Limiter input gain only changes in 0.5 increment
My brother is using Logic Pro X 10.4.6 as he is in a remote rural location and has limited bandwidth for upgrades (has to go and visit my niece in the city and user her internet). For me (v10.6.1) the input gain changes in 0.1 increments, but for him it only changes in 0.5 increments. Is this the older version, or is there some preference setting we are missing.
