@Traveler can you do a test. Download process explorer from here: https://learn.microsoft.com/en-us/sysinternals/downloads/process-explorer Then launch Cakewalk with MMCSS off.  Find cakewalk.exe in process explorer and right click and choose properties  From the window that opens switch to the threads tab.  Try and find the Apollo ASIO driver thread in the list of threads. The thread will have the driver name in it hopefully. Send a sreenshot showing the ASIO thread details.
