I recently got a Roland TD-30 and noticed the ride cymbal was in the middle between the 2 crash cymbals. I know this is all personal preference but I though the ride was generally to the right on a 3 cymbal setup. I'm relatively new to drum sets (not drums) so I don't have a preference yet. I'd prefer to start with the most common setup. I went to my first acoustic lesson and sure enough the ride was to the right. I assumed the previous owner moved the ride but the manual shows it in the middle. Any idea why this would be? Pluses/minuses?
