I know this isn’t a Sonar support site, but if I can connect with someone who knows how to set this up, we can take it offline.

I wanted to get back into writing and recording.

First, I had some things working today, and now they just don’t work anymore.  Frustrating.

In Sonar, my MIDI devices are Yamaha MOXF6/MOXF8-2, for both input and output.  Audio device is Yamaha Steinberg USB ASIO.

On the MOX, I have USB MIDI turned on, local keyboard off.
DAW set to Sonar.

Like I said, I was playing around with some VST instruments and making sure that MIDI tracks were recording.  So I know the basic settings and connections are there.  PC audio (YouTube, etc.) plays through the MOX.

I have no clue what suddenly changed so that now I get no MIDI activity.

When I first got my MOX I was excited to use it as a control surface. 
I quickly gave up on that because I couldn’t get anything to work on that front.

I’d really like to get it going this time and set up a productive work flow so that I’m not spinning my chair around between computer and keyboard.

Appreciate any help!

Edit:  I just thought to use the virtual keyboard as input, and it works.  I can play VST instruments with that, but not the MOX.

Wow.

Have you checked your MIDI Transmit Channel on your MOXF and made sure you’re receiving on the same MIDI Channel in SONAR?

Yes.  MIDI Tx on MOX is channel 1, and whether I set the Sonar track to 1 or Omni makes no difference.
