Sad Sounds Of A Robot

I think I took a big step forward, but I still feel like I’m coming in last on production/mastering compared to pretty much everyone else here.
Any advice on what I’m doing right and wrong would be appreciated.

Writing interesting melodies is always something I struggle with.

Thanks for the advice and the pointer towards key frequencies and that site with all of the free VST DSPs :dribble:

It’s always good to try to be better. But this track itself is amazing as is, really powerful soundscapes you have built there.

Thanks a lot :D. I have trouble hearing the song as a whole instead of individual tracks, so sometimes I’m not sure if it actually sounds the way I want it to.
