Porter mentions this synth as one of his favorites. It is part of FL Studio.
3xOsc is a great VST, you can basically make any sound with this, and it sounds amazing. This is what I use to make M83-ish sound with, and I also use this to make white noise effects, etc etc
This plugin takes hardly any CPU usage. I don't understand why people use Massive and Sylenth1 for Whitenoise and Detune Saws when 3xOSC does it with about 0.2% CPU Usage.
While 3OSC may seem to be simply a 3 oscillator synth, the possibilities are nearly endless when you get under the hood. I've seen snares, trumpets, basses, and so much more made with 3OSC!
