Hi there. Thanks for your feedback. I appreciate your honest opinion. I was not sure what genre to call it. It is not strictly techno or trance or anything else. Tech trance seemed to be the closest fit and I did listen to some examples and it sounded similar. If I just call it Electro or EDM, then people have even less of an idea of what it might sound like. I also like to try and make my songs a bit unique and not use the standard sounds.
I actually like the introduction, I did not use any samples or midi, I never do. I also used a fair bit of automation and attention to the rhythms and melodies to try and make it feel organic and building up to the drop in a meaningful way. Not sure why it did not work for you but I will think about how it could be improved.
I am not sure what you mean about the keys. Not every note must be in a strict key or scale all the time, it just needs to sound good. It does to me. Maybe it is just a matter of taste but I will certainly pay attention to this too.
I certainly don't take it personally. I want as much feedback as possible. Thank you for taking the time to reply.
