I posted this on Gearslutz but since I want everyone to make the best music possible I'll post it here too
The best bass I've been able to get out of the A4 without dealing with the resonance issue is...
Oscillator 1 filter feedback type, loud . filter 1 @ 40-45 and filter 2 (lopass 2) at 20-30 or so.(gotta find the sweet spot) The strange thing is not having any resonance on either filter and overdrive needs to be at 0 too. Filter 1 EG depth and EG shape to taste.
This way you don't need to wait for the filter resonance to saturate.
