I’m practicing the Euclidean sequencer, and I’m in the manual reading this: “While in Euclidean mode, it is not possible to add note trigs manually to the sequencer. However, you can still do parameter locking on the already generated trigs.”
So, what does this mean - how can I do parameter locking on generated trigs? Any help or pointers in the right direction will be much appreciated, cheers! 
It’s in the sentence before that:
If you want to convert an Euclidean sequence into regular sequencer trigs, just press and hold [FUNC] while turning the Euclidean mode off
Oh, I thought maybe it was saying I could do parameter locking on trigs generated by the Euclidian sequencer while it’s running - not after I “print” the trig notes 
I believe you can parameter lock things like probability/conditions onto a step regardless of if the euclidean put a trigger there or not and if it does put one there, those conditions will apply. this is very simple to test… just make a simple euclidean beat with 4 pulses across 16 steps with one track and parameter lock all 4 of the blue triggers steps to have a very low probability. if it works, cool.
I’ll try this myself later tonight when I’m home from work if I remember.
The Euclidean mode always play the same Note unless you’ve parameter locked some different notes on some Trigs before using the Euclidean Mode. It’s a nice way to introduce some kind of Melody instead of a repetitive (plucks, percs, drums, …) sequence.
I just parameter locked several of the blue trigs on my syntakt to have 25pct probability and they are definitely acting like they only have 25pct probability. I think you can parameter lock them without issue. Did some sound design p locks as well and those are working too.
