Boulanger Labs presents csJam—a fun and creative music making app for children and music lovers of all ages. With csJam, you can improvise, perform and compose with a variety of synthetic and sampled instruments. The warm and beautiful sounds of csJam are rendered in real-time using one of the world’s most powerful synthesis and signal processing programs—Csound. csJam offers two sets of live instruments—four melodic and four rhythmic. These can be played along with software generated accompaniment or music composed by the player. Play, sequence, record, save, and share your music—let csJam bring out the composer in you.
