Hi All,

Here a small demo of the Polygogo module from E-RM.

Nothing fancy really, just a little demo to discover a bit the weird sounds from Polygogo :-)

Modulation done by Vermona - fourMulator (quad LFO), "filtered" by Instruo - Tràigh and internal Eurorack effect by ACL - VC Dual Delay (just a bit) and added a little touch of external reverb and delay to it as well. That's practically it. Thank you very much for listening and kind regards, Garfield.

Edit: Forgotten to mention the filter that had been mildly used.

That sounds really wild. I'm not sure how I have never stumbled across the Polygogo before. I'm going to look into it a bit deeper.
Thanks for sharing your demo!


Befaco Lich has a patch called Polygonal VCO that is supposedly inspired by the Polygogo. I'm not sure if the two can be compared but I would like to know. :)

There is a demo here:


Hi Farkas,

Yeah crazy module it is ;-) It had been announced early 2019 and since early 2020 it's available, at least here in Germany, I got mine from Schneidersladen. Here is a link from a demo, introduction & explanation of the Polygogo by the creator of this module from E-RM in Schneidersladen on YouTube in English:

Now I need to somehow nicely ingrate it within an interesting patch ;-) Kind regards, Garfield.

Edit: Removed typo.

Hi Chinpira,

Yes indeed, the Befaco - Litch looks from a functionality point of view a bit like the Polygogo or at least they certainly have some similarities. Obviously the screen is missing with the Litch. The Litch, at least in that demo you provided here, it is MIDI driven, which is not my preference, I rather have direct controls. On the other hand the Litch can produce some real crazy sounds too! :-) I guess for someone who doesn't mind to use MIDI, the Litch is indeed an alternative to consider.

Kind regards, Garfield.
