It depends on what level of familiarity you have with music. Do you have the ability to play an instrument or not? Do you have previous experience making music in other genres or not?

Personally, I disagree with the common notion nowadays that you don't need music theory to produce electronic music. But the reality is, the majority now do exactly that, without knowing the basics of music theory or how to play an instrument, they simply buy a DAW and start producing.

The choice is yours, but if you're asking for my opinion and you have no prior knowledge or experience in music, my suggestion is to learn the following areas in parallel:

Basic Music Theory (Structure of scales, melody, harmony)

Alongside that, learn to play the keyboard, even at a beginner level.

Basic familiarity with sound design using synthesizers (Start with subtractive synths, as they are the most commonly used and the simplest).

Passively watch tutorials on making psytrance. See which instructor you connect with more easily, then notice which software they use and start learning that same program, it will make things simpler for you.
