gabber/hardcore does not have to be cavemen or simplistic per se; actually, i know from attempting making something with heavy distorted beats myself how difficult it can be, because heavy stuff tends to push other stuff away and everything can get muddy and crappy very fast. so it is by no means a ‘simplistic’ genre to do. as i said above, there are plenty of hard styles which are not as basic as gabber. however, the basicness of it can also be perceived as ‘primitive’, in the good sense of the word, as in ‘raw’, ‘real’ etc. there is a certain appeal to no-nonsense hardcore music which just bangs away and doesn’t get complicated. as i said, i personally have a different preference but i am by no means a standard for anything at all.
for a kind of ‘you-scratch-my-back-and-i-scratch-yours’ approach as kazakore mentioned, maybe check out this thread: https://forum.renoise.com/t/post-your-latest-project-work-in-progress/33288. the idea is to comment on another track before you post one of your own. it is a good idea and it has gotten quite a lot of replies. not guaranteed to get any feedback but it might work for you.
that said, i understand your need for feedback and seeing how i have listened to this type of music before and can get into it, and because you took all the time and effort to explain yourself without coming across as bitchy or whiny, i’ll listen to your track and comment on it.
