I have a weird issue with Cubase 11. When there is cycle region in the project and at least one audio event with active musical mode or pitch transpose exist, Switching the cycle mode On and Off during the playback causes disk cache spike and audio drops out. This only happens if the playback cursor is before or inside the cycle region. As soon as it passes the cycle locators, everything goes to normal. I have created a video to show the problem.
This might be a bug since I have tested with two different PC computers, both running windows 10 with SSD drives. I would appreciate it If anyone can also try it with their system and report back.
