Triggered integer counter.
This engine is a counter that outputs numbers, starting at a minimum value, increasing by a step value, and ending with a number that does not exceed the maximum value. It outputs the next number whenever the trigger input is touched. When the maximum number is reached, it starts counting from the beginning again.
At any time the counter can be reset to a specific value by setting the reset input field to that value. The next time the counter is triggered it will start counting from there. Note that the counter will always output numbers based on the min, max and step values, and setting the reset value does not affect those input fields. If the reset value is not a legal counter value, the counter will still behave as though it is.
Each time a counting cycle is started, the syncOut output is triggered. This output can be used to synchronize some other event with the counting cycle.
