Cab-Lab 4 is fully compatible with every Fractal Audio Cab Pack, as well as any third-party IRs in Fractal Audio or standard .wav formats.

However, only DynaCab Packs will ever appear in the program’s Cab Pack Manager. To load an IR from a non-DynaCab or “Legacy” pack, set the desired Cab-Lab 4 channel to Single IR Mode, then drag your file into the IR field or click Browse to locate it manually.
