You can autotune your system following these steps:
- Set the folder permission of
/home/pi/craftbeerpi
to 777 (chmod) (this is to allow a file to be written later) - In the kettle setup, select PIDAutotuneLogic as automatic logic
- Set a temperature setpoint. Usually something between 50°C to 60°C works well.
- Add the amount of water you usually use
- If you use a pump, turn it on
- Enable automatic control (the car symbol)
- Wait until the autotune-logic disables automatic control itself

Then select the Auto-Tune Evo VST and click on the Enable button. Click on the Ok button to confirm changes. Enabling Auto-tune Evo VST plugin; Click on the Effect menu in the menu bar and choose the Auto-Tune Evo VST option at the bottom.

And then go to Preferrence.select Effect and after that select 'edit VST effect folder'.once you press that go to 'auto-scan for VST Directories'.it will scan and (assuming that you have install autotune) it will show you a list of autotune.just press 'OK'.
This can take up to an hour or more (depending on the individual hardware setup and the setpoint temperature), because the autotune logic tries to oscillate around the setpoint.
The problem is, that after overshooting the setpoint, the autotune-logic waits until the temperature drops below the setpoint which usually takes some time.

During tuning, you can read the autotune log by reading the craftbeerpi logfile and filtering for PIDAutotune:
tail -f craftbeerpi/log/name_of_the_logfile | grep PIDAutotune
After the autotune-process is completed successfully, the results will be saved to a file named pidparams.txt in the craftbeerpi working directory (usually:
The autotune-process can fail. In this case, the automatic mode will be disabled, but no pidparams.txt file will be created.If autotune runs forever, the problem is usually either the heater being not powerful enough to reach the setpoint or the temperature not dropping below the setpoint fast enough for whatever reason (isolation, ambient temp. etc.).

Hint: If you aren't sure how auto tuning works, you can do a dry run on this brewing kettle simulation.
- output step %: defines the the output of the autotune-algorithm when stepping up/down, e.g. output step = 100; step up (=heating) output = 100; step down (= cooling) output = -100. This setting should stay at 100%
- lookback seconds: determines how far the algorithm will look back when trying to find local (temperature) extrema (minima/maxima). If the algorithm recognizes even short peaks as extrema, you should increase this value. If it doesn't recognize actual extrema, you should decrease it. Usually the default of 30 seconds work fine.
- max. output %: limits the maximum power output. This is useful if your heater is overpowered and would heat up the kettle way too fast. If you don't want to limit your heater, leave this at the default value of 100%
The PID-tuning rules basically are different ways of calculating the PID-parameters, which changes the behavior of the PID-controller (e.g. ziegler-nichols produces quite a lot of overshoot - not that good for brewing). See Ziegler–Nichols method.In most cases, brewing is the best rule for brewing, obviously ;)

It's rare that a performer can sing flawless vocals in one take. For proof, try listening to a live recording of your favorite band. Most likely, some of the vocals will all be a bit off -- maybe not by much, but just enough that they sound rough when compared to the studio version. Traditionally, studio engineers obtained clean, polished vocals on a song by making the artist record the vocals dozens of times -- then, they edited the best parts together. From Frank Sinatra to Tammi Wynette, laying down multiple vocal tracks in the studio was par for the course.
With Auto-Tune, engineers suddenly didn't need to rely on endless re-recordings to obtain perfect vocals. The singer's last note was a little flat? The engineer simply calls up the full performance on a computer screen and, using a mouse, digitally 'nudges' wrong notes into the right key.

Engineers have been able to change the pitch of a singer's voice ever since magnetic tape was invented. All you have to do is record your voice onto a tape recorder and play it at a faster speed. The problem is, the trick leaves your voice with a high-pitched 'chipmunk' sound. The genius of Auto-Tune is that it can alter the pitch of your voice while still preserving its original quality of the overall recording. Using immense quantities of math, Auto-Tune is able to map out an image of your voice. Using that data, it can then tweak the pitch of your voice without doing too much damage to your voice's original tone and feeling.
The new program saved time and money, and, according to Hildebrand, it made for better music. Here's what Hildebrand told the Seattle Times in 2009:
'Before Auto-Tune, sound studios would spend a lot of time with singers, getting them on pitch and getting a good emotional performance. Now they just do the emotional performance, they don't worry about the pitch, the singer goes home, and they fix it in the mix' [source: Matson].

Within years, 95 percent of all Top 40 songs counted traces Auto-Tune in their production [source: Freeman]. Still, purists derided the software as 'cheating'; artists just weren't taking the time to record quality vocal tracks anymore. American singer-songwriter Neko Case summed it up in a 2006 interview: 'When I hear Auto-Tune on somebody's voice, I don't take them seriously' [source: Dombal].

Worse, Auto-Tune was also accused of filling pop music with attractive yet untalented singers. Only a few years before Cher's 'Believe,' the pop duo Milli-Vanilli had been charged with fraud after audiences discovered that the band's two members had actually been lip-syncing vocals performed by different musicians. Fearing a similar scandal, engineers took pains to disguise their vocal-correction footprints as much as possible.
Meanwhile, buried deep in the software was a setting known as the 'zero function.' One of the ways Auto-Tune makes its pitch-corrections sound natural is by putting small spaces of time in between notes. Just like a real human voice, the software will take a few milliseconds to gently ease from one note to the next. But Auto-Tune came with the option to reducing the space between notes to zero, thereby forcing the notes to change instantaneously from one to the other, giving the vocal track an eerie, computerized timbre.

It was like using Photoshop to dial up a picture to 100 percent brightness. Sure, you could do it, but it would turn your image into a washed-out mess. Similarly, engaging the zero function would transform your vocal track into a clutter of warbly, sci-fi sounds. Surely, the engineers thought at Antares, nobody would ever need to use the zero function. Right?
