* Fix bug introduced by #5657 There was a bug introduced by #5657 where reloading a project and playing it could cause a Segmentation Fault crash. After some debugging, @DomClark tracked the issue to be likely a use-after-free being caused by m_oldAutomatedValues not being cleared when the project was loaded again. This commit adds a line to clear the m_oldAutomatedValues map on Song::clearProject(), which is called from Song::loadProject(). Now, instead of using a Signal/Slot connection to move the control of the models back to the controllers, every time the song is processing the automations, the control of the models that were processed in the last cycle are moved back to the controller. The same is done under Song::stop(), so the last cycle models control is moved back to the controller. That removes the need to have a pointer to the controlled model in the controller object. Adds mixer model change request to avoid race condition. Co-authored-by: Dominic Clark <mrdomclark@gmail.com>
