@chann3l regarding your first electronic song posted here... to be honest, the first thing that came to mind was THIS IS REALLY GREAT! You seem to really have a talent, and with just a little refinement, there's no stopping your success! It also seemed like you have a lot of experience with creating sounds too.
Next, from a technical perspective:
The first thing in this regard that hit me was that the resolution your track sounds somewhat lossy... think 64 or 96kbps encoded MP3, where the dynamic range / fine details become missing. Either you converted your master to a lossy format or Youtube had encoded your track down too far. Otherwise it seems your track is missing a lot of high frequency sparkle above approx. 8khz.
I liked the rhythm, being at least somewhat more complex than the average EDM song. But regarding the mastering of your drums: I would recommend you rethink the reverb: Think length instead of volume. I recommend going with about 260 milliseconds and 20-40% on the wet level to provide a more organic-ish reverb sound on your drums. Especially on your hi-hats (which we could have used more of): these really seem to sing with even more time and wet mix than other drums.
Also on the drums, I think you can also try to add a bit more compression: instant attack, 100~300 milliseconds release, medium threshold / ratio for a bit more 'punch' to the drums.
RE the levels, I thought the synth piece was a little too forward / loud in comparison with the drums.
Finally, regarding the ultra-minimal synth towards the end: I thought that might have been interesting to hear the use of some tremolo. Something you can try that I came up with to give a little more complexity to simple elements is chaining up multiple instances of tremelo plug-ins, each with their own partial dry/wet amounts, and even each with their own speeds. Using a hybrid sine/square wave oscillator can give a superior result.
Still a very worthy track overall!
Thanks that means a lot! Lots of new stuff for me to try and refine it some more too. I'm not sure why, but ya, the Youtube version sounds really muddy. It is to do with Youtube though because the original wav file sounds much clearer and I encoded at the highest quality in FL Studio. I'll definitely try and rework the drums a bit too and clean them up. I can also adjust the volume on the synth so that it doesn't drown the drums out as much lol. Thanks again for your pointers and support, I'll be sure to post more as I work on things. Great community this is :D
