cool
intro is far too quiet and so is the kick. for the kick i'd layer it with a short, BP filtered whitenoise click and instead of using the pitch envelope for the sweep i'd use slides in the piano roll cause the pitch env is limited to only 2 octaves and that's really not enough if you want it to be punchy enough to cut through the rest of the instruments.
the reason i don't use 3xOsc much is that it tends to have a pretty brittle sound in the high-end and the waveforms are full of artifacts in the higher notes but it's easily the most versatile synth that comes with FL. this is a good demonstration of that versatility.
