have always wondered about this!
back in the late 90's i remember my mates talking about the "4 second rule" (meaning sampling anything for under 4 seconds waives copyright)
i think it was, not even sure if it was entirely true, where does copyright hold on a chord stab
that lasts for 8 seconds?, where is the artistic integrity in sampling 1 note? or performing a filter sweep on a chord?
makes me wonder if its a good idea posting my old stuff, back then i only had samples ripped out of other mod's, couldn't even credit the recordists/artist's cant remember its been that long.
these days i just sample my Hardware synths & perform my own knobulations
