Yesterday I tried for the first time to run an external sound source through the Moog Mother 32 Ladder filter. I was rather impressed with the results which I recorded. Closed down the filter has a lovely woolliness to it but opened up theres a quality to it that really shimmers. The wavetable oscillator does not sound like this running through any other of my eurorack filters.
Reminds me of the fun I had processing external audio through my Korg MS-20 many, many moons ago.
