Every now and then (at least once per hour) cubasis changes all of the midi sounds, and all of the volumes for both audio and midi sounds. My projects are getting rather complex, and each time that Cubasis changes everything, I have to restart the whole process!!!
Thanks for your message.
The topic described sounds to me like a rare UNDO problem, that will be addressed with the next Cubasis update scheduled to be released very soon. Please let me know if UNDO was involved in the steps when the problem appeared at your end.
Please note that Cubasis 1.9.9 has been released and addresses the UNDO/Redo topic.
Please let me know if the fix resolves the issue stated in your post,
