good start
Well to me this sounds like a few random notes played over and over while you turn a few knobs. I also recognize a few SLIGHTLY tweaked presets from the MicroKorg. If this was an ambient song I'd give it a 4, but as techno I'd give it about a two. For your next song try to develop a constant melody and add some drums, pads, bass, and all that. It seems like you did all this live, and unless you are reaally good at piano, i recommend you do some editing. There's tons of programs you could use, like FL studio, Cubase, Garage Band, etc. Its a good starting point though. I think itll be interesting to see how you progress. Keep working!
