Hello:
I too have a PR804. How do you like yours?
About your question. You will need to use the Panel Write feature.
To show you where it is, press the Program Menus button, and choose Sequencer. Here you will see the Panel Write button. Use this "AFTER" any changes.
Experiment with one or two changes, and see if this will keep the changes. Let me know the outcome. Thanks,
I have a funny feeling once you get past this point, and want to save as NX, your going to have more questions...
Anthony
