All About Strategy
This isn't too bad but yeah, I can see where quality can be handled better if you got more knowledge in FL Studio. Believe it or not though FL Studio is extremely easy to learn once you know all the basics - you just need someone to point you the right direction.
Organization: this is pretty simple though I'm not the best to get advice from on this point cuz my listings are usually pretty ugly too but I keep them organized in a simple way so I don't get lost. The easiest way to do this is piece your song together per sample you want to create. For each pattern I'll do the most significant pieces on it and then title it something like "Kick Set 1" or "Lead Melody 1" this helps me identify which pattern I want to use later. I usually leave the wave tables alone unless I'm using controlled animations or want to cut up patterns that section usually looks like hell for me. You just need to find your preference for that.
Mastering Keys: Make sure that you check your audio tracks and that they don't rise over -10 this is to allow anyone who wants to mix your track to manipulate it easy without any sounds trailing. The second thing is compressions and limiting. Limiting helps your track with low-high outputs and avoids clipping while compression tweaks lows-mids so that sounds such as your kicks come out with a much better overall sound. You don't have to know too much about them just use presets and find the one that works for you! Also use soundgoodizer for things like your snares.
The biggest thing is don't get concerned about experimenting. I've flirted around with that program so much that I've got all sorts of knowledge just because I was experimenting and that's where you'll learn to create things that others don't have like I have my own bassline that I use for my electro house tracks I created.
Ableton is, hands down, the best music software on the market. I plan on buying that when I get my money saved up for all my hardware.
Hope that answers all your questions, if not, go ahead and PM and I'll get you tutorials and such to help you out. Happy producing!
