I find recording everything from 0 state to finished song (whole production process liveact) best way to catch beautiful changes.
But if you want to click record when making a song a problem appears. Automation of added devices during recording is.. not recording.
I don't know it's a design decision or a mistake but it would be super cool to:
1) record automation of devices (effects/instruments) added during recording (after you click arrangement record)
2) turn device "on" the moment it's been added, and "off" in automation before that moment
If it's stupid, tell me why
