Well, i think i've tried it all.
I tried on 2 computers i got home.
A mac and a pc.
On the mac i got a Fireface 800, and a midisport 2x2 anniv. nothing.
On the pc, i took the midisport. same things.
I've contacted the g66 support (they are fantastic btw) and they asked me to check everything ...nothing on both computers.
Here are the stuff i can do , and this is weird :
On the mac , i got axe edit 0.9 something.
It's always "not connected", so i can click on "tuner" make it open on the axe fx.
If i choose source : axe fx > nothink.
If i choose "bank", i can open for example a bank, click on the presets inside, and they appear on the screen of the axe fx.
i can tweak those presets on the axe edit, it works perfectly (like normal).
I can save the preset on the axe fx, in place or in another location, that's it.
I can also send the cabs...
i can send the firmware to the axe fx, and using Snoize librarian, ican also send bank presets, cabs ...etc
BUT the only thing i cannot do is receive midi messages from the axe fx.
So, i cannot save y presets on my hard drive, i cannot "call them" to have them on screen for editing etc ...
If someone's got a solution to that, just please let me know (that why i think actually there's something wrong with the midi out of my axe fx) ..
Thanks for your time ans patience guys !
