Brickboo, I think the point of the thread was the ability to adjust the drums WITHIN a kit, not simply raise or lower the entire drum Part. Just about EVERY modern arranger allows you to adjust the Parts easily enough. But when a snare is buried, or a clave part is driving you crazy, raising the entire kit isn't the solution.
BTW, the Roland's also had an easy to get to page where either the drums or the percussion could be muted in realtime (great for breakdowns), and there's a nice easy mute button on each drum edit page, too, if you need to silence a sound altogether...
None of this stuff is proprietary... It's time that some other manufacturers swallowed their pride and simply COPIED the best features that Roland have dropped.
Come on, Korg, come on Ketron.... where's my Chord Sequencer?
