JJJ,
In your example you are taking a pattern (performance) IK made, so I have no idea what their rules are for use.

The User Track creator is the one taking the leap of saying "You all can use my performance" when he uploads it.
If you are comfortable doing that with your example go ahead; I would not feel good about it myself. That would not meet the intent of a performance.

Yes it is possible to do, but morally off base in my mind.
The intent in your example is to give away something someone else created. You are no longer an artist using a tool to create something at that point; more like an artist making copies of an existing tool.

I do not work here, but the benefits are still awesome
Make your sound your own!
