Slashvanyoung - I have no doubts about the level of your knowledge - I think drew_drummer and I are just saying that before one gets themselves into something with possible monetary liability it would be best to:
1: Consider all possible problems that may come up.
2: Make things as watertight as a ducks arse - legally.
3: If your going to do it - do it right.
As a side note and referencing something you said earlier I want to pose a scenario based upon something you said and I wonder as to the answer (yes, I may just be being silly but oh well....)
OK - Say I happened to own say a Guitar Center and I setup a drum clinic with ..... oh, Lars Ulric (why I'd want this is not for debate - he's just more likely than anyone else to take legal action against what I'm going to do). So on the day of the clinic I have his drum kit all miked up and routed out to the PA system and oh, by the way I'm also capturing the performance to a multi-track DAW.
So the performance goes great - my customers are happy as pigs in shit. I have a moment of genius and decide I'm going to clean up all that audio I recorded and process it so it sounds great. Then I'm going to slice it up into individual hits and pieces - you know snare, toms, kick, oh and cymbals <wink, wink>. So I do this so it has no "melodic" content and to protect the myself I call these the Guitar Center - Danish Drumtallica collection as say a Kontakt library (see how I named it something original and different <wink, wink>. I release it and it becomes my best selling product. Mind you - I did not clear this with said Lars, his management, or anyone else for that matter.
It was recorded in my space, with my tools - so from what you have told me:
The artist can't complain about a possible infringement of intellectual property because a simple drum hit doesn't qualify as such because it neither contains a melody nor is it the result of a creative process.
I'm good as gold - Lars can kiss my ass while I reap the rewards? Somehow if I thought this was true there would be a hell of a lot more drum sample sets named after (well psuedo-named after) famous drummers out there.
Yes - I'm being a bit facetious, but that scenario or something similar seems quite possible so I posed it with a smile and the curiosity of a cat.
By the way - I still think Joey should make it iron clad before he does something like this, but if he was able to I'd buy it for a good set of cymbals.
