Hey @jack.eden, there is already an effort / wish for something similar that could be helpful:
Would this be something that would suffice for your needs? If so, please vote on it or let me know if you would like to proceed with your request.
Based on previous statements by Poylend, we are already scrapping at the limits of the trackers processing powers… so i have my doubts that we are going to see realtime pitchshifting / stretching on the tracker,. But if you want to see if the community would support such a wish, we can of course proceed
