This tracks an incoming signal and outputs the result.

+

The rate controls tell the plugin how quickly to respond to a change in +input. Low values will mean a slower response - a setting of 0 will hold the +last value, and a very high value will track the input exactly.

+

Attack rate is how quickly an upward change is tracked, and Decay for +downward changes. There are two pairs of these - the one used depends on the +level of the Gate.

+

Example uses:

+
    +
  • + An envelope tracker- use the ‘Gate Low’ track rates with + the Gate held low, and run the output through a full-wave rectifier (an ABS() + operator) to get an estimate of the level of a signal.
    • +
  • + Sample and Hold- run a narrow pulse wave into the gate, set the + ‘Gate High’ rates to maximum, and the ‘Gate Low’ + rates set to 0.
    • +
  • + Track and Hold- run a variable pulse wave into the gate, set the + ‘Gate High’ rates to 0, and the ‘Gate Low’ rates set + high. Varying the pulsewidth will vary the time the input is tracked, and + when it is held.
