Fixed in next betaThe AX8->XL+ seems to work fairly well. But...
1) There are some presets that won't go; they give an error (an example is the one I uploaded to this post)
2) The volume level on the presets is extremely low. The amp block output level is always dialed down very far. IIRC something similar happens when you export the blocks and move things over manually. I don't know if that's something that could be changed or not.
