The Quad Cortext by Neural DSP is an incredible floor modelling device with more inputs and outputs than a swiss army knife. One of the reasons you bought the Quad Cortext might have been the potential and small form factor, as well as the promised ability to run the Neural DSP Archetype VST plugins natively.
Sadly, the Quad Cortex does not allow you to run your plugins on the device itself (yet), but Neural DSP is working on the functionality, and it will eventually come. Until it does, how can you use the plugins with your QC?
The Neural DSP Quad Cortex offers some pretty impressive input and output options. With it, you can record the DI signal (the guitar input without any processing) and the processed amp tracks inside a DAW like Reaper.
It is worth noting that I am on Windows, so for Mac, this might be a little different. For Windows, you also need the official Quad Cortex Asio drivers from here. For macOS, no driver is required.
I made the switch to amp modelling years ago. For such a long time, I had been an avid user of physical amp modellers. A few years ago, software amp modelling also started to catch up.
It’s a head trip to think that there are up and coming guitarists out there who have probably never owned a physical amplifier and been purely modelling—never knowing the pain of connecting your pedals, identifying a bad cable in your signal chain and working out how to not only power everything but neatly run the cables.
