Hello there,
maybe those who work on Linux with Renoise know the very annoying focus problem that you can’t play with the keyboard anymore when a plugin is focused. There are a few workarounds like permafocus (I made a script for linux renoise users that lets you play notes with PC keyboard while focused on a plugin window - #12 by grymmjack) but still for me that never was a real solution.
That’s why I started to code a small tool which is running in the background and which intercepts all raw key presses/releases with the X11/XInput API and redirects them to the main window. I only tested this on my system yet, seems to work pretty fine though! I still have to find a way to do that only for windows which also contain a plugin.
So if anybody is interested and wants to help testing, message me!
