Re-listened to the audio for the changed style you did, and what I wanted to point out was about every 8th being swung nicely (in fact, that style would benefit from being swung just a little less, but I know you were making an easily heard example) but I had issues with the 16ths they were playing. A real player would have straightened those out a bit, even when the 8ths were swung as hard.

Doing this to a lot of the older, simpler styles is VERY effective, but I still have problems when more modern styles leverage the 'ghosting' and inside the beat stuff that makes the straight version of the style so tasty! Things used to be so much simpler, and back then, many things DID have a 'swing %' knob, but as patterns got more complicated, that no longer worked as well, and eventually got dropped.

But that's a great tool, Ian. Sure wish I had 'one button' swing on my Roland!
