I'm able to update the firmware on my axe fx ultra and dump the presets, banks, etc. to my computer (I have no idea if they are corrupted or not though), but I cannot transfer presets or banks from my computer to the axe. I'm running mac os 10.5.7 and using SysEx Librarian and a Lexicon Omega. The "midi in" flashes for about half a second after sysex librarian says "done," but the preset does not change. I've tried raising the "pause between playing messages" and lowering the transfer speed, but neither of these have helped. Any ideas? I'm NOT using the editor. I was under the impression that when sending files from a computer to the axe without using the editor, you simply need to send the file and the axe will know what to do (i.e. you don't have to go to some special menu in the axe).
