Can anyone give suggestions on favourite sample cd for beats? Deep DnB kind of booom, or distorted-reality-like industrial sounds is what i am looking for. I have a Jomox so i am not short of a decent analog TR909 kind of beat, i am just trying to find the more extreme stuff to put on my E4

Just wondering if there is something like a holy grail of beats for the E4 in the way that there is a holy grail of strings (Miroslav) or voices (Spectrasonics SoV).
