Ostinato Live is an audio looping program that lets musicians create multi-layered live musical performances. By recording short, repeating tracks that can be layered, copied, and modified, a single musician can create a complex musical composition.
Each loop, consisting of an arbitrary number of tracks, can be created and saved during a performance or ahead of time, then loaded for seamless, uninterrupted playback.
The straightforward and intuitive user interface ensures basic functionality can be easily accessed. At the same time, the graphical user interface allows for additional features that are not possible with traditional pedal-based options.
