You might need to be a bit specific when you say 'groove', Ian. I got a feeling you are referring to how much 'swing %' there is in the style, whereas I think Al is more just referring to the drummer's 'pocket'.

Mind you, up until now, I hadn't even heard there was a feature on Tyros4 about changing a pattern's swing value? How well does that work, and how well does it deal with notes INSIDE the swing value?

I always missed that old 'Swing %' knob they used to have on much older arrangers and drum machines. Mind you, back then, the patterns were SO much simpler, and changing the timebase of the clock was all that was needed!

Got any examples of something going from a straight 8 style to a swung 8 style (even if it is just moving it a BIT) to compare?
