Maybe you need to be clearer with yourself from the start about what exact output it is you want.
Messing around with fun ideas is ok for a while, but becomes a frustrating distraction eventually if it’s not all part of a drive towards a defined end product.
When talking about such things as parameters and process in defining music (including the importance of limitations) my mind always wonders back to 4’33 by John Cage. The parameters are clearly defined; you need at least one musician, at least one instrument and, most importantly, an audience. The process is also very simple and very much defined by the ultimate in limitation, that not a note is played for the entire performance.
If you’ve never seen a performance of 4’33 I recommend it, as it cements in your mind the true meaning of when John Cage said,
“Everything we do is music.”
