currenly using a lot of sounds like these in my own tracks, im recording just about anything, then putting it into a sampler and experimenting. looping them up, applying lfos to the start and endpoint of the loop, filtering ect and getting some alien soundscape from me pouring out a glass of coke, or hitting a saucepan with a packet of biscuits.
I also get better basslines from samples, just with a heavy lowpass filtering.
I will be posting a track in the production files using these sounds.
