Things I've learned about Ableton Live

• Live has no facility for quickly switching between songs (aka "sets") via MIDI so you have to pile them all together into one giant set (unless you want to use the mouse and keyboard to move to your next set). This means the order you perform your songs in will be fixed on whatever order you have queued up, which blows. (Unless I can think up a clever way to jump around via MIDI.)
• After thinking about it I thought the easiest way to start using Live in a live setting would be to have a fixed sequence of scenes (verse, chorus, verse 2, chorus 2, etc) which would go off without any input from the user (me), but I could hit a pedal to stay in any given scene if I wanted to pad it out, solo more, improvise, etc. But there's no "scene follow action", so you have to rig up some crazy solution via MIDI.
• By far the majority of tutorials out there are for "live looping", Kid Beyond style or DJing. I can't find much in the way of singer/songwriter tutorials or using Live inside a conventional band.
• The most commonly used technique with a midi pedal board as far as I can see is instead of triggering specific scenes you set up pedals for "next scene" and "previous scene" so that you can advance (and backtrack if needed) through the scenes. No functionality for this exists inside of Live so you have to use Bome's Midi Translator or an equivalent to simulate keystrokes when triggered via MIDI.

I think what I want to do will be possible, just takes a lot of fussing around.
