Sometimes i just hope, that Elektron will just release ANY new Firmware at all ! This tension whenever i visit Elektronauts and there is some news about Firmware but then theres the aaaww moment realising that other devices got the love 
But for example the Trig + YES on the other devices seams very powerfull and i realy hope that they at least do a last FW Upgrade which includes this. I guess that must be doable and would increase its value for Production a lot.
And adding python’s comment in a different thread:
Seems all possible i guess and hope they’d update this.
