Cubase 11 (Windows 10) alongside ipMIDI (communication driver for SSL Nucleus, among other products) causes MIDI port errors on playback/any other MCU activity.
Been down the rabbit hole with SSL tech support already, and have determined that something had changed in the MIDI port handling because Cubase v10.5 DOES NOT have the issue. Also to note, my other DAWs on this same system (S1, REAPER, Live) all work with the ipMIDI ports for Nucleus perfectly.
Cubase 11 has been set up properly with two MCUs (1 and 2 since Nucleus two banks of 8 faders) with bank one going to “Ethernet MIDI port 2” and the second going to “Ethernet Port 1” (that’s the way the order has to be). Mackie Control set to “Cubase” or “Compatibility” has no effect - tried both. Cubase ket commands set to defaults and all of the ipMIDI ports (1-6) have loopback disabled - all according to the Nucleus setup guide to work properly with Cubase.
All ready to go…I press play and ipMIDI ports 2, then 1, then both error out as a Windows popup. In the ipMIDI CP, both port 1 and 2 gets muted (not good) and no more communication with the Nucleus takes place. I unmute them, try again, same errors.
Steps to reproduce the issue:
- Have Nucleus properly installed and operating in Windows 10
- Setup Nucleus in Cubase 11 via installation and user guide
- Open a new or existing project
- Press play or any transport button. and/or move a fader
- Monitor lower right Windows event popup area for ipMIDI port errors
Through thorough testing, I stumbled upon a way to get it working, but it’s only temporary for that open session/song. Once I save/close the project and even open the same one again, the errors return on play:
The way to clear the errors (after unmuting the ipMIDI ports in its CP) is to go to Cubase’s MIDI Port setup and check (or uncheck) the option at the bottom called “Use Device DirectMusic”, hit OK, then play - perfect and smooth sailing from then on - until close. It doesn’t matter if DirectMusic is on or off when entering the dialog, as long as I switch it to the ‘other’ way, I get smooth MCU use with the Nucleus from then on.
Anyone else having this issue on Windows with ipMIDI and Cubase 11?
Again, v10.5 does not trigger the errors, and my other DAWs work as expected with the ipMIDI setup.
Thanks for reading!
