A-121d Doepfer Eurorack

Dual multimode filter

(Superbooth 2024)

Filter 1 works here as a band and high pass, while filter 2 offers band and low pass.

The module works in parallel or serial operation, so it can also be used for stereo operations. Interestingly, there are no separate potentiometers for each filter. The big frequency and delta (distance between the two frequencies) control both filters at the same time.

It also offers a simple mixer unit with two inputs and a mix output. If the sockets Mx1 and Mx2 are not connected, the inputs are normalized with the bandpasses. All other filter combinations are implemented by patching the filter outputs with the mix unit.

On the connection side, it has dedicated inputs, and outputs for filters plus CV control over the frequency and Q.
