Periscope Studio are the makers of the psai ® Interactive Music Engine. psai ® is the first dedicated Interactive Music Engine on Unity. psai ® was designed by videogame composers with a main focus on ease-of-use and musical adaptivity. It enables you to achieve highly interactive music which adapts automatically to your gameplay, whilst making the process of creating and controlling the music as easy and convenient as possible. History As a videogame audio service provider we have always been intrigued by pushing the limits of adaptive videogame music. In collaboration with our clients we have strived towards creating truly interactive soundtracks. It has always been our aim to emotionally connect players with the gameplay and the story in order for them to experience the same rollercoaster of feelings they experience while watching movies. Approaching the concepts of interactive music from a technical point of view, we realized pretty quickly that if you want to achieve truly complex adaptivity, the whole process of creating and then controlling the music soon gets enormously cumbersome. Which is why developers and composers often refrain from it - there have been simply no tools available which are powerful and easy to use at the same time. That is what motivated us in 2008 to start putting our conceptual ideas for interactive videogame music and our experience as composers into the development of psai ®. First we started developing a native version for PC which has since been successfully used in a number of commercial projects. In 2014 we finished porting psai® to the Unity game engine in order to make its features available to a larger audience. psai ® for Unity is completely written in C# without any native code involved, so it works on all of Unity's target platforms, both with the free and the professional version of Unity.
