I had to migrate a number of my Axe-Fx II presets to the AX8. For anyone interested, here’s my approach. Edit: Chris from AxeFxTutorials created a handy tutorial: http://axefxtutorials.com/2016/02/i...les-to-share-among-devices-axe-fx-ii-ax8-fx8/ Preparations: If possible, use a large screen. This allows you to keep the Axe-Edit and AX8-Edit windows visible at all times, without having to move them around, and keep a Finder/Explorer window in sight as well. Connect the Axe-Fx II and AX8 to the computer using 2 USB connections, and launch the editors. If you use 3rd-party IRs, load them into your AX8 first. In Axe-Edit: Load the source preset. Execute “Save As Blocks In Library”. Copy the preset title. Remember the preset tempo. In Finder/Explorer navigate to the folder under Documents/Fractal Audio where the block files are created. In AX8-Edit: Go to a blank preset slot. Paste the preset title. Enter the preset tempo. If you want to migrate NOISE GATE settings: click on Input+Gate, then use Finder/Explorer to drag the saved INPUT block onto the Block Library widget. Beware: the migrated LEVEL parameter will always be set at -20, so adjust this to your liking (probably 0 db). If you want to migrate internal controller settings: click on Controllers, then use Finder/Explorer to drag the saved Controllers block onto the Block Library widget. Check the settings afterwards, especially the Scene Controllers. Now replicate the entire preset grid in AX8-Edit, by dragging and dropping blocks, one by one. Migrated blocks will have the same engaged/bypassed state as in the source Axe-Fx II preset, per scene, with some exceptions. If you use Reverb, add that block in an early stage, to prevent CPU load issues. If the Reverb's CPU requirements are too high, switch to Normal Quality. And if that doesn't solve it, switch to Spring Reverb. If you use 3rd-party IRs, verify that the CAB block points to the correct slot. Other parameters: there are a couple of Axe-Fx II AMP and CAB parameters missing in the AX8 firmware, don't worry about it. FILTER and PEQ on the AX8 do not have the LowShelving2 and HighShelving2 EQ types. Migration caveats: Some effect blocks are not supported by the AX8, such as the Multiband Compressor. Some effect blocks such as Pitch are limited to one instance (instead of two on the Axe-Fx). Some effect blocks on the AX8 do not support X/Y (i.e. GEQ and PEQ). Vice versa, some effect blocks on the AX8 do support X/Y, while the Axe-Fx II version doesn’t (i.e. FILTER). In this case the block will always be engaged when migrated. AMP block: its LEVEL value will not migrate correctly. Look up the value in the source preset. Don't forget to do this for the block's Y state as well if you use that (I have a global AMP X/Y switch). FXL block: if you’re using FXL to feed a power amp amp through OUT 2, make sure FXL is branched off to a parallel row, and don’t connect it to the grid’s Output (or set its Level at -80). I don’t use the saved Output block. Scenes: Don’t forget to go through scenes 2 and up. I’m using a maximum of 4 scenes per preset. Switches 1-4 are global scene switches on my AX8. I make sure that scenes which aren’t used are muted, by setting the Bypass Mode of the CAB block to MUTE (the CAB block is always the last one on the grid). Don't forget to check both X and Y values where applicable. Assign the footswitches, if you don’t use “global” switches. Save the preset. Test the preset on the hardware.
