Device Parameters in Max for Live
Parameters are settings of Max for Live devices you want to store and/or automate in Live. In some cases, a parameter may be set once and never change. In other cases, you'll want to use Max objects to interact with parameter values by clicking and moving the mouse, by receiving MIDI data mapped to a parameter, or via Live automation.
There are two ways to add parameters to your device: using the Live UI objects or using pattr objects with parameter mode enabled.
The Parameters Window shows all parameters currently associated with a device, and permits you to change parameter attributes in a single place. You can also change parameter attributes for individual objects by using the Parameter tab of the inspector.

Parameter Names
Max for Live provides several ways to name a parameter in a device, each of which is an Attribute. that can be set using an object's Inspector. These names can be set separately or linked together, and they serve several useful purposes.
You can use a single name for all three of these attributes by checking the Link to Scripting Name attribute in the object's Inspector. You may find this to be a simple approach to managing paramter naming.

Setting the display name for a parameter
Note: If your short name is too long, it will be automatically truncated. If you are using a live.slider or live.gain~ object, you can use resize the object manually by clicking in the lower right-hand corner of the object and dragging. If you are using a live.dial object, you should enter a new horizontal value for the Patching Rectangle or Presentation Rectangle attributes using the object's Inspector.
