I tried to Google it, I tried to quickly go through forums, but I didn’t find what I was looking for, it’s also hard for me to give it proper name, but I came across something what I can’t figure out.
In added picture this is what I need to replicate in the new score (and I need that also to be in the parts). Any tips on how to do it? Adding more notes then it would normally fit to the measure, but only in one instrument. That’s very important.
Thank you very much!
