can the recorder record vst outputs within Gp, I get no wav file recorded, yes I read manual
What recorder do you mean?
No, you have to loop back the vst output to an input using a third party software (Loopback for Mac or LoopBeAudio for Windows). RME audio interfaces, and perhaps audio interfaces from other brands, offer an hardware loopback option, which is even a better solution.
Currently, our audio recorder only captures audio arriving at the inputs. Capturing the output is on our list for a future version.
If you want to record the output of a specific VST in a single rackspace, try the free MRecorder plugin from Melda Productions.
