Acquire and generate signals with NI USB-6003 simultaneously but at different rates?

I need to acquire data using analog input while also generating a 0-10V control signal with the analog output. The output channel's max scan rate is 5000 scans/s which is fine, but I need my input channel to scan up to 50,000 scans/s.

The NI USB 6003 can sample up to 100,000 scans/s, but when I add an analog input and output channel to the same session I get this warning:

Warning: The Rate property was reduced to 5000 due to changes in the session configuration. 

Do I need to use two different sessions, one for analog input and one for analog output? My understanding was that I would not be able to run two sessions at once then.

Yes you would need two different sessions.

@Walter Roberson As far as I know, you can not run two sessions at the same time on the same device. I have tried creating two sessions (one for AI @ 50kHz, one for AO @ 5kHz) and when I initialize the second session on the same device, it deletes the first session.

I was hoping for a workaround to "running" two sessions at the same time on one device

Again, I only have one device (NI USB-6003). The link and info you attached applies to two devices when you can use two different sessions. You can't use two sessions on one device...

The post includes a link to a Mathworks documentation example that says specifically that you cannot run two different speeds in the same session.

At the moment I do not find documentation that says that you cannot run multiple sessions on the same device. It sounds plausible, but I also seem to recall posts in which people did just that under some circumstances.
