A note played on any device in a room is heard on every other, through that device's own copy of the patch, a fixed moment after it was played. The player hears themselves at once. Browsers and Groove alike (ADR 0019). A burst of notes does not throw a slow player out of the room. The moment is set by ear, and written down with why. Needs atmosynth.at's rooms and the patch editor to carry notes first.
