I know, it sounds like the easiest thing in the world to do but I've had not been completely happy for a long time. I've been stuck in the it-has-to-be-done-with-unison-and-of-course-both-OSCs-detuned-mood but it turns out I found the solution in slow pulse width modulation with only Osc 1 (!)
Does anyone have an even more 80s sounding 80s bass, please discuss and share (preferably an mp3 sample)?
