Try this: Take a wave with lots of harmonic content, maybe an Ens machine. Make a pattern a bar or two long with just one regular trig. Set the Hold, Dec and Rel parameters to fairly high values so the note lasts most of the pattern. Give the note some “character” in terms of its filter settings and LFOs.
Now add a few trigless trigs. Plock them all to change just one parameter, then another. Let the sequencer run and listen as you change the plock values and move the Ttrigs around on the grid.
Some changes will have more effect on the sound than others of course … I find it’s good to be fairly methodical till you get a feel for the possibilities.
Occasionally convert some of the trigless trigs to ones that trig either the filter, the LFO or both. Or just the envelope and not the others, etc. Continue digging.
TBH this isn’t a quick learning process, and the advantages sound better on paper at first. I routinely spend entire sessions doing what I just described and my batting average is probably 85% useless garbled noise and 15% angel choirs.
