Hi, you need to tell me which version of FL you use, what type of effects or plugins you want in the song, but I usually master and compose in Ableton LIVE 10, then move it back to FL based file formats. I use all sorts of mastering plugins and my sweeps, lift, risers, ect. are made in Native Instruments Massive or Sylenth 1. As far as the composition, you need to let me know of what songs and artists are similar to your style and if it is amped or chill and laid back-- like if you say Kendrick Lamar-- then I have to ask "Which Kendrick tune?" (there are a lot), or if it oldskool like GangStarr or Tribe Called Quest or P.E., because the use of sirens, emulations of jazz or necessary samples, or if you wish to include your samples, you gotta credit or get write something similar. That's how the game is. Anyway, let me know and I will work with you to make your track sound professional, especially in post production E.Q. and mastering. Also if you need live guitar work or some other live instrumentation. I try and do everything WITHOUT Antares Autotune, but it can be used if you feel that you need some part "re-tuned;" in my experience it is better to re-record, change the composition around the supposed "error," or find a different workaround. So I hope to hear from you.
