Re: Anyone know how to make this sound Avicii makes?
It's some sort of pluck (sounds like a triangle with some pre-filter overdrive maybe?). To be safe, I'd say just start with a saw wave. You'll use a low pass filter. The filter needs an envelope with very fast attack, shortish decay, 0 sustain and just a touch of release. Your amp envelope will be similar, but I'd use a slightly longer decay and some sustain. Then you just set the synth's filter to taste and do a ping-pong delay with some filters inside the feedback loop and a little resonance.
