Reaper: Recording MIDI even while track isn’t armed – Hosts & Applications (Sequencers, DAWs, Audio Editors, etc.) Forum

I’ve just noticed this is happening, and I don’t know why. I haven’t made any changes to preferences, options, or settings. But when I have a track selected, even if it isn’t armed, it will record midi data if I touch the midi controller/play notes. How do I stop this? It’s never done this before. I’m trying to edit a drum part, and it makes it very difficult to try out parts because it just records everything I’m playing even when I don’t want it to. Thanks
