Let's just make sure we talk about the same thing here, then.
I press FUNC + trig key to create a bunch of trigless trigs. They light up yellow on the sequencer buttons.
I press four of them at once - four fingers pressed simultaneously, one on each button. I turn the encoder that controls the Conditional trigs, and all four of them go from no conditions to 1:4 (for example).
I can also do this for regular trigs - the red ones - and it works there, too.
However, I've used multiple edits like this for just a few parameters, though frequently. But from what I can think of, I've used this for delay, conditional triggers, bit rate reduction and possibly overdrive.
