My H9 Control app indicates that my H9 Max has version H9_5.4.1 and it indicates that is "up to date." Nevertheless, I have reinstalled this a couple of times now.
On the algorithms page in the "H9" column I have UltraTap, Resonator, EQ Compressor, CrushStation, SpaceTime and Sculpt. No PitchFuzz.
Ok, it sounds like you just need to download and install the latest version of H9 Control, b/c that needs to be updated as well. You can do that here:
By the way are you on Mac or Windows, and what version of the OS do you have installed? The app should tell you that it needs to be updated. I don't understand why it's not telling you that…
