50 in mind if you want to return to normal pitch (You can modify this of course with the min / max values within the automation clip too, but that's outside the scope of this and a bit more advanced) It's important to know that 50% of the knob is no pitch change at all, since the pitch wheel is bipolar, always have 50% /. A kind of weird trick you can do with pitch automation that's a bit messy but definitely works, set the range of the pitch knob to 48, this will give you 4 octaves to work with, you can reduce it by intervals of 12 (so 12, 24, 48, etc) if you want to reduce the range, but 48 will give you the most flexibility, then right click the pitch knob and create automation clip
