I’ll try to cut to the chase but it won’t be easy:
I’m using cubase artist 10.5 and a motif xf which is my midi controller and also a sound source. Cubase treats it as a vsti. There is also an application called “Motif XF editor VST” which integrates tightly with cubase, being Yamaha and all. It’s connected by USB MiDi. Normally, when I open a project that already has the motif on a track, it takes a few minutes to load up. (they call it auto sync) Then I have access to up to 16 separate tracks from the motif.
Now the problem:
I start on the motif track and I can hear it. But if I select a different track, say audio, and then move back to the motif track, the sound drops out. The only way to get it back is to reload the whole autosync thing again.
At the same time, I was having a problem getting sound from Halion Se 3, until I happened to click on the midi reset button. That worked! But then, if I select another track and then go back to the halion track, the sound is gone again, until I click on the midi reset button again. Very much like the motif.
If that wasn’t weird enough, I also happen to have a track of loop mash. I just accidentally discovered that when I have lost the motif audio connection, if I select the loop mash track it reestablishes the audio for the motif!
I am utterly flummoxed.
