Hi,

I have just tried to connect the Audiobox iTwo midi in/out port to the guitar amplifier midi in/out.

I can send command to the amplifier to change the settings, but I can not read, nor modify, the actual presets stored in the amplifier. I tried the H&K iOS app on iPad, and the midi application Ctrlr, http://ctrlr.org/hughes-kettner-grandmeister-36/, on MAC OS X and the result is the same.

Any suggestion?

Rgds,
Etienne
