Compo3000 ist ein haptisches Kompositionstool. An der Schnur können verschiedene Kügelchen platziert werden. Zieht man an der Schnur, wird diese eingezogen. Jedes mal wenn eine Kugel im Compo verschwindet ertönt ein Klang. Das ganze könnte man auf mehrere Schnüre Skalieren. So, dass man Notenlinien bespielen könnte.
