I'm looking for plugin that would allow me to blend in background noises/loops similarly to Audiothing Speakers "background noise" section
and Speakerphone "samplebay" 
My preference is more to
1. allow the user to add his own samples
2. blend in multiple samples with different settings, ideally option to blend with envelope follower (like in audiothing speakers)
3. play regardless the transport is stopped or not
I know that something like this could be hacked with sampler. Essentially this is something like sampler/looper crossover but more tailored towards audio effect that blends in multiple layers of noise/room tone and whatnot to existing track.
