I wanted to create an simple ambient drone without knowing from where to begin. So I simply started with some oscillators, lfos and a filter. Then I add a reverb, a delay. Then I found the Benjolin "duo" (osc + gates), put some adsr, had the idea to side 3 vca (why?), played a little with the enveloppes, tried to change lfo frequencies a little bit. Then here it is. Everythinh but ambient drone :-)
I'll do my best later...
