Point your iPad or iPhone at the main marker and enjoy playing the fantastic Organotron.
Place the second marker on the left hand side of the main marker to display a score.
The markers have to be placed flat on a surface, e.g. a table. Make sure they are well illuminated. Pointing your iPad`s or iPhone`s camera at the MainMarker, an antique suitcase appears in the same spot. Keep a distance of about a meter between the device and the marker.
To open the suitcase, touch one of its lock with two fingers or the two locks at the same time. The suitcase opens and the Organotron appears, ready to be played.
After placing the second marker besides it you can swipe through the pages of the score, which appears.
Enjoy!
