i want to set up a pad in drum rack to play different instruments in order like "apoth - bells" (among many drums racks within drums racks with the midi random) in the holiday sound pack... I've been trying to replicate it with no success. i can't get the midi effects "random" to play one instrument at a time, always ends up playing everything in the rack at once...? also when i drag a drum rack into a pad, it ends up placing all the tracks in each pad instead of keeping it all on one pad...? help!
