Sequitur 2.1

Sequitur 2.1: "Sequitur is a BeOS-native MIDI sequencer. It allows you to record, compose, store, and play back music from your computer. It does this by providing you with tools to manipulate MIDI, a protocol that defines standard musical events, such as playing a note or selecting an instrument.

Careful attention has been paid to the interface. It has been designed to be both comfortable for experienced electronic musicians and easy for beginners. Sequitur provides extensive features for manipulating performance data --it allows destructive, non-destructive and even interactive processing. Extreme flexibility is provided through a series of layers. At the top layer, a Sequitur user makes use of tools and MIDI processing facilities provided by the system. As users become more experienced, they can dig deeper into the capabilities, writing their own tools, constructing their own MIDI processing filters, or even writing their own C add-ons."
