I bough a Plankton Electronics Spice VCF from a guy in Spain called Guillermo Cantalapiedra. I was told the module worked as expected and no info of any faults or that it was a DIY. When I got the package I quickly installed the module and tried it out. Almost immediately I noticed that something was wrong because the resonance knob didn’t work. I tried a couple of different sound sources, waveforms and pitches, but still no change in sound when turning the knob from max to min. I then shut everything off and pulled out the module. Upon inspection I could see this was a DIY, and a really bad one. Probably one of the worst I’ve seen. Obviously that is why the module is not working properly. I reached out and the seller told me ”I’m using it wrong” and that the resonance has to be CV controlled. He also denied that the module is a DIY. The case has been escalated at PayPal but I’m not sure it will be solved amicably since the seller first refused to take the module back and then wants me to send it without paying me back first.


Just got a reply from Plankton Electronics:

”this is a DIY unit.

  1. There is no serial number (look at the white box it is blank, we write there the S/N manually).

  2. Some soldering paths are not professional, we don't offer that quality.

  3. One of the headers is melted. We will never sell that.

  4. The red strip box is painted bad (we always cover it all)

  5. Guillermo Cantalapiedra was one of the bakers of the Kickstarter campaign on 2019. He pledged for the 3 modules DIY kit.

I'm sorry if he sold you something that is not what he claims it is.”

Adding more photos for reference.

The seller calls himself "gcanta" on Modular Grid.
