Hey Sanko
I meant arrangement dynamics. Layering, velocity, filters, little filling effects and automations kind of transition the plain idea into a full song. when talking about piano roll editing i feel like your most melodies and drums are too "safe" and need more layering and movement. You can try arping melodies as fillers too. Arp kind of fills all that blank space between your main lead and chords. Its not dominating in a song but is just there in the background and gives more movement to a song. All the chords should be layered. Drums are not that hard to make dynamic cause most people are using samples and adding all these clicks, hats etc. Automation is crucial for energy transistioning. You need more synths to make automations effective. Do not be shy adding more tracks and layering stuff. Just keep it in balance. Most of these things come with try and error method anyway and just making more songs. Making mistakes and doing better with next songs. Cheers !
