The problem for me is I see images of set-up and they don’t match what I am looking at on my system.
Here is my setup. Windows 10 - Elements 10.5
I have the Focusrite Scarlet Solo audio device plugged into Presonus desktop speakers.
In answer to your question…yes, I plug my guitar into the device. Yes, I have “instrument” button pushed in (the red INST is lit) and when I play, I get green signal around the gain button. I play my guitar plugged into an amp everyday and it works fine. Since the audio device reacts when I play, I’m thinking it works. No data is entering Cubase, or rather is not recording. The gauge meter does record activity when I play the guitar. So whatever the problem is, Cubase is not recording data from my device. As I said, the midi keyboard and mic work and record data.
I just had an error msg “VST System Link has been deactivated - too many receive errors.” This was the first time I’ve seen this msg.
In VST Audio System page, my Focusrite ASIO is selected. The processing precision is 32 bit float, the default setting.
Ont the VST Audio System > Focusrite USB ASIO > I have two sets of Input and Output (I added one in my attempt to figure out how to set it up.)
It’s really difficult to know what to do without the knowledge of understanding how the system works.
I also have Mixcraft 9 Pro and I have no problem recording audio tracks with my guitar.
