but the piano is generic trance and u should of got a better piano synth. its not bad and when it goes completely techno with the synth it sounds cool.
you really should have them seperate
the song is good, but it sounds a bit like you stuck 2 seperate songs together, either have a better transition from piano to techno, or make them separate songs altogether
that and it gets a bit monotonous after a while, but good overall
Please contact me if you would like to use this in a project. We can discuss the details.
