Yes thats Right you can do it with 2 diferend styles but the problem with Sd1 is that you never know if is going to ghange to next style in a beat or in 2 measures
many times when i have to go from registration to registration I have to wait 5.. and more measures (sounds change in 1 but drums continus to play till the next style is loaded..) there is no Flash change from one to another in a meter. the same in a style you cannot go from A to B and then back to a in a mesure (just have a variation for 1-2 beats). if you do this to SD1 It will play only A
