I don't know how else you'd "synchronise differently"?
You've changed the tone. It's a new thing. A different thing playing.
Yet at no point were the instruments out of sync.
I'm not arguing psychedelics don't desync the brain (I feel the do sort of retune the instrument as it were, only for it to be better able to sync with others), I'm arguing you can stay in sync while changing what is that is in sync.
Yeah, no, that makes no sense, furthering my point that you can't. The instruments are what is in sync. Not the music. Tone doesn't matter. If the instruments remain in the same synchronization, then they are just still synchronized
the operation or activity of two or more things at the same time or rate.
The instruments are "in sync" because of what is being played on them, not from the mere fact of being musical instruments. To get two instruments being played in sync, you'd need two (or one very skilled) musicist to play them. I couldn't play in sync with anyone, I wouldn't know how.
You can say you don't agree with the facts, but the facts are still the facts.
The instruments can't be "in sync" just by the virtue of being instruments. A violin sitting on a shelf won't ever be in sync with anything. It needs to be played for it to be in sync. When it's played, what constitutes "being in sync"? The same time or tempo, if you will.
