Alot of helpful tips here
I'ma add some mo.
First off, respect your hearing. Write music on a low volume and take breaks. Unprocessed sound causes ear fatigue faster and can damage your hearing. Get familiar with levels.
Second, you are manipulating frequencies in order to make music. Don't just sit down to make a beat. Sit down and fukk with sounds. Load a sample, watch it through the Parametric EQ 2. fukk with Envelopes in the sampler channel. Attack, Sustain, Decay, Relase. Load it into Edison Audio Editor and fukk with it some more. After two hours you might not have a dope ass beat, but you might have sounds that no one has ever heard before. Be an artist from the getgo and develope your own style and sound.
Edison is also good for chopping samples and you can use your keyboard to play it like an MPC (without velocity tho).
Try searching "flp" or "remake flp" on youtube and download FL Studio projects from others. Reverse engineer that shyt to see how it is structured. Some are even decently mixed and come with samples.
Check out some basic drumming videos. Get familiar with rudiments and time signatures.
Try the swing function in the upper right corner of the sequencer or Check out the groove templates in FL. Sequence some hihats, open the piano roll, press ALT+Q and in the quantizer window you can open a folder that has pre-programmed groove templates. Load them shyts and hear the difference in the groove and see how the velocity and small changes in positioning on the grid plays a huge part there.
If you don't know chords or how to write melodies within a certain key then you should watch a few pianoplaying tutorials and some entry level music theory.
There is also a neat trick in FL Studio where you use "Ghost Notes" to help you stay on key.
Synths are fun and try editing presets. Also learn the fundamentals of synthesis by using 3xOSC that comes with FL. You can use that to make drums, bass, keys, whatever really.
When it comes to learning how to mix and add texture to your songs you can really watch any tutorial. Doesn't matter if it's FL, Logic, Pro Tools or Reaper. The same rules apply everywhere and the bundled VST's that come with FL are more than enough to get you going. Don't focus on presets, get to know what each function does and how. fukk with knobs. This is where you achieve that commercial/radio sound before it is mastered.
Listen to songs in different environment. Play a popular song in your car, then listen to it on your laptop speakers and you might even hear it at a club or at Footlocker. Notice how/if the song changes character. Does the snare sound louder here or does the hihat drown there ? Nahmean ?
Even how differently your local strugglerapper FL studio mixtape sounds compared to Dirty Sprite 2.
Finally. Use Youtube for inspiration. Check out videos of old drum machines, samplers and various hardware. See how they did it way back when, hardware sequencers and tape machines. Get to know the roots and basic ideas. Watch FACT Magazine's "Agains the Clock" series to see the workflow and approach of others. Forget about genres or the idea of wack music when learning. Every piece of music has a reason and can be inspiring when you open your ears.
Learn how to make music. Not just standard rap beats.
Be patient, read the manual, watch tutorials,and you're gonna live for those "aha!" moments.
Have fun.
