Re: Ableton Live - Need some help
Not entirely sure exactly what you're asking, but try to picture MIDI as the notes, and the audio as the sound. For using external gear, I'm a big fan of the external instrument device. I program my notes in a clip and play through the external gear and tweak the settings to taste until I am happy. Then, when I've got a good sound, I'll record that to an audio track (relatively easy to do using the routing in Live, simply select the channel with the external instrument as the audio input in a new audio track). It sounds like you've already got that part down. I would aim to at least get the notes and most of the groove and 90% of the sound design done before you go to audio; you can always alter timings for 'groove' purposes once you're in audio.
Now, I've got a MIDI track containing all the notes controlling an external instrument, and a copy of that audio in another track. That frees me up to record another part using the same synth, but I can keep the original pattern of the notes if I want to go back and change the sound. Meanwhile, I have the audio track that I can go ahead and edit, cut up and play with in the sorts of ways you can't do with MIDI.
