In a short-word, Lambda Music Sequencer is a Scheme interpreter with JACKAudio client as as a MIDI sequencer with an Lisp editor live-coding in mind.
Write Scheme and Make Music by Lamu
Lamu (stands for LAmbda MUsic Sequencer) is a music sequencer which enables users to write music as Scheme programs. In this system, musical notes and other informations are written as Scheme’s association lists. The musical notes can be dynamically sent to the sequencer as Scheme’s association lists on-the-fly. Users can also interact with the dynamically generated music at runtime and affect the direction that the music is going.
Lamu is written in Java and Scheme. It equipped with Kawa a Java based Scheme implementation. You can send MIDI data via JACKAudio Connection Kit a multiplatform audio connection system which is accessed via Java Native Access.
Lamu runs on most major platforms which can run Java such as Windows, Mac-OSX and various Linux distributions.

Lamu works with JACKAudio
JACK(JACK Audio Connection Kit) is a low-latency audio framework which can be used in Linux,Windows and OS X. This enables a number of independent synthesizers, sequencers effectors to work cooperatively. The MIDI signals which Lamu issued are sent to the applications via JACKAudio. Lamu is also able to send JACKAudio commands in order to automate the restoring/destroying connection.

Lamu is equipped with Kawapad
Kawapad is a Lisp editor which is written in Java. Kawapad is a customizable Scheme editor which is able to extend by Scheme itself. It may be a ready customized for editing Scheme code. It is equipped with Kawa a Scheme interpreter; it can execute the Scheme code on-the-fly. Kawapad is embedded in Lamu; though, it can run as a standalone-editor as well.
