Loops o samples, That is the question

I have heard and read many beatmakers and producers say they got a loop, others who took a sample, but in theory is the same, the difference between these 2 are involved in as, editing:

Loop is defined as the audio is repeated again and again thus creating a “soil” almost ready for a base rap, I can take an excerpt of a song then put hype, box, low and ready (boring). Or if in the case of a drum loop, the rest is placed; Notes, low, etc. (including).

Sample means showing, a loop can also be a sample, but the difference is that the beatmaker, no audio remains intact, if not occupied by the specimen samples. I mean: If using a MIDI keyboard, For example, we cut the sample, remove, set change tone, etc.. and create a completely different tune, giving a different sound, order samples, eliminating, course changing and creating something new and original.

In practice and in the early, easier it is to occupy or take “samples” another song and leaving intact, making it in a loop. I think it all started well and would be contradictory to say that it is unethical, For just as I started “sampleando” that the truth would “loopeando” alien song.

It is illegal to take excerpts of other songs and then sell.

I hope this has gotten out of the doubts.
