Realise that this thread is a bit old, but I accidentally came up with a half decent deep house bass patch by having osc1 as a sine (down one octave), osc2 as saw (right down), sync 1>2 on , both filter and amp envs with no attack and around 40% decay, no sustain or release, lowpass filter at 50 with resonance of 25, then analog boost at 70% and onion overdrive with mix at 100% tone & hicut set to 0% and drive at 50%, then a comb filter with mix at 100%, reso at 50 and frequency at c#5, delay at 1/6 clock and reverb in large room, let you decide the feedback, levels etc..
hope this helps
