Just curious is there’s a way to explain this behavior or if it’s a limitation.
In the Instrument Properties Panel the Tuning knob works fine until you load your own Audio File. When listening in this case it seems the audio file shortens and lengthens as you adjust pitch, but there’s also doubling with the original speed and pitch sample, and the new altered speed and pitch sample. A bit of a mess.
If it’s a limitation, maybe disabling the Tuning Knob when a sample is loaded would be good. Out of site, out of mind. Otherwise, maybe get this on the list.
