This bit walks through recording clip automation over a looping pattern in Ableton Live, using a Wavetable device as the example. Arm the track, then switch on both Automation Arm and Session Record so Live captures every parameter tweak you make while the loop plays, whether you're turning a knob by hand or moving a MIDI controller in real time.
One detail worth remembering: recording past the clip's length overwrites whatever automation was already there, so keep your takes within the loop boundary if you want to preserve earlier moves. Once you've got the performance you want, toggle Session Record back off to lock it in.
This is the core workflow for turning live parameter tweaks into repeatable, musical automation without touching the envelope editor.
