To get started in beatmaking, it is useful to start adding sound to your sound bank directory, as I mentioned in this article.
The freebeatsandsamples.com website offers you many free packs inspired by current US rappers (Migos, Drake, XXXtentacion…).
Loops and One Shot
In these packs you will find loops (an instrument set lasting a few seconds) but also one shots (an instrument note that you can then sample).
Even if the samples are few for each pack (hence their free), they are quality packs, ideal for beginners.
