The only officially licensed remake of the EMS diode lowpass filter used in the VCS3 and AKS synths. It´s a faithful recreation of the original circuit, featuring some modifications that are also done on vintage EMS equipment, like a switchable faster CV response option for very quick modulations. Another switch determines if the filter has -18dB/oct slope as used by EMS pre-1974 or a slope of -24dB as used after 1974.
The cutoff frequency and also the resonance are voltage controllable. Signal inputs and outputs have level controls.
