I used this tutorial http://frontiernerds.com/brain-hack
for converting a MindFlex game into an EEG, I got the who way to the part where you need Processing but now I am stuck. I guess the tutorial is old, I downloaded an old version of Processing (1.5.1) and an old version of ControlP5. I started up Processing and opened Brain_Grapher (folder Processing-Brain-Grapher-master). When I use Present I get the error Cannot find a class or type named "ControlFont"
What am I doing wrong?
