The collection, arrangement and modification of samples are very important parts in electronic music creation, and artists usually spend a lot of time preparing sound materials. In fact, it is rare to directly use other fragments of finished works in your own works. The finished music is generally relatively complete, and the proportion of sound zone, orchestration and frequency band is relatively balanced. If you get your own work and superimpose it with the existing voice, it will definitely be unbalanced, and it will sound very chaotic. The common practice is to intercept the fragments, filter some frequency bands, and then make some modifications (those parts of the drum bass texture are very full, which are very unsuitable for sampling), or they have a good relationship with the original author and can directly ask for the timbre to be divided into tracks, or simply need which part to re-do. Well-known electronic music artists are less likely to directly quote other people's works, and they will find their own DeepForest or even make their own timbre as Kraftwerk. At present, the update of software leads to-most electronic creators will create their own timbre, including tone modulation after sampling, but there are many unknown, bad and outstanding primates. ?
