Exactly ! Once the guy had explained it I thought it totally made sense, and the way you put it is crystal clear.
Yet this "trick" is very worth mentioning in my opinion, as any beginner (such as me) would naturally conceive a sound from the source to the end of the signal.
Before seeing this tutorial a week ago, I was putting a lot of effort in the choice of the machine, then the right oscillators, then the oscillators parameters (I'm on MM)... And in the end I was not always satisfied with the sound, so it was a bit disappointing.
Anyway, I often encountered some weird artefacts that enable me to know the instrument better, but I was not reaching the sound I had in mind, or if I did it was not as quickly as I wanted (compared to the OP-1 that I've had for 1 year now).
With such approach, it's been easier to reach some glitchy sounds I had in mind, or metallic bangs...
Above suggestion to reverse-engineer free Elektron packs is another very important advice.
But I would really go first to the documentation. Once you have the concepts in mind, it's so easier to dive in it.
