I knew exactly what you meant by “one-shot”. No problems there.
Of course I understand that people sample one-shots all the time, and I’m definitely not denying the fact that you can usually “safely” sample generic sounds and manipulate them for your own needs… everybody does this - even me! Nobody in their right mind is going to waste time and money making a claim against you for sampling a 909 kick from their song, or for sampling any other kind of very basic sound that could easily be recreated or grabbed from countless other sources… it’s just not worth the hassle. (And in many cases, the artist probably doesn’t even have rights over the sound itself in the first place, since they probably sampled it just like you did, heh)
Where you need to be careful is with “signature” type sounds, or anything that can easily be recognised by the listener. Sampling a really basic sawtooth synth sound from a generic trance/techno/dance/whatever track is probably fine, because it usually doesn’t have a lot of creative merit, and any idiot with access to one of hundreds of VSTi’s could make it. But it’s those other unique sounds created by really skilled musicians - the sounds that make us go “wow, how the hell did he/she do that?!” - those are the sounds you need to be careful with.
Technically (and definitely legally) speaking, it doesn’t make any difference whether it’s a 30-second loop or a one-shot sound that is less than 1 second, since they’re both intellectual property and therefore both protected in the same way. Hypothetically… if you were releasing your music commercially in some way, and you were one day accused of illegally sampling from another commercial song… if they can trace that sound back to its original source, then you will have a potentially rather expensive problem to deal with.
Sampling is really such a bizarre world that is rather difficult to predict. Sometimes people get into trouble over the smallest sound bytes, and then other times you have assholes like Timbaland who rip off an entire piece of music to use as the backing track to a shitty pop song, and nobody bats a damn eyelid. 
The main point I’m trying to make here is that anyone who does get into sampling should simply be aware of the legality of what they’re sampling, how it might affect the music they are creating, and ultimately how that music can be used, sold, or whatever else they want to do with it. Some stuff is public domain, some is licensed under creative commons, some artists simply don’t give a shit, and some artists will fight you to their grave if they have to. 
I understand, and I wasn’t trying to imply that you said “hey kids, if you want cool sounds, just go and rip off other people!”, haha. That’s not what I meant at all.
Are you aware that I actually own the copyright to any sound that has been processed with Glitch, and that every sound is encoded with an undetectable, unremovable digital watermark that I can use in court to prove it?

j/k… that would be pure evil
