Rhythm you can see
Sixteen pads make a bar. Lit pads play. Swing moves every second pad late. You learn timing by moving things and hearing the difference.
The ideas before the software
Everything a producer knows, you can learn by ear in a browser: what a groove is, why a bassline follows the kick, how a chord progression works, what a filter does, how sections make a song. The DAW is where you eventually put it. It is not where you learn it.
A DAW is a workshop. It has every tool, and it assumes you know what to build. Learn what to build first, with tools that only do the musical part.

Choose a key and every note stays in it. Ask for the chords 1, 6, 4, 5 and hear the progression half the pop songs you know are built on.
Filter, envelope, waveform. Turn each one and hear it. Every word explains itself when you point at it, so the jargon arrives after the ear does.
Build a kick and snare, add hats, turn on swing. The field notes walk you through it with a loop you play with, not a video.
Make a bassline that follows your kick, then a melody above it. Because notes stay in key, you can try anything and keep what you like.
Arrange your patterns into an intro, a verse and a chorus. Record it. That is a produced song, and you did every part of it.
Ask it to make the chorus bigger and it will add a layer, open a filter or double the hats, in your project, using the same operations you use. Then it tells you, in a sentence, what it did and why that is something producers do. If you would rather have done it yourself, press undo and try.
That loop, change, hear, read why, undo, try again, is how production is actually learned. It usually takes a friend who produces and a lot of their patience. Here it is built in, and the friend never gets tired.
Only if you want to record audio, use third-party plugins or mix for release. You can make and finish songs here and download them. Many people will go on to a DAW; you will arrive knowing what you are doing.
The musical part: rhythm, key, chords, basslines, sound shaping and arrangement, each learned by changing something and hearing it. A DAW teaches you a DAW.
The field notes are chapters you play with, in order: beat, key, bass, chords, sound, arrangement. Each one is a loop you take apart. There is no video to sit through.
A tutorial shows you someone else's project. Here the loop is yours, the explanation is about your change, and you can undo and try another. It is the difference between watching someone cook and cooking.
Nothing to install, nothing to buy, and everything you make stays yours.
