I received a response from the Support team. Unfortunately, this is how the current algorithms behave and switching between delay programs or reloading existing programs will trigger the pitch warps. The suggested workaround is to use Hotswitches to control subdivisions (and the level of different heads if available).

I did provide some feedback for the development team so hopefully these glitches will be addressed in a future firmware however I’m not holding my breath. Truth be told I’m a bit disappointed as I loved the sounds I dialled in but currently, it’s just not workable in a live environment… Moving back to the Timeline for delays.
