Opening cpr to find sample rates have all changed

With two of my projects I opened them to get a message that the sample rates had changed for some unknown reason. I shut down the file and reopen hoping it rectified itself. Nope. The damage was done. Some discrepancy between 48000 and 441000 popped up from nowhere. It’s nothing I did. The projects opened fine for months beforehand. Then suddenly this. It plays through ok but now the grid has shifted to a different interval. Any idea how I might get the grid back to it’s original placing?
Kind regards Ken

Hi,

Most probably the Sample Rate of your Audio Device changed.

Is the project set to the same sample rate as before now?
Did you check the interface sample rate was matching?

What exactly happened with the message, did you allow it to resample audio…hopefully not!!

Thanks for responding. Unfortunately the damage has been done. The project sample rate suddenly changed itself to 441 for no apparent reason. The ASIO rate when I checked was 48000. The project is months old and only went haywire the other day. As the damage has been done I’m left with a project that plays fine but the grid intervals have all changed. I need to try repairing that part. That’s where I need the help.

Yes but for no apparent reason. The project is months old and was fine until the other day. Something somewhere changed it all. The asio rate is 48000 and the project rate changed to 44100. Whatever happened. So now I’m left with a project that plays fine but the grid intervals are all over the place.

If you’re 100% certain the project was at 48k then just change it back.
Then make sure the interface is the same.
Cubase wouldn’t change it for no reason…either the interface got changed or it wasn’t where you thought it was in the first place.
You also didn’t respond to the question what exactly happened when you got the error…if only the project changed you could just change it back. If you let resampling occur then things get tricky.

Also to be sure…you say the project plays fine but is it perhaps playing at a different speed and tuning because of sample rate mismatch??

To be honest I’m not sure what happened other than for no reason a relatively old .cpr suddenly did this. My guess is that it changed the sample rate maybe by something I did inadvertently. Anyways I’m now stuck with the result. It plays in the right key but the grid intervals are all over the place. This is what I’m trying to rectify. I’m afraid of making the problem worse by not knowing how to fix it.
