the audio input. The four shifted signals are added to the original signal to obtain a fat sound similar to five independent VCOs.
