Look up onDoepfer's A-105-2 is a 24dB/oct lowpass filter module featuring the SSI2144 filter chip, a modern descendant of the one used in famous vintage synths like the PPG Wave, Korg MonoPoly, and more. Specializing in juicy filtering, the A-105-2 features a standard control set: Frequency and Q (resonance) knobs, plus attenuators for Frequency CV Input 2, QCV, and Input 1's signal level. Two signal inputs allow you to handily sum two sounds together before entering the filter, while Frequency CV input 1 supports roughly 1V/Oct tracking—ideal for key tracking or self-oscillation usage.
