The NES’s noise channel doesn’t actually generate random noise. It plays back a 32767 bit long sequence at 16 different speeds. Which means we can recreate it semi-accurately in a sampler!
This Kontakt multi patch has two instruments – one on MIDI channel 1 for the long noise setting (which loops the entire sequence) and one on channel 2 for the short noise setting (which loops 93-bit sections of the sequence).
I also made this Reaktor ensemble, which provides more variety in the short noise setting but lacks Kontakt’s excellent anti-aliasing tech. I’m going to try to get into Max next to see if I can create a best-of-both-worlds version.
Both ZIPs have a MIDI file showing which notes correspond to the original 16 speeds, though you’re free to play notes the NES couldn’t.
Special thanks to FamiTracker, which I used to render out a hi-res version of the sequence!
