Please be sure that you're using a compatible DAW, and that you've installed the correct plugin format for your DAW. The latest versions of all Antares plug-ins can be downloaded from the Software Downloads page. (Older discontinued Antares plug-ins can be downloaded from the Discontinued Software page).
Response To Auto Tune Challenge 2016
Autotune in not showing up in my DAW Program; I’m getting alot of latency when I use Autotune Evo or AVOX2 in Logic. Most of my other plugins do not have this problem. How does the Auto-tune Challange Response authorization work? How do I authorize my AVOXAT, Autotune, AVOX on my PC.
Some DAWs may also require you to manually scan the plug-in folder in order for your plug-ins to appear. Please consult your DAW's documentation for more information about how to do that.

Plot System Responses
To determine whether the compensator design meets your requirements,you can analyze the system response using the response plots. On the PIDTuner tab, select a response plot from the AddPlot menu. The Add Plot menu alsolets you choose from several step plots (time-domain response) orBode plots (frequency-domain response).
![Response Response](https://www.isa.org/uploadedImages/Content/Standards_and_Publications/ISA_Publications/InTech_Magazine/2016/Mar-Apr/MA-2016-auto-basics-fig1.jpg)
For 1-DOF PID controller types such as PI, PIDF, and PDF, the software computes system responses based upon the following single-loop control architecture, where G is your specified plant and C is the PID controller:
For 2-DOF PID controller types such as PI2, PIDF2, and I-PD, the software computes responses based upon the following architecture:
The system responses are based on the decomposition of the 2-DOF PID controller, C, into a setpoint component Cr and a feedback component Cy, as described in Two-Degree-of-Freedom PID Controllers (Control System Toolbox).
The following table summarizes the available responses for analysis plots.
Response | Plotted System (1-DOF) | Plotted System (2-DOF) | Description |
---|---|---|---|
Plant | G | G | Plant response. Use to examine plant dynamics. |
Open-loop | GC | –GCy | Response of the open-loop controller-plant system. Use for frequency-domain design. Use when your design specifications include robustness criteria such as open-loop gain margin and phase margin. |
Reference tracking | (from r to y) | (from r to y) | Closed-loop system response to a step change in setpoint. Use when your design specifications include setpoint tracking. |
Controller effort | (from r to u) | (from r to u) | Closed-loop controller output response to a step change in setpoint. Use when your design is limited by practical constraints, such as controller saturation. |
Input disturbance rejection | (from d1 to y) | (from d1 to y) | Closed-loop system response to load disturbance (a step disturbance at the plant input). Use when your design specifications include input disturbance rejection. |
Output disturbance rejection | (from d2 to y) | (from d2 to y) | Closed-loop system response to a step disturbance at plant output. Use when you want to analyze sensitivity to modeling errors. |
Compare Tuned Response to Block Response
By default, PID Tuner plots system responses usingboth:
- The PID coefficient values in the controller block in the Simulink® model (Block response).
- The PID coefficient values of the current PIDTuner design (Tuned response).
As you adjust the current PID Tuner design, suchas by moving the sliders, the Tuned response plots change, while theBlock response plots do not.
To write the current PID Tuner design to the Simulink model,click . When you do so, thecurrent Tuned response becomes the Block response. Further adjustmentof the current design creates a new Tuned response line.
To hide the Block response, click Options,and uncheck Show Block Response.
