Description
copy from https://steffcorp.se/product/2612/
This is a clone of the 4012 VCF used in the ARP 2600.
Other than some substituted parts and a “sandwich-layout” mainly adjusted for the eurorack standard, I have tried to keep all the original quirks as close to the original as possible.
The “sandwich-layout” simply means the VCF is split in 2x PCB’s mounted in parallel on top of each other.
The Core-PCB contains the main circuit, while the Control-PCB contains the controlling elements as well as the buffers.
See the Build-Document for more detailed info/options regarding the build.
