mmtss is a loop station built for live performances.
Let’s make music together! This project simplifies a traditional loop tracking station and is designed for interactive collaborative music performances.
The idea: Everybody adds or modifies one “part” of a 32-bar loop. The user gets to play an instrument over the existing mix and record the 32-bar phrase when she or he is ready. Once the person is finished, the project selects another instrument at random for the next viewer to record.
It’s an Ableton Live controller serving a Webkit view, backed by node.js on the backend and socket.io + RaphaelJS on the front. Communication is done through a LiveOSC Live plugin via sockets.

mmtss in practice/playback mode. Here the user is able to practice/mess around with the current instrument to prepare to record the next track.
Pressing “record” puts the user in a wait state. They are prompted to begin recording when all the black boxes count down and disappear.

Modifying the sample project
You can modify this project to suit your own needs. Note that there are two sets of tracks; instrument (MIDI input) tracks and loop tracks that actually store clips.
n tracks, you can add or remove your own instruments. Just make sure that instrument at track
x corresponds to track
Design and architectural inspiration taken from vtouch, a HTML5/Node/Canvas Ableton controller.
You will, however, need to get a license for Ableton Live yourself.
