Hi,
I use the Steinberg UR242 and a Yamaha S70XS synth with I’m using Cubase 8.5.30, latest version of 8.5 on Windows 10 64 bit.
It’s related to hearing the audio from a MIDI track driving an external instrument, or rather, hearing it in full stereo (not it’s pure MIDI, not modeling . I have used this last year no problem at all (albeit on an earlier version of Cubase, 8.0 and 8.1).
To hear my MIDI tracks play, I have a monitored audio track taking the stereo input bus, configured to take 3 & 4 on the UR242 which in turn is fed from the Yamaha outputs and routing this input bus to the stereo output bus in Cubase which is configured to use outputs 1 & 2 on the UR242 which I can hear on both my speakers and headphones.
Having mainly worked purely in pure instrument tracks for the last year, I’ve opened up some old projects where I was using my Yamaha XS70 on MIDI tracks, and now I’m getting no stereo audio from any MIDI tracks at all, I only get mono on the right side. It definitely used to work perfectly. All VST tracks are perfectly fine, full stereo.
Now when I use the Yamaha in local mode, I get stereo no problem through the UR242 with Cubase shut down. It’s only when being driven from Cubase that the problem arises. This is no matter what the instrument is selected on the Yamaha there’s no panning on the mixer in any tracks in Cubase so not getting anything on the left is not due to that.
As I say if I switch to local mode, I get full stereo so the Yamaha outputs stereo audio no problem and the Yamaha receives and outputs MIDI notes in all cases.
If I create a mono input audio bus from UR242 input 4 which is taking the Yamaha right output, and use that instead of the stereo input bus, I get the mono signal in both speakers, all coming from input 3 effectively, the left one. If I create another similar mono input bus for UR242 input 3 coming from the Yamaha left output, and do the same, I get nothing at all. So it’s like in stereo mode, input 3 on the UR242 is completely left out.
Now interestingly, if I pull out the right audio cable out of the back of the Yamaha, i.e. input 4, I can hear in the left side from just the single remaining cable for the left output, i.e. input 3, but when I put back in the right cable, the left audio disappears and only the right can be heard (again this does not happen in local mode, I can hear both so there’s nothing wrong with the Yamaha outputs or the cables.
So it’s like Cubase is turning off one of its inputs, when the other input is present, when using an audio stereo input bus?
As well when you press a key on the keyboard you can see only one side of the stereo signal on the audio track is moving in the mixer, the right one, so it definitely appears that the issue on the audio input bus, and not in the routing of that audio to the stereo output bus.
I’ve created a brand new project in 8.5.30, still the same. I’ve done reboots of all the equipment, makes no difference.
Any help appreciated if anybody has encountered anything like that or could suggest something to try that I have not.
