Here is one method to instantly load and listen to IR's: Please note that Errors can occur with the beta release and you'll just have to reboot the AXE-FX, the application, or your MIDI interface, or all of them, and try again
Make all needed connections.
Open AXE-EDIT
From AXE-EDIT, Click SETTINGS and choose PRESET MANAGER to open the preset manager
From PRESET MANAGER, click SETTINGS, if AUTO-AUDITION is not checked, click it to mark it as checked, if it's already checked, leave it be
From PRESET MANAGER, click SETTINGS, then click WORKSPACES, if AXE-EDIT is not checked, click it to mark it as checked, if it's already checked, leave it be
You should see three WORKSPACES open in the PRESET MANAGER
From the center WORKSPACE, click the CABS tab, then click SOURCE and a navigation window will open
From the navigation window, navigate to the folder RED WIRE IMPULSES
From the navigation window, highlight the folder, then click CHOOSE and everything thing within the sub-folders which is in .syx format will load into the CABS tab
From the right WORKSPACE, click LOAD, then LOAD BANK
Allow the Dump to complete
From the right WORKSPACE, right click the preset you want to use for auditioning IR's, one that uses USER CAB and click EDIT (I suggest creating a patch with a simple, minimal signal path such as just amp and cab for auditioning)
From the center WORKSPACE, click any IR you want to hear, you will see activity in the status bar, and as it hits 100%, your AXE-FX MIDI IN light will flash,
You will also notice that the right WORKSPACE now displays the USER CAB SLOTS (They should appear empty even if you have loaded IR's into slots from a previous session. They only register what you have loaded in the present session.)
The IR is loaded into USER CAB slot 1 of the AXE-FX unit and voila,
Click another IR from the list and boom, it's loaded for you to audition
When you find a cab IR you want to save, From the center WORKSPACE, click and drag that IR into a user slot (I would suggest avoiding SLOT 1)
Later, you can choose that IR by choosing the appropriate USER CAB slot. Make notes as to what is where!
