Hi Bill,
I rarely use a canned intro, unless I am doing a song that relates to it in someway.
Same goes for the endings.
Most times I re-assemble the intros so that I can play chords over them...this involves taking specific parts from the main variations, or even from other styles.
That way, I can play my own intro.
Roland has a similar idea already set up on the second intro, I believe...not sure about Korg.
