However, Roland don't allow you to SAVE the edited kit, so you have to re-do your work for every style. Korg's system, where you can save the edited kit makes the chore of converting many styles from the same manufacturer much easier...

BTW, when you are converting Live! kits from Yamaha (or any other keyboard with velocity-switched drum sounds), it helps a LOT to try to recreate the same split points at the same velocities. Those styles are designed to take advantage of those splits, and getting the wrong crossover point can change the feel and accents quite a lot.

One of the tricks that Roland's Makeup Tool editor can do is to add or subtract velocity from a drum sound (as well as the whole kit), followed by a volume control for the drum sound, so it is fairly easy to approximate the x-over points without the drum sound getting too quiet or loud. Attention to these little details can go a LONG way to making a converted style as dynamic as the original...
