In Cubase 15, my Steinberg CMC-PD behavior has been inconsistent across updates. In the initial release, the device did not respond at all. After a certain update, it started working again without any changes in my setup. However, in the most recent update, it has stopped responding once mo…

Thank you for your reply. I reposted the topic because my new thread did not appear anywhere on my side, so I became worried that the post had not been submitted correctly. Since I do not speak English well, I may not fully understand the rules and behavior of this forum yet. If I create a new to…

Reco29, thank you very much. As you instructed, I reinstalled both the firmware and the driver. However, as you can see in the screenshot, the CMC-PD is recognized in the MIDI Port Setup (it was also recognized before reinstalling the firmware and driver), but when I try to add it under Devices, i…

Well, I booted up this evening and I must have agreed to a windows update when I last powered off, because it ran (slowly) today… Anyway my 8 working devices are now down to one - the AI. Are we confident at this point that this will be resolved? If not, is it possible to roll back?

Although I’ve seen spurious reports here, I’m not tracking anything specific to the CMC, and so we’re not currently fixing anything specific to the CMC. If someone wants to walk me through what you see vs what you expect, and maybe also take some repro captures, I can see if it turns up anything us…
