Rename your ctrlsurface.dat file in the following folder: %AppData%\Cakewalk\sonar\

Try uninstalling and reinstalling the drivers for your audio interface. It also might be worth heading to the website of the manufacturer of your audio interface to see if there is a later version. Don't rely on Windows Updates or any automatic means for this - actually go to the website.

Yes.

As a test, I deselected “Notes” in Preferences - MIDI - Playback and Recording, and all this did was prevented the notes from appearing in the first place after the record attempt. To be clear, are the notes actually disappearing, or just disappearing from view? After your recording attempt, are there any note events in the Event list view?

This is really strange. You have done a full PC reboot haven’t you?

On the “Notes” menu item on the PRV, is “Show Notes”, selected and “Show Note on Selected Notes” deselected?

Yes. In Sonar, by right clicking on the Time+ value, you can select the units between ticks and milliseconds.

If you say “no”, does it still open? (mine just opens it, defaulting to “yes”). For this task, you are not making changes, just looking (and perhaps copying the path), so saying “no” should suffice in this instance. Now, remember, this is where Sonar expects to find the ProChannel Presets. You might need to do a system search for more PCP files and then copy/move them in this location for them to all be visible in Sonar.

If you are comfortable going into the registry, then open the following key: HKEY_CURRENT_USER\SOFTWARE\Cakewalk Music Software\Cakewalk\Sonar\UserPaths look for the following value name: ProChannelStripPresetFolder The path shown there is where Sonar expects to find your ProChannel Presets.

Rename your AUD.INI file in the following folder %AppData%\Cakewalk\sonar\

Try reinstalling your Vdist runtimes. (X64) See: https://learn.microsoft.com/en-au/cpp/windows/latest-supported-vc-redist?view=msvc-170#latest-supported-redistributable-version

Arturia Pigments and UVI Falcon have had free updates (and they add useful feature, not just fluff).

Are you using the OBS ASIO plugin with OBS?

What driver mode, sample rate, bit depth and buffer size are you using ? Preferences - Audio - Driver Settings, and Preferences - Audio - Playback and Recording.

If you illuminate the FX button in the Mix Module, does that get rid of the delay? If so, then is it is an effect causing the delay (usually a plugin that uses look-a-head)
