the concept

Not a black box.
Not a bowl of spaghetti.

The Problem - 1

Black Box

You can't see inside. Can't understand why it sounds the way it does. Can't reproduce it intentionally.

The problem - 2

Bowl of Spaghetti

Node graphs and patch cables. Powerful, but slow. You lose creative flow the moment you start drawing wires.

The solution

Glass Rack

Audio flows down the centre. Motion drops left. Control goes right. Map by touching, not drawing. Build a complex instrument in seconds.

why stratum

producers think.
