Billy Foppiano:

If you go to the "Pedal"  menu (down, 2nd from left), and then go to Preset Range..set it for 100…and the Modfactor will NOW have memory locations to 100 (A +B).

Yeah, that sounds like a bug. If you're looking at the pedal settings for an H9, Space, or if no device is connected and you're looking at the settings for a Demo Device, then you should see that Preset Range page with presets ranging from 1 – 99 for H9 and 1 – 100 for Space.  But if you're looking at a ModFactor, there page should instead be called Bank Range and should have a max value of 50. We'll have to check that out…
