I never had this before.
Today my Virus TI Desktop (latest drivers, latest OS...) just puts the patches on every MIDI channel to init while I was working in a project in Cubase. The project uses about 10 Virus sounds.
VC still displays the right sound names, but the Virus itself has just 'init' in its display and plays init patches.
I thought: Is there a function in VC to send all data to the Virus again without closing and re-opening the project?
