Figuring out the DAW first, try and make a full song from start to finish, even just using one shot samples to make it so as not to confuse yourself with the intricacies of some VST’s,
(Example; some VST’s only work on certain piano keys in the piano roll editor, so when you have entered notes, you see the keys being pressed but are hearing no sound)
Don’t worry about mixing/mastering/panning/FX rack and volume etc,
Just try and compose an arrangement that you like the sound of for now from start to finish with all volume level set exactly half way, realistically you should be able to complete a basic track in one week.
When thats done, you can export your track and listen to it on a few set ups, stereo in your kitchen, in your car, in your bedroom and hear how different (and poor most likely) its sounds from system to system.
When you now hear something is to loud, to low, to overpowering, return to the DAW and adjust volume on the areas you noted then assign the individual tracks to channels on you FX mixer,
The rest from there on is the rabbit hole…………………
(But the above as first dive into the DAW will teach you quite a bit)
