Vactrol-based multimode filter based on a schematic by Nyle Steiner. Separate inputs for lowpass, bandpass and highpass.
This filter's unique feature is that different filter types are realized by injecting the audio signal at different points of the circuit. For this reason the A-101-1 has three inputs with level control: one lowpasss input which is normalized to the bandpass input, which itself is normalized to the highpass input. The level controls make it possible to mix the filters and to generate new filter types. e.g. with all three filter levels turned to maximum level you get a notch filter.
Furthermore the cutoff frequency influences which filter type is "monitored". This way you can blend from LP over BP to HP with increasing cutoff, known as "frequency scanning". Interesting effects happen when three different audio signals are used because they are both morphed and filtered at the same time.

WIth a long trajectory building synths, MIDI keyboards and designing bespoke devices for music pioneers Kraftwerk, Dieter Doepfer decided to design his own modular synthesizer in 1995 based on existing electrical and mechanical specifications of lab equipment he used during his years at university. The official presentation of the system at 1996 Frankfurt Musikmesse caught everyone by surprise and created lots of interest. After Doepfer published the specifications on his website, many instrument designers and engineers saw the potential of the new Eurorack format. Doepfer continues expanding their catalog of over 200 modules (and counting), operating from their modest offices in the outskirts of Munich.
