Fixed Attributes
These attributes must be set in the object box and determine the behavior of the object at runtime.
mode [enum] (default: default)
Sets the detection mode. By default (0) the left outlet outputs a value if it is different than the previous value. When set to inc, outputs a value of 1 only when the incoming value is greater than the previous value. When set to dec, outputs a value of -1 if incoming value is less than previous value.
Possible values:0 = 'default'
1 = 'inc'
2 = 'dec'
