go slow, my guy.
experiment.
start with a blank DVCO synthesis page.
vary the oscillator configurations and note the basic sound characteristics that each configuration makes.
find one that is pleasing to you and dive in.
change the decay time of each oscillator, as well as their respective tune/detune parameters.
consider the levels of the two oscillators and attenuate or boost using balance. in combination with the decay of each oscillator you can get some nice over articulated or soft transients from one of the oscillators.
the filter is extremely important to coax a good sound out of it imo. slap a pk filter on it with some resonance.
edit:the BEND parameter i believe is what you’re looking for; +values for a more stabby attack. this in conjunction with a pk filter with a low freq cutoff value and a generous amount resonance and overdrive should get you an m-80 in a tub.
try some overdrive.
note/save any sort of settings you have.
repeat the process detailed above.
come back to your saved patches and tweak them some more.
