Kenny Segal says that "sometimes the best thing to sample is the space in between the actual notes." this makes a lot of sense - generally, a sound will degrade & distort as it decays & a lot of the more interesting textures happen here, only it is too quiet to hear well. try making this louder & hearing what kinds of sounds you're able to bring up into a more audible volume. you'll need a decent tail to work from, so try adding a lot of release or reverb & delay. if the section you pull out is still short, stretch it out & let the warp modes add even more texture to the sound. once your satisfied, consolidate (cmd + j) & drag it into simpler. try playing this with the original sound as a layer to balance out the ethereal sound with a more direct version.
