Electronic Minute No Modular Eurorack Synth Sqr Sequencing

I want you to compare this sound with:"electronic minute no 18 - vcv rack sqr sequencing"https://freesound. Org/people/gis_sweden/sounds/413520/in this sound, no 19, i use my modular synth. The sound is not as clean as in the virtual one. To some extent i blame my method of recording. . . Different oscillators sound different. Here i use a self oscillating filter. That produces a clean sinus wave. The cleanest sinus in my rack. But i guess the real thing is not perfect and that is what you are hearing? in neither of the patches i use a quantizer. . . (that's art :-)and, i almost forgot, i use a cheap analog delay pedal. Noisy. . .
