I read an article with Jeff in Bassics where he said Americans are getting too lazy, and that he essentially despises metronomes. My instructor has me practicing with drum sequences through Acid Pro & Stylus RMX. I use a different style each time I practice (i.e. samba, swing, rock, etc...). He really doesn't want me using a metronome, but I cheat sometimes. I say use what helps you get better. That's the goal anyway, right?
