As the previous poster explained, there are two versions of the fx. There is a dsp chip in the hardware with the fx onboard. This enables you to use the fx without latency on the inputs. If you use Cubase, you can set them up in the Hardware tab of MixConsole. If you use another DAW, you can use the external app dspMixFx to manage them.
To use the fx in a mix, you’ll need a license to activate the software versions of the identical plugins. Everything gets installed along with the driver package available on the downloads page, but you’ll need to ask for a license. There is a new version just published on April 15, 2020 if you don’t have it yet.
These units are bundled with Cubase AI, as well. You can use it to try the integration if you don’t already own a higher version of Cubase.
If you registered your unit, you can open a support ticket. They may grant you Basic FX and Cubase AI licenses. I’d remove the profanity when attempting this, however.
