I think he meant the Line 6 floorboard
Ahh..!
I know that Line6 have been pushing this as a feature, using the USB to control any Midi compatible application, like using it to start/stop recording in Logic/Pro Tools. Basically anything that listens to Midi control messages can be controlled by the Shortboard.
The thing that makes it possible is that the Shortboard MKII is designed as a 'Class Compliant' USB midi device, so no drivers are necessary.
And that is the prerequisite for the Kenton box to work too.
I've seen a lot of posts were people are controlling non-Line6 stuff via midi, but it has always been either:
Shortboard -> USB -> Computer -> Midi -> device
OR
Shortboard -> R45j -> Line6 Amp -> Midi -> Device.
I guess one could use an old PodXT as a translator too, You could probably pick one up second-hand for the same price as the Kenton box.
