dell laptop, fl studio 8 producer edition, axiom 61 through usb, and some pretty good 2.1 speakers (not that great for referencing though), i know its not any of those things (except fruity loops) because every computer that i used fl on does that, its usually fine when im putting chopped up samples on, usually only does it when im using soundfonts, plug-ins (especially the compressor), i know its not my processor speed because its a core 2 duo, and im on 2gb of ram, and if i save the project as an mp3 or wav, its a lot more clear and doesn't have that hissing bullshit, so im guessing it has to be fl studio...
