SCRIBER

Hi All i'm after is some tips on how to Untrigger samples. Currently I have two samples, one is a Synth Drone and the other is One Note. I would be triggering the Synth Drone underneath and occasionally triggering the One Note. I'm basically wondering whether there's a way of untriggering the Synth Drone? Before I've just had a blank zone with silence set to Mono to Untrigger things. Now I need two samples played over each other, thus I cannot use Mono made and have the blank space to Untrigger. Any bright ideas? I have found a forum that covers this but Apple Communities is down at the moment! Any help is golden! Josh
