No and yes. VPX has no Share menu at the top like MEP, so there is no way to have the VPX mixdown the project or range, export and import the AV file into MusicMaker. I have asked Magix several times for this. Perhaps you can raise a ticket asking for this feature.
So, you have to export to SD resolution (Magix mxv is the best choice), import this into MusicMaker, do your thing, then use the Share menu at the top of MMM to send the audio back to VPX. Make sure to turn off the video sound in MMM unless you want it too. The audio file will be placed at the playback marker position.
I did a tutorial on this way back, but for MEP:

Thanks for your response. Unfortunate that they haven't implemented 2-way round tripping for this. Guess they expect you to buy Samplitude Pro.
