im not talking about automating stuff. i mean to record audio as you do stuff and then take it on the playlist as any audio

try using a microphone.

You can have an audio channel receive audio from the Master. Just mute it so you don't get feedback (or route it to something other than the master channel, or change Monitor to OFF).

If you're doing something involving launching clips and are trying to record that channel as a clip, then make sure to remove the stop buttons of all other slots so you don't accidentally trigger a new slot, unless that's what you're after.

Variations of that should get you what you're trying to do hopefully.
