Pxx - fine pitch offset setting. xx = offset, 80 is default. New frequency register will be subtracted by (xx - 80).
Even though different chips may have different pitch tables, which are reflected in the instrument macros, values greater than P80 will always raise the pitch, and lower than P80 will always lower it, though not necessarily by the same amount across different expansions.
