Not bad
Not bad at all, it's a pretty catchy beat. The main melody or synth I don't think is all that special, and a few of your bass lines could use a bit of work. Not all of them, because I really like one of the synths, and the bass line while that's playing flows brilliantly. Your drums I think are your strong point. Very creative, and I love them...no drum criticism from me, they're amazing. Gah there's just so many melodies and synths you probably don't even know which ones I'm talking about :/
Well, it's great that you switched it up so many times. Really makes the song interesting and avoids having it sound repetitive. Overall I think it's a great track, regardless of one riff I didn't like in particular. Keep up the good work.
