I want to be able to set my pitch EG modulation amount freely, but also to fixed values (in semitones). But I don´t know how to address this problem mathematically. 500.000 is +/- 0 semitones. But 500.000+ (500.000/12) isn´t +1 Semitone. (Obviously, I knew this would happened, but better try, know what I mean) Can somebody provide me with a general formula for this? I have the problem that right now I don´t even know what to search for.
