If there will be any future updates, I have a feature request:
I'd like to see a finetune option of -99 till +99 cents of a semitone (or even -50 till +50 would do). I sometimes export sounds generated from a VSTi and due to detuning one or more oscillators, they can be slightly off-tune. Now I simply open the sample in an audio editor, fix it and import the fixed sample.
Not sure if the same algorithm that's used for the note changes can handle this though. If it's too complex, I can easily keep doing what I do :)
