I'm curious how he messes up the time like that ("of course no drummer would be this off"). I'd like to find something that did that so I could practice for some of the bass players I get to play with. ;-)
Many recording devices/metronomes allow slight changes in play back speed...I think he was just moving the speed up and down...I gues you could automate it with a sequencer that allows tempo variation?- or most digital recording software packages
im very interested in the last exercise he did...quit counting and see if you can feel the pulse on a long interval.
Another obvious exercises is to play the metronome quiet and try to play right on it so you cant hear it...
Please list any other good timing exercises you use or have found!
