Rob,
Great post. You have really got me thinking about using MIDI and performance mode to make things easier. Which got me thinking onto not just live but recording applications.
You see I record songs and sketch them out on guitar. Sometimes I don't go back to a song for weeks. Then when I want to re-record parts, or add extra bits I find it a struggle to re-create the same sounds.
Therefore I am thinking. Having a different performance for each song and naming it with the song name allows me to sculpt up to five sounds for each song and save them there and then. When I return to the recording I can instantly recall the sound of the solo etc not just with the internal kemper fx but also with my MIDI delay/modulation unit controlled by program changes.
Not sure why I did not think of this before. But it seems obvious now!
