Audiotool is a browser based music production application that provides everything you need to create music on-line. Music tracks are generated in Audiotool as the output of sequenced arrangements. Audiotool’s arrangements consist of an unlimited number of interconnected devices that generate and process sound. Audiotool’s devices can be externally controlled in real-time via MIDI. Their control’s state can be saved as presets and changes can be automated in a time-line, which also functions as a music sequencer. Arrangements can also use prerecorded audio samples.
