This paper introduces an electroencephalogram (EEG) to the sound transformation tool written in Python and Pure Data using Faust. The proposed signal chain performs a real-time sonification representing the distance of the level from the threshold. We present four different music games implemented in Pure Data using our custom object Scale it in a neurofeedback application. These games were tested and evaluated by users. The subjective impression of the participants (N=53) of gaining control of the game after the session is overall 3.59 on a five-level Likert scale.
