If you’re going to spend up to £150, I suggest you spend the extra fifty notes and get Logic.
It’s a much better tool than GB, and the drummer possibilities are legion, including as they do Ultrabeat, drum Designer, Drummer, EXS 24. HUGE value for money, and very tweakable.
Logic Drummer has just been the subject of an upgrade, and now includes percussionists.
Just my two copper discs.
