Now it works again. Don´t know why or how Wonderful world of computers.
When loading waves tune (insert on vocal track) it says can´t establish rewire , check connections.
Doing so , cubase rewire settings -input box is empty.
waves tune reads the vocal file ,but changes can´t be heard and no sound when clicking on different notes.
The odd thing is that it worked a couple of weeks ago
So where should I troubleshoot , in Cubase or in waves plugin.
I did a repair on the plugin via waves central, it didn´t help.
Waves support is no help , Cubase isn´t even mentioned in their troubleshooting area.
