You can review this Bitwig Preset after you've downloaded it.
It's an 8 bit (26khz and -72dB gate), and then a high cut and identical 8-bit inside. The high cut only cuts the very top and the second 8-bit is the same. Not sure I see the point to the patch, and the author then also writes "E-mu 1200 imitation and "no idea if this is accurate or not", so ... ?
Interesting, a bit-8 inside a bit-8, but doesn't change the sound much.
