Erica Synths lets you go crazy with DIY modules SWAMP and Multimode VCF - gearnews.com

gearnews.com

Erica Synths' DIY Swamp and Multimode VCF modules offer a wild ride for synth enthusiasts eager to dabble in DIY projects. The Swamp module stands out with its ability to generate chaotic CV and audio randomness, appealing to those who thrive on unpredictability. With features like random audio frequency outputs and a quirky ring mod, it's an experimental dream. Meanwhile, the Multimode VCF, crafted around a custom chip, promises versatile filtering with simultaneous LP, BP, and HP outputs. However, the DIY nature of these kits means assembly is required, which might deter less hands-on users. While these modules promise excitement, the commitment to building them could be a hurdle for some.
