It takes some time to realize which track you would like to arm which is a problem in live scenario.
What should this feature achieve?
Making selection of armed track faster and easier.
Are there any workarounds?
Yes, remember naming / track location from “previous” page where you can mute tracks.
Or just by looking above into pattern editor and count which track you would like to (dis)arm.
Ah, i wrote this via mobile phone and the link didn’t work for me (I couldn’t copy it when starting the post). So I just searched if somebody asked this already. I will update the post according to “wish layout” tommorow if it helps.
