You can go into "Voice Edit" of a certain Voice and adjust both "Touch Sensitivity Depth" and "Touch Sensitivity Offset" parameters as desired. (Refer to Genos Reference Manual, page 49.) You can save the edited Voice as "User Voice" file then, or you can just memorize it to a Registration.
But of course this shouldn't be necessary for all Voices. If you cannot play your Genos "normally" even with one of the mentioned "Easy" or "Soft" settings for the global Initial Touch Curve, something may really be wrong with the Genos keyboard ...
