The Sub Phatty manual is actually very good and this is just a tiny nitpicking thing, but the patch initialization section tells me to do the following:
In the MODULATION section, turn the LFO RATE to 8 (…)
This is actually quite hard, since the only marked ticks are for 0.1, 0.4, 1.5, 6, 25 and 100. 
good question. i wonder if they meant 8 of 10 (just weren’t thinking of how it is labeled when they wrote it). or if they really mean 8 as it labeled. I can’t quite think of where you are looking in the manual right now. what effect are they trying to achieve?
See Patch Initialization on page 14 of the manual.
