First of all - what is the difference in auto-tune and auto-tune EVO (same with harmony engine /- evo and so on.. ) ? Is the Evo cutted version or upgrated version? Secondly i cant keep up with all these different types of autotune .. on the pictures it seems like everybody got antares with different options .. to they have updated versions or what ? mine is 5.0.9 and i dont have half the buttons i see in videos .. But the most important question from them all is why dont i have port number selection on my autotune for midi controlling . I use FL studio and antares autotune VST version 5.0.9 and im trying to control it with my computer keyboard but there isnt port number in my auto-tune . Is this to do something in my fl studio settings (cause ive tryed everything in midi options and so on ) or is it something to do with this that i dont have full version of auto-tune ? Thanks everyone for anserwing and sorry for my bad english.
