It's also possible to connect from iPad to Genos over Wi-Fi.
Genos must be running in Access Point Mode, Genos reference Manual, page 143. (The default password is "00000000". This always fakes me out.)
Then, go to Settings on the iPad and connect to the Genos via Wi-Fi.
Finally, launch Chord Tracker and select Genos as your instrument.
All the best -- pj
