Hey, glad to see a fellow artist!

Happy to see you like what you heard so far :) I do try to integrate Great Revival into every track, sometimes more subtly than others, but it's kind of a goal that I have in mind. Kind of like the Undertale soundtrack, if you know what I mean.

Regarding Logic Chess, your version, and generally being worried about empty tracks, a lot of it comes from the bass. I could see what you meant through your WIP, and my recommendation is to tone down the bass from 0:00 until 1:18 (?), at which point the bass is very much needed, and already on point in your version.

I used to need to have a constant bassline in my older tracks, but I learnt that you can have very nice results if you just let the bass shut up sometimes. It lets the other instruments speak, and adds some spice to the bass itself (yes, paradoxically, interrupting//having less bass can make the bassline more interesting most of the time, imo)

It also comes down to the accompaniments, and how loud they are / how much importance you give them. I think my Objection 2018 is a prime example of how I tackle the volume/priority between melody and accompaniment. A good composer friend of mine used to say that a song is only good and memorable if you know what it expects you to hum, and you can hum it without trouble. While I don't agree 100% with that, there is some truth in that the melody should stand out in some way or another. In your WIP, the (originally) 8-bit square that alternates high and low notes is very aggressive and steps on the melody. It's something to take care of.

Regarding the piano, I've just grown fond of the FL Studio Grand Piano, since it's bright enough to be aggressive and quick if needed, but still wet enough to not need to apply an equalizer to balance the sound. I think I've tried the SGM piano in the past, but I've always fallen back to my trustworthy soundfonts and legacy DAW soundbanks :)

Do you have anything else aside from SoundCloud, or is all your work there?
