in this track I used only a tb-303 as synth, but I routed the signal through several effects: zoom reverb korg ea-1 korg es-1 syntechno teebee antares kantos VST around 1'09" you dont hear any of the used effects, just the tb-303... from around 2'35" you hear the 303 signal processed by the korg ea-1 I like to keep it minimal, but I'll keep your comments in mind on my next production
