Thank you for the reply, I will check it out!
Yes I know that only the pitch change will sound bad, along with bops sounds every few seconds, but what I mean is something like the soundtouch plugin for foobar2000 for pc. Basically there is an option for "rate adjust": this option let you change the pitch but automatically, based on how much you changed the pitch, it change also the tempo. So if you go down on pitch the music will sound just a bit slower but it isnt very noticable and also it will sound without any distortion or bops.
But I am ok if max decide to only release pitch change, then I can change the tempo myself manually since there is already the tempo feature
