Presets
Presets are a feature of Live that permit you to store the current state of a device. Since it is Live, not Max, that does the saving, the state must be known to Live, which means a preset captures the state of all the parameters you have defined. This means that the value of a number box not connected to a parameter will not be saved -- Live presets are different from the Max preset object in this way.
