Now, sorry, what was the question?
To play a chord, you just need to hold down the notes of the chord. That's true. But there is also a question of note order.
For example, in C major, I can play 1 135, or 1 351, or 1 513, or even 1 125
Finally, my conclusion is that as long as the left hand is 1, the right hand can try more notes. So it's OK as long as the BASS is right, right?
I want to know if this understanding is correct. If I get the answer right, it will help me use some VST plug-ins.
