SampleRadar offer tons of samples but the truth is that, as usually, some sample packs are better, some are worse. Also, it really depends what you’re looking for. There are drum loops, construction kits, bass loops (never use them), synth loops, one shot samples etc.
“130 free drum ‘n’ bass pad samples” pack contains … 130 one-shot soundscape, pad, atmosphere samples. Each sound lasts for about 10 secs, there are some samples with slow attack, as well as fast. I’m not into Drum and Bass producing (but I like listen to it sometimes) but I actually like this sample pack. I think that these samples are much more universal and if you’re into some soundscapes, pads, atmospheres, textures you should just download this freebie (about 400 mb size).
