Filter out repetitions of a number Output a number only if it is different from the stored number and will reset the stored number to that differing input number. Alternate modes of operation also identify greater-than or less-than the conditions. Cycling '74 Max Control Repeated to Output if Number Changes TEXT_HERE TEXT_HERE Number if it Changes TEXT_HERE 1 for Logical Transition from 0 to Non-Zero TEXT_HERE 1 for Logical Transition from Non-Zero to 0 TEXT_HERE Set the initial stored value Sets the initial value for comparison to incoming numbers. If there is no argument, the initial value is 0. Set detection mode A second argument may be + or -, a change to mode + or mode -. Subsequent mode messages can change this behavior. Send value if changed The number is sent out the outlet only if it is different from the currently stored value. Replaces the stored value. Send value if changed Outputs the number only if it is different from the currently stored value. Replaces the stored value. Set detection mode Sets the detection mode of change. The word mode, followed by a +, causes change to send a 1 out its left outlet if the received number is greater than the previously received number.
The word mode, followed by a -, causes change to send out a -1 if the received number is less than the previously received number.
The word mode by itself returns change to its default mode of sending out received values that differ from the previously received input. Replace stored value Replaces the stored value without triggering output. Out left outlet: The number received in the inlet is sent out only if it is different from the stored value.

Out middle outlet: If the stored value is 0 and the input is not 0, 1 is sent out; otherwise nothing is sent out.

Out right outlet: If the stored value is not 0 and the input is 0, 1 is sent out; otherwise nothing is sent out.
