Macaw is a great open source sequencer that has a powerful synthesizer that accepts a great variety of plug-ins, MIDI devices and VST plug-ins.

The program is in a rather mature development phase and works very well to compose live music and to play samples.

It has everything that can be demanded from a professional synthesizer, from instrument, sample and sound editors to a sequencer that controls the tracks and the clips to create songs.

The program is full of small details that make it big, like the presence of an icon that shows us the use of the CPU so that we can make sure that the computer doesn't block when we are playing live music, something that is very difficult to accomplish due to the low amount of resources that this program uses.

What's really astonishing is the amount of VST plug-ins and sampler and instrument benches that this program supports. The tracks can be exported to the most used audio formats, even in compressed formats and, of course, those that are most used in the extensive open source community.

An interesting and lightweight, open source sequencer that will fill our computer with the best music notes.
