@Eskur! i've written a script that lets you Export the IR from Convolver, and also Import an IR (really, selected sample), to Convolver. so this solves the whole "having to click on the Load button and navigate around" issue. it was Jonas the PlugExpert who requested it, and i got it working with some base64 encoding help by another guy. It's pretty neat! This means you can take an IR you have in Convolver, and modify it beyond recognition, and then load it back in without issues.
Also, really glad you mentioned it!
For the "Full effect command", i've set up a special "Edit Mode switcher", that detects you're in the effect column, and sets the editstep to 0, and when you disable the editmode, it jumps back to the editstep you were at before running the script.
@WobbleBlast that forum thread was magical! i have bunches of those already in Paketti (my tool for Renoise) and will keep studying it. That was a great thread!!
