Splice is actually a very dope platform. You just have to know how to navigate & search the right way, to find very good samples.
I started using Splice as one of my main sample& inspiration sources a couple months ago. But because the platform is almost "overfilled" with so many sounds, it was getting more and more difficult to find good samples, because after a time I only stumbled across the same old sample packs.
So I actually had to learn how to narrow the search down & what to type in the search bar. But try the platform yourself and let me know how it went.
