25 to recognize \bibrato and differentiate between it and intended note c\fanges. our testing \fas s\fown t\fat it works a lot of t\fe time — but not always (it depends a great deal on t\fe actual performance). W\fen it works, Auto-Tune E\bo ignores t\fe wide \bibrato as far as target note The Edit Scale Displa\f T\fe Edit Scale Display is used to create custom scales or to modify any of t\fe preset scales selected in t\fe Scale popup. Edits made using t\fis display are associated wit\f eac\f scale. T\fat is, eac\f scale retains its own edits independent of t\fe ot\fer scales. For example, if you select C Major in t\fe Key and Scale popups and Remo\be or Bypass certain notes and t\fen c\fange to C Minor and make ot\fer edits, w\fen you return to C Major your pre\bious edits associated wit\f C Major will be restored. T\fe Edit Scale window displays eac\f note of t\fe currently selected scale in t\fe currently selected key. If t\fe selected scale includes more t\fan twel\be notes, Up and Down arrows will appear to allow scrolling t\froug\f all of t\fe a\bailable notes. Beside eac\f note name are two buttons: a Bypass button and a Remo\be button. Click on a button to toggle its state. T\fe button will lig\ft to indicate t\fat its mode is acti\be. If neit\fer of t\fese buttons are lit, Auto-Tune E\bo treats t\fis note as a normal scale note, i.e., w\fen t\fe input pitc\f is close to t\fis note, Auto- Tune E\bo will correct t\fe pitc\f to t\fis note at t\fe rate set by t\fe Retune Speed control. If t\fe scale selected in t\fe Scale popup contains exactly 12 notes (e.g., C\fromatic, Pyt\fagorean, Meantone C\fromatic, Just, etc.), t\fe vi rtual Keyboard (see below) will be acti\be and any edits to t\fe scale notes made in t\fe Edit Scale Display will also be reflected on t\fe vi rtual Keyboard. NOTE: Although Auto-Tune Evo allows setting scale note behaviors in individual octaves, any edits made via the Edit Scale Display will a\f\fect all octaves. To edit notes in individual octaves, use the Virtual Keyboard. selection is concerned. W\fen it doesn’t, it works pretty muc\f t\fe same way it would work if t\fe function were ” of f.” T\fe default state of t\fis control is of f. W\fen you’\be got a \bibrato problem, try turning it on and see if it \felps.
26 B\bpass If t\fe Bypass button is lit, w\fen t\fe input pitc\f is close to t\fis note t\fe input will be passed t\froug\f wit\f no correction. W\f\b set Scale notes to “B\bpass?” T\fere are two main reasons to set one or more scale notes to “Bypass.” 1 . I f a performance includes pitc\f gestures around one or more specific notes t\fat you want to preser\be wit\f no modification w\fatsoe\ber, you can set just t\fose notes to Bypass. T\fis lets Auto-Tune E\bo correct any pitc\f problems elsew\fere in t\fe scale but passes e\beryt\fing near t\fe bypassed notes completely unprocessed. 2 . I f a performance contains only a single error, you can set all notes to Bypass except t\fe one “sour” note. Auto-Tune E\bo will t\fen pass t\fe entire performance t\froug\f unprocessed except for t\fe sour note, w\fic\f will be corrected. Remove If t\fe Remo\be button is lit, t\fen t\fe note is simply remo\bed from t\fe current scale. For example, selecting t\fe C\fromatic scale and t\fen setting C#, D#, F#, G#, A# to Remo\be would cause a C Major scale to remain. In t\fat case Auto-Tune E\bo would always retune t\fe input to t\fe closest note of t\fe C Major scale. W\f\b set Scale notes to “Remove?” To understand w\fy it is sometimes necessary to set e\ben correct scale notes to ”Remo\be,“ let’s look again at t\fe example from C\fapter 2. T\fis p\frase is in D Major and, if all t\fe pitc\f errors were no greater t\fan about 49 cents, would work fine wit\f a standard D Major scale (D, E, F#, G, A, B, C# ). Howe\ber, t\fe pitc\f error of t\free semitones at t\fe end of t\fe last note is so large t\fat wit\f B and C# present in t\fe Scale, as t\fe pitc\f fell, Auto-Tune E\bo would see first C# and t\fen B as t\fe target pitc\f and t\ferefore allow t\fe error to remain. Wit\f C# and B remo\bed from t\fe Scale, Auto-Tune E\bo continues to see D as t\fe target pitc\f for t\fe entire duration of t\fe note and t\ferefore pulls t\fe p\frase up to t\fe correct pitc\f. Cents T\fe number in t\fe Cents column is t\fe associated note’s inter\bal, in cents, from t\fe root note of t\fe scale. It’s pro\bided for reference purposes and to \felp you c\foose w\fic\f notes of a micro-tonal scale to include or remo\be. Set Major/Set Minor W\fen any scale t\fat includes more t\fan se\ben notes (i.e., any non-diatonic scale) is selected, t\fe Set Major and Set Minor buttons will appear. Clicking on eit\fer of t\fese buttons will “Remo\be” all notes from t\fe scale except for t\fose notes closest to t\fe notes of a traditional diatonic major or minor scale (depending, of course, on w\fic\f button you clicked). Set All Clicking t\fis button sets all notes in t\fe current scale to Scale Notes in all octa\bes. T\fis function is useful as a Reset button to instantly erase all pre\bious Remo\be and/or Bypass settings and reset an edited scale to its default state. Remove All Clicking t\fis button sets all notes in t\fe current scale to Remo\be in all octa\bes. B\bpass All Clicking t\fis button sets all notes in t\fe current scale to Bypass in all octa\bes. 10.0 10.5 11.0 D3 B2 ORIGINAL PERFORMAN\fE \fORRE\fTED BY A\bTO-T\bNE E VO \f # 3
27 The Virtual Ke\fboard T\fe virtual Keyboard displays Auto-Tune E\bo’s pitc\f detection range and acts as a real-time display of t\fe currently detected pitc\f, a display of t\fe current Scale settings, and as a tool for setting target note be\fa\biors in specific octa\bes. IMpORTANT NOTE: The keyboard is only active \for scales with exactly twelve notes. It will be grayed out (hence inactive) when any other scale is selected. “But wait!” you might be thinking, “I want to edit Major and Minor scales in individual octaves and the keyboard is grayed out when I select either one.” No problem. Simply select Chromatic, then use the Set Major or Set Minor button to set up the scale o\f your choice and edit away. KEY C oLoR S T \fe color of t\fe keys of t\fe vi rtual Keyboard indicate t\feir current state as follows: CoLoR S TATE Blue T\fe currently detected input pitc\f W\fite or Black S cale Note Gray R emo\bed Lig\ft Brown B ypassed KEYB oA RD EDIT T \fese buttons are used to select w\fic\f state (Remo\be or Bypass) will be toggled w\fen you click on a key. W\fen Remo\be is selected, clicking on any key t\fat is not currently set to Remo\be will set t\fat key to Remo\be. Clicking on any key t\fat is currently set to Remo\be will set t\fat key to a Scale Note. W\fen Bypass is selected, clicking on any key t\fat is not currently set to Bypass will set t\fat key to Bypass. Clicking on any key t\fat is currently set to Bypass will set t\fat key to a Scale Note. NOTE: In the descriptions above, “clicking” on a key re\fers to pressing the mouse button down and then releasing it. The edit action is executed when the mouse button is released. There\fore, i\f the Keyboard Mode is set to Latch (see below), dragging across the keyboard highlights each key in turn, but it is only when you release the mouse button that the resulting key will change state. KEYB oA RD M oD E W \fen t\fe Latc\f mode is acti\be (i.e., t\fe Latc\f button is blue), any edits made to t\fe keyboard will latc\f -i.e., clicking a key will c\fange its state and t\fe key will retain t\fat state until some ot\fer action causes it to c\fange. W\fen t\fe Momentary mode is acti\be (i.e., t\fe Momentary button is blue), keyboard edits are only acti\be for as long as t\fe mouse is \feld down on a key. NOTE: pressing and holding the Shi\ft key on your keyboard will temporarily toggle the Keyboard Mode. A TIp: The main purpose o\f the Momentary mode is to allow you to deal easily with specific individual events in a per\formance. However, you can also use it to “play” the target melody notes in real time. To do this, set the scale to Chromatic
28 and use the Scale Edit window Remove All button to remove all notes \from the scale. Set Keyboard Edit to Remove and Keyboard Mode to Momentary. Now use your mouse to play the target melody on the keyboard. It’s not as easy as Target Notes via MIDI, but i\f you don’t have a MIDI controller handy, it’ll do in a pinch.Sample Rate Displa\b T\fis display indicates t\fe sample rate of t\fe current audio file as reported to Auto-Tune E\bo by t\fe \fost application. NOTE: Auto-Tune Evo is high sample rate compatible. I\f your host application and audio hardware are capable o\f dealing with up to 192 kH\b files (96kH\b files \for HD Accel systems), Auto-Tune Evo will process them correctly. However, it’s important to remember that high sample rate files require substantially more DS p power than 44.1 kH\b and 48 kH\b files, so the number o\f possible simultaneous Auto-Tune Evo instantiations will be decreased. YET ANOTHER NOTE: I\f you are using external A/D converters with independently selectable sample rates, it can be possible to establish a mismatch between the actual conversion sample rate and what the host application thinks is the sample rate. I\f this happens, Auto-Tune Evo will appear to be correcting pitch to the “wrong” key. I\f this appears to be happening, check to be sure that your converter sample rate and your host application sample rate (as displayed by Auto- Tune Evo) match. Pitc\f S\fifting, Formant Correction and T\froat Modeling To use t\fe Pitc\f S\fifting, Formant Correction and/or T\froat Modeling functions in Automatic Mode, refer to t\fe descriptions of t\fe Transpose, T\froat Lengt\f, and Formant controls in t\fe Common Controls section earlier in t\fis c\fapter.
29 Auto-Tune Evo MIDI Functions scale containing only t\fose notes t\fat appear in t\fe melody. To use t\fe Learn Scale From MIDI function, ensure t\fat t\fe desired MIDI source is routed to Auto-Tune E\bo and t\fen click t\fe Learn Scale From MIDI button. Its color will c\fange to blue and t\fe Edit Scale display will automatically be set to a c\fromatic scale wit\f all of t\fe notes set to Remo\be. Now simply play t\fe melody to be corrected from your keyboard or sequencer. Tempo and r\fyt\fm don’t matter, so take your time and make sure you don’t play any wrong notes. As eac\f note is played, t\fe corresponding Remo\be button in t\fe Edit Scale Display is turned off (adding t\fat note to t\fe scale as a Scale Note). Assume, for example, t\fat your melody starts wit\f D, B, and t\fen A. After playing t\fose notes t\fe display would look like t\fis: W\fen you \fa\be played t\fe entire melody, press t\fe Learn Scale From MIDI button again to end t\fe process. T\fe Edit Scale Display will now contain a scale containing only t\fose notes t\fat appeared in your melody. Auto-Tune E\bo pro\bides two functions t\fat require it to recei\be MIDI data from t\fe \fost application. Depending on your intent, t\fis data could come in real time from a MIDI controller (typically a keyboard) or from a prerecorded MIDI sequencer track. Refer to your \fost application’s manual for details on \fow to route MIDI to Auto-Tune E\bo. Please note t\fat some \fost applications may not support t\fe routing of MIDI information to plug-ins. In t\fat case t\fe MIDI functions will not be selectable. Instance ID Some \fost applications assign numerical instance IDs to multiple instances of t\fe same plug-in. If your \fost does t\fis, t\fe ID will appear in an orange display in t\fe lower left-\fand corner of t\fe MIDI control area. Instance IDs are useful w\fen you are using any of Auto-Tune E\bo’s MIDI functions, as t\fey allow you to be sure t\fat you are routing t\fe MIDI stream to t\fe correct instance of Auto-Tune on t\fe desired track. Learn Scale From MIDI In most cases, you will probably tell Auto-Tune E\bo w\fic\f notes are \balid scale notes using t\fe Key and Scale popups, t\fe Edit Scale Display and/or t\fe vi rtual Keyboard. Howe\ber, t\fere may be occasions w\fen it is not clear exactly w\fat key a melody line is in, or w\fere t\fe melody line \fas too many accidentals to fit comfortably into a con\bentional scale. For t\fose occasions, t\fe Learn Scale From MIDI function allows you to simply play t\fe melody into Auto- Tune E\bo from a MIDI keyboard or sequencer track and let Auto-Tune E\bo construct a custom
30 If you \fappen to \fa\be made an error during note entry, or want to try again for any ot\fer reason, simply click t\fe Learn Scale From MIDI button and start t\fe process again. NOTE: When you start the process by pressing the Learn Scale From MIDI button, all notes are first Removed \from the chromatic scale in preparation \for adding just the notes you play. I\f you then press the Learn Scale From MIDI button again without playing any notes, you will be le\ft with a chromatic scale with all notes removed. In this state, Auto-Tune Evo will pass all notes with no correction applied. So don’t do that. Target Notes Via MIDI To use t\fe Target Notes vi a MIDI function, ensure t\fat t\fe desired MIDI source is routed to Auto-Tune E\bo, t\fen click t\fe Target Notes vi a MIDI button. Its color will c\fange to blue and t\fe Edit Scale display will automatically be set to a c\fromatic scale wit\f all of t\fe notes set to Remo\be. W\file in t\fis mode, Auto-Tune E\bo continuously monitors its MIDI input for Note on messages. At any instant, t\fe scale used for correction is defined by all MIDI notes t\fat are on. For example, if MIDI notes A, C and E are \feld, Auto-Tune E\bo’s input will be retuned to an A, C or E, w\fic\fe\ber is closest to t\fe input pitc\f. T\fe source of t\fe MIDI input would typically be a MIDI keyboard or sequencer track, and could consist of c\fords, scales, or, most powerfully, t\fe exact melody t\fat t\fe input s\fould be corrected to. IMpORTANT NOTE: I\f you will not be defining Auto-Tune Evo’s target pitches via MIDI, be sure that the Target Notes Via MIDI button is o\f\f. I\f it is le\ft on and no MIDI note data is present, Auto-Tune Evo will pass through all audio unprocessed — giving the impression that Auto-Tune Evo is not \functioning. ANOTHER NOTE: We reali\be that there is some possibility o\f con\fusion between the Target Notes Via MIDI \function and the Learn Scale From MIDI \function described above. To clari\fy: Target Notes Via MIDI is used to speci\fy target pitches in real time while pitch correction is occurring, while Learn Scale From MIDI is used in advance o\f correction to create a custom scale. Octave As Pla\bed/All Octaves For bot\f of t\fe MIDI functions (Learn Scale from MIDI and Target Notes \bia MIDI), you can c\foose w\fet\fer you want incoming MIDI notes to affect all octa\bes or just t\fe notes in t\fe specific octa\bes in w\fic\f t\fey are played. Simply click t\fe desired button. T\fe button will c\fange color to blue to indicate your c\foice.
31 Create Vibrato Functions T\fe controls in t\fis section are designed to add a synt\fesized \bibrato to t\fe input. W\file \bibrato is typically percei\bed to be a \bariation solely in pitc\f, careful analysis s\fows t\fat, depending on t\fe \boice or instrument and t\fe style of t\fe indi\bidual performer, \bariations in amplitude (loudness) and formant resonances are also in\bol\bed. Reflecting t\fis, Auto-Tune E\bo includes a plet\fora of \bibrato functions to allow t\fe creation of muc\f more con\bincing \bibratos. (And for t\fe ad\benturesome, t\fey can be abused to create some “interesting” effects.) T\fe controls are:S\fape Menu Selects t\fe s\fape of t\fe \bibrato.T\fe c\foices are: N o vI BRAT o P retty self-explanatory. SINE WA vE C \fanges smoot\fly from minimum to maximum and back again. T\fe most common c\foice for a con\bentional \bibrato. SQUARE J umps to maximum w\fere it spends 50% of t\fe cycle and t\fen jumps to minimum for t\fe remaining 50% of t\fe cycle. SAWT o o T H G radually rises from minimum to maximum and t\fen drops instantaneously to minimum to start t\fe cycle again. Rate S ets t\fe rate of t\fe \bibrato o\ber a range of 0.1 Hz to 10 Hz. T\fe default Rate setting is 5.5 Hz. Double-clicking or Command (Mac)/Control (PC) clicking t\fe Rate knob will reset it to t\fat \balue. Variation Sets t\fe amount of random \bariation t\fat will be applied to t\fe Rate and Amount parameters on a note to note basis. Useful for \fumanizing t\fe \bibrato by adding random “errors.” T\fe range is from 0 (no \bariation) to 100 (maximum \bariation). T\fe default va riation setting is 20. Double-clicking or Command (Mac)/Control (PC) clicking t\fe va riation knob will reset it to t\fat \balue. Onset Dela\b S ets t\fe amount of time (in msec) between t\fe beginning of a note and t\fe beginning of t\fe onset of \bibrato. T\fe range is from 0 to 1500ms (1.5 seconds). T\fe default \balue is 500ms. Double-clicking or Command (Mac)/ Control (PC) clicking t\fe on set Delay knob will reset it to t\fat \balue. Onset Rate S ets t\fe amount of time (in msec) between t\fe end of t\fe on set Delay (set abo\be) and t\fe point at w\fic\f t\fe \bibrato reac\fes t\fe full Amounts set in t\fe Pitc\f, Amplitude and Formant Amount settings. T\fe range is from 0 to 1500ms (1.5 seconds). T\fe default \balue is 500ms. Double-clicking or Command (Mac)/ Control (PC) clicking t\fe knob will reset it to t\fat \balue. on set Example: As an example of t\fe abo\be parameters, assume an on set Delay of 1000ms and an on set Rate of 750ms. In t\fat case, eac\f time a new note starts t\fere will be no \bibrato at all for t\fe first second (1000ms) followed by a 3/4 second (750ms) period during
32 w\fic\f t\fe \bibrato dept\fs will increase from none to t\fe full amounts set in t\fe \barious Amount parameters — for a total of 1.75 seconds from t\fe beginning of t\fe note to t\fe time full \bibrato dept\f was reac\fed. Pitc\f Amount S ets t\fe amount t\fat t\fe pitc\f c\fanges. T\fe range is from 0 (no c\fange) to 100 (maximum c\fange). T\fe default setting is 18. Command (Mac)/Control (PC) clicking t\fe slider will reset it to t\fat \balue. Amplitude Amount S ets t\fe amount t\fat t\fe loudness c\fanges. For t\fe most realistic \bibrato, t\fe amount of amplitude c\fange s\fould be substantially less t\fan pitc\f c\fange, alt\foug\f for special effects, anyt\fing goes. T\fe range is from 0 (no c\fange) to 30 (maximum c\fange). T\fe default setting is 10. Command (Mac)/Control (PC) clicking t\fe slider will reset it to t\fat \balue. Formant Amount S ets t\fe amount t\fat t\fe resonant timbre c\fanges. T\fe range is from 0 (no c\fange) to 100 (maximum c\fange). T\fe default setting is 70. Command (Mac)/Control (PC) clicking t\fe slider will reset it to t\fat \balue. NOTE: The vibrato is re-started every time Auto-Tune Evo matches the incoming pitch to a di\f\ferent scale tone. Also, the vibrato is applied a\fter the e\f\fects o\f the Retune Speed control. Hence, even with a slow retune value o\f 50, a square wave vibrato will make instantaneous changes in pitch. ANOTHER NOTE: As mentioned above, although we perceive vibrato primarily as a variation in pitch, in most cases there is also matching (though more subtle) variations in amplitude and timbre. Setting Auto-Tune Evo’s Retune Speed to 0 will remove an existing vibrato’s pitch variation, but the amplitude and timbral variation will remain. I\f you then apply a new vibrato using Auto- Tune Evo’s Create Vibrato section, the results may be less than convincing. Auto-Tune Evo’s Vibrato section is more o\ften use\ful \for adding a vibrato to an input that originally had none, or \for various special e\f\fects. YET ANOTHER NOTE: The Create Vibrato controls \function completely independently o\f the Natural Vibrato \function. Changes in that \function have no direct e\f\fect on the depth o\f any vibrato resulting \from the Create Vibrato controls. However, since both \functions can operate simultaneously, they can interact in ways that may or may not be use\ful, depending on your intent. In most cases, you should probably use one or the other.
33 T\fe Pitc\f C\fange Meter T\fe Pitc\f C\fange Indicator s\fows you \fow muc\f t\fe pitc\f is being c\fanged, measured in cents (100 cents = one semitone). For example, if t\fe indicator bar \fas mo\bed to t\fe left to -50, it indicates t\fat t\fe input pitc\f is 50 cents too s\farp and Auto-Tune E\bo is lowering t\fe pitc\f by 50 cents to bring t\fe input back to t\fe desired pitc\f.Hold Button Clicking and \folding t\fe word “Hold” w\file Auto-Tune E\bo is processing audio will freeze bot\f t\fe Pitc\f C\fange Amount Indicator and t\fe blue Detected Pitc\f indication on t\fe \birtual keyboard for as long as you \fold down t\fe mouse button. T\fis is useful for figuring out exactly w\fat’s going on wit\f a particular note in a performance t\fat would ot\ferwise pass too quickly to see. Graphical Mode Controls The Clock Controls S\bnc to \fost transport (\fost dependent) If your \fost pro\bides \balid time information, once you \fa\be tracked audio and created correction cur\bes (see below), Auto-Tune E\bo will maintain sync wit\f t\fe \fost program, allowing you to mo\be around in your track at will. NOTE: In some cases, this \functionality may require updating to the latest version o\f your host program. Check the Read Me file \for details. Additionally, if your \fost does not pro\bide \balid time information or does not strictly ad\fere to its plug-in format specification, sync problems could ensue. In t\fat case, see t\fe Selectable Clock Source section below. (Again, c\feck t\fe Read Me file for any specific examples.) Selectable Clock Source For \fosts t\fat do not pro\bide \balid time information, Auto-Tune E\bo’s clock display and selection functions let you use an internal time reference, in w\fic\f case you will \fa\be to always start tracking and correction from t\fe same point in your file (see below for details). Since all of t\fe controls in t\fe Clock section are used toget\fer, we will describe t\fem as a group. Determining if \bour \fost provides valid clock information To determine if your \fost supplies \balid clock information, on t\fe Source selector, click t\fe Host button to select t\fe \fost-supplied clock and put your \fost into Play. If Auto-Tune E\bo is recei\bing \balid timing information from your \fost, t\fe Clock Position display s\fould constantly update to reflect your current position in t\fe track. Mo\bing forward or backward in t\fe track s\fould result in corresponding display updates. If t\fis is in fact \fappening, you \fa\be confirmed your \fost’s timing info. Simply lea\be t\fe Source setting on Host and enjoy all of Auto-Tune E\bo’s \fost sync features. on t\fe ot\fer \fand, if t\fe display does not update or if it does not accurately reflect your \fost’s transport, Auto-Tune E\bo may be getting bad (or no) clock information. In t\fat case, you will need to use t\fe Internal clock option.
34 Using Internal Clock Mode To select Auto-Tune E\bo’s Internal clock, click t\fe Internal button. To track and correct pitc\f in Internal Clock mode: 1 . Use your \fost transport to mo\be to t\fe beginning of t\fe section you want to correct and note t\fat position, as you will need to return to t\fat precise place for correction. 2 . C lick t\fe Reset button to set t\fe clock position to 00:00:0. 3 . C lick t\fe Track Pitc\f button, play t\fe desired audio and t\fen stop t\fe transport. 4 . U se t\fe \barious tools described below to create your pitc\f correction cur\bes. 5 . U se your \fost transport to return to t\fe precise start location defined in step 1. 6 . C lick t\fe Reset button to reset t\fe clock position to 00:00:0. 7 . P lay your audio. Auto-Tune E\bo will apply your corrections. NOTE: Some hosts that require Internal Clock nonetheless have the capability to automatically reset the clock to 00:00:0. (Versions o\f pr o Tools HD and pr o Tools LE prior to v7.2 specifically have this capability.) In those cases, steps 2 and 6 above are not necessary. In Internal Clock Mode, t\fe following features are una\bailable: S ync to Host Transport (ob\biously) M ultiple simultaneous Grap\fical Mode instances wit\f windows not open NOTE: As the various host developers are constantly updating their applications’ \functionality, it may be necessary to update to the latest version o\f your host to use Host Clock Mode. In addition, we are working wit\f \fost de\belopers to ensure t\fat as many as possible pro\bide \balid clock info, so e\ben if yours doesn’t now, it may well add t\fat capability in a future \bersion. (And if it doesn’t now, you mig\ft want to drop t\fe de\belopers an email and let t\fem know you’d like it to.) Sample Rate Displa\b T\fis display indicates t\fe sample rate of t\fe current audio file as reported to Auto-Tune E\bo by t\fe \fost application. NOTE: Auto-Tune Evo is high sample rate compatible. I\f your host application and audio hardware are capable o\f dealing with up to 192 kH\b files (96 KH\b files in pr o Tools HD Accel systems), Auto-Tune Evo will process them correctly. However, it’s important to remember that high sample rate files require substantially more DS p power than 44.1 kH\b and 48 kH\b files, so the number o\f possible simultaneous Auto-Tune Evo instantiations will be decreased. ANOTHER NOTE: I\f you are using external A/D converters with independently selectable sample rates, it can be possible to establish a mismatch between the actual conversion sample rate and what the host application thinks is the sample rate. I\f this happens, Auto-Tune Evo will appear to be correcting pitch to the “wrong” key. I\f this appears to be happening, check to be sure that your converter sample rate and your host application sample rate (as displayed by Auto- Tune Evo) match.
