hi guitarnet,
this issue was not the G2 although some use indeed use the zoom HD as a footswitch. the issue was that i didn't get
a manual worth its name and didn´t know what to search for in the forum.
If you want to connect a MIDI footswitch to your KPA in order to change rig or effects do the following. Connect the MIDI
output of your footswitch to the MIDI input on the rear of your green lunchbox. THEN go to browser mode, choose a patch
of your liking. then touch the system button. you will find 6 pages. go to page four. now "assign" your rig, i.e. "tell" your KPA
to save a connection to the pedal. usually you would begin for instance to assign your favourite rhythm sound to numer
one on the board, but you can do as you like. there are 99 slots available.
this sentence would have saved me four hours of my life. i will post it somewhere else for all the newbies.
thank you
