I think they all have that, but the Korg has a couple of options on how to use it, if I remember correctly. I never found it useful on Yamaha. Seems too awkward.
I'm thinking about how to do the tempo change section of Suspicious Minds. The style I have for it has it on var four, but doesn't slow down enough.
As far as the thread topic, I use the quick ending at least 90 percent of the time, and the others are mostly wasted. Maybe time to do a little creative thinking, inspired by the Brit from Florida.
