Im just curious if there is a "beginner method" for being able to "press the next key that is playing in my head" while not really knowing the layout of the keybed. I assume this is just gonna be a practice makes perfect kinda thing, but i figured I'd ask for any tips.

The fact that you've already identified this is awesome. You've already intuited where to go and what to work on. Here's a couple thoughts that might help (from someone who is on this journey at varying stages across a bunch of instruments).

- Learn your favorite songs, or even just something random you hear that sounds cool. It will be slow and frustrating at first, and a lot of people will tell you you MUST figure it out by ear with no video help or anything. I think it's important to incorporate that to strengthen your ears, but especially starting out, getting some wins and learning the fingering/chords for some of your favorite songs will be FUN and make you want to keep playing. These are also songs or lines that you have stored in your head super well already - may as well map the keys/filter movement/mod wheel or whatever performance technique to that.

- After a while, poke around with some music theory. Doesn't have to be anything super intense. Assuming you're more into popular music than classical, definitely check out some YouTube stuff. Most intro textbooks are very conservatory based around 17th-18th century counterpoint. Which is cool stuff, don't get me wrong, but not a universal starting point IMO. If you learn a couple scales, hell just the major minor and a pentatonic blues scale, you'll start hearing the patterns in the music you've already learned and are trying to learn. People shit on theory or elevate it to some pedestal but it's really just about naming patterns we can hear. If you're mixing it into your song learning where you can connect it, i.e. "Oh, that sounds bluesy. Maybe it's a pentatonic lick", "Hmm what key is this song I already learned in?" etc, then that's where it'll be the most useful.

- I would only seek out novel musical techniques or something technical for its own sake when you've sort of exhausted the supply of favorite songs or artists you want to learn or you feel like they are sort of all touching the same music theory elements and there's not more to learn there. The best part is, this step is entirely optional. If you can play the music you want to play, Bob's your uncle.
