I posted this topic already in the Apple Discussion Forums, but thought I'd post here as well. I've played and recorded guitar on GarageBand version 1 since it came out without any latency issues whatsoever. I upgraded to GB 2 today, and now there is a distinct delay in playback, with or without effects. I've done the steps as outlined in Help for minimizing delay, so I'm at a loss. If anyone has a suggestion, I'm all ears. Other than this issue, GB 2 is a great upgrade.
