Old post, but comes closes to my question. If I import a sound that happens to be in F onto first pad, it defaults to C but the sound plays in F. When I change the semitones so the first pad is now at F to match the sample, the sample sounds totally different. How do you change the root note of the pad from c to the key of your sample before you load it so it gets loaded at its original key (F)?
I believe you can go to the mapping page and change the root note there. It's what you would do if you had a set of samples for an instrument at different notes, you set the root note and range up and down. If I had my iPad with me I'd take a screenshot.
