I'd be interested in some info on that myself!

Good to hear. Welcome to Cubase. Please let me know how you make out! I'm hoping my problem is the 8 Gb of ram in that slave.

I'm having the same problem with Cubase 10 pro on the main computer and Vepro audio on a slave running Waves GTR and Bias amp/FX sims. My other slave runs Vpro 7 with synchron orchestral instruments and Kontakt. That one has no problems. I'm surprised that the original post was put up a year ago and no replies or help.
I'm hoping that Hodshonf has figured out a solution!

I'm running Windows 10 Pro optimized for audio on all 3 computers and they're networked via cat 6 and a network switch.

I have a related issue. Can anyone give me advice on how to get a vst synth to work through VEPro? I'm trying to use Arturia Analog lab as a plugin VSTi  but the program can't seem to find it or the Tyrell synth that I have.
Reaktor works fine as does Melda power synth.
