Most of the approximately one hundred members are students and alumni from Aalto University, but there are also students from other universities and schools from the greater Helsinki area. The orchestra is conducted by Eero Lehtimäki.
The main events of the year are the autumn and spring concerts in Helsinki area along with the spring tour that is typically headed to different parts of Finland.
