I have successfully uploaded my IR to Cloud Cortex and have downloaded it to the QC. It shows up in the Directory view.
However, I cannot seem to figure out how to add it to my patch. The Quick Start Guide says to add a Cabism block, but that does not appear to be a device type choice. I thought it might appear in the Cab block, but that does not appear to be the case.

IRs are listed under the microphones.

Thank you, Alec! So is the cab you select irrelevant if you select two custom IRs?

Yup. The selected cab sim doesn’t matter.
