Hi,
I too have a DigiTech Jamman Solo XT.
When I plug in a USB lead from the unit to my Ubuntu linux laptop I see a new /dev/ttyACM0 device appear.
Do you know how to interface to that ?
I presume that is the sort of thing that the JamManager app would use - but there is only a Windows and Mac version of that.
I'm wondering how hard it would be to make a simple Linux command line tool to help upload/download patches etc.
Any ideas?
Regards
Nick Thomas
