As I wait for my new Doepfer monster base case to arrive, I am looking at a new complex analog oscillator to spice up my setups. Considering Instruo CS-l, Verbos Complex Oscillator, Frap Tools Brenso, Endorphin.es Furthrr and Rossum Trident. Also looking for a good filter to complement them. Thoughts? I plan to pair it with Hertz Donut that I want for FM stuff. Add in some drums and I am golden.
