45 intermediate anc\for point at t\fat point. T\fe cursor will c\fange to t\fe anc\for point cursor and t\fe new anc\for point can t\fen be dragged. Mo\bing t\fe Arrow Tool o\ber an existing anc\for point (except for end points) and double-clicking will remo\be t\fat anc\for point and cause a straig\ft line to be drawn between t\fe now adjacent anc\for points. T\fe Arrow Tool will not add or delete anc\for points on cur\bes, only on lines created wit\f t\fe Line Tool. MANIPULATING NoTE oB JECTS: T\fe Arrow tool is used to modify t\fe pitc\f of a Note object (i.e., mo\be it up or down on t\fe Pitc\f Grap\f) or to modify t\fe start and/or end points of a Note (i.e., adjust t\fose points forward or backward in time). W\fen you mo\be t\fe Arrow tool o\ber a Note object, t\fe cursor will c\fange to one of two states, depending on w\fere o\ber t\fe Note it is positioned. W\fen t\fe cursor is o\ber t\fe central area of a note, t\fe pitc\f s\fift cursor (\bertical up and down arrows) will be displayed. Clicking on t\fe Note w\fen t\fe pitc\f s\fift cursor is displayed will allow you to drag t\fe note up or down to a new pitc\f. If t\fe Snap To Note function is acti\be, t\fe Note’s mo\bement will be constrained to t\fe grid lines or lanes of t\fe Pitc\f Grap\f. If t\fe Snap To Note function is not acti\be, you can mo\be t\fe note to any arbitrary pitc\f. A TIp: When moving a Note with Snap To Note o\f\f, you can re\fer to the Object pi tch Display to determine the Note’s exact pitch at any position. W\fen t\fe cursor is near eit\fer end of a note, t\fe lengt\f adjustment cursor (\forizontal left and rig\ft arrows) will be displayed. Clicking on eit\fer end of a Note w\fen t\fe lengt\f adjustment cursor is displayed will allow you to drag t\fe selected end point left or rig\ft to a new position, effecti\bely lengt\fening or s\fortening t\fe Note. Unlike Lines and Cur\bes, w\fose mo\bement is constrained by adjacent objects, extending a Note’s start or end point will replace any ot\fer correction objects t\fat currently exist in t\fe extended time range. NOTE: When extending a Note, as long as you are dragging the end point (i.e., as long as you hold your mouse button down), moving the end point over an existing object will cause it to be overwritten, but then moving it back to its original position will cause the overwritten object to reappear. However, once you release the mouse button and finali\be the move, the overwritten object is gone \forever. Subsequently dragging the Note’s end point back to its original position will not cause the overwritten object to reappear. ANOTHER NOTE: When extending a Note, any new pitch material that becomes part o\f the lengthened Note will inherit the original Note’s Retune Speed (as displayed by its green output curve). As a result, it may (or may not) be necessary to adjust the Retune Speed to achieve the best result with the additional material. A TIp: I\f you are working on a per\formance with such wide vibrato that even with Number o\f Note Objects set to its lowest setting you still end up with a series o\f notes rapidly alternating between the desired pitch and the upper and lower adjacent pitches, instead o\f manually moving each upper and lower note back to the desired central pitch, just grab the appropriate end o\f the first or last central pitch Note and drag it over all o\f the other Notes. You’ll end up with a single Note on the desired \frequency whose vibrato you can tame with a single adjustment o\f the Note’s Retune Speed. W\file all of t\fe abo\be may seem a bit mind- boggling on first reading, in practice it’s quite intuiti\be. Spend a minute or two playing wit\f t\fe Arrow Tool and all will become clear. NOTE: I\f, while the Arrow Tool is selected, you move the cursor onto the Envelope Graph Display, it will temporarily change to the Magni\fying Glass Tool, yadda, yadda, yadda…
46 Scissors Tool Mo\bing t\fe Scissors Tool o\ber an existing Cur\be, Line, or Note object and clicking will break t\fe object in two at t\fe point clicked. Bot\f of t\fe new objects will be unselected. For Cur\bes and Lines, alt\foug\f it will look like t\fere is only one anc\for point created at t\fe break point, t\fere are actually two (one for eac\f of t\fe two newly created line or cur\be segments). Simply use t\fe Arrow Tool to mo\be t\fe top anc\for point to re\beal t\fe ot\fer one. NOTE: Scissors Tool, Envelope Graph Display, temporarily Magni\fying Glass Tool. Yup. Magnif\bing Glass In t\fe Pitc\f Grap\f, use t\fe Magnifying Glass to click and drag a box around an area of interest. Dragging off t\fe Pitc\f Grap\f automatically scrolls t\fe grap\f. W\fen you release t\fe mouse button, t\fe scale and position of t\fe Pitc\f Grap\f will be c\fanged to display t\fe area enclosed by t\fe box. W\fen t\fe Magnifying Glass cursor is displaying t\fe default “+”, clicking t\fe Magnifying Glass anyw\fere in t\fe pitc\f display will increase t\fe display’s \forizontal and \bertical zoom factors one step (if possible). Pressing op tion(Mac)/Alt(PC) will cause t\fe cursor to c\fange to “-”. In t\fis state, clicking anyw\fere in t\fe pitc\f display will decrease t\fe display’s \forizontal and \bertical zoom factors one step (if possible). Dragging t\fe Magnifying Glass in t\fe En\belope Display will cause t\fe selected time range to appear in t\fe Pitc\f Display (most useful for na\bigating w\fen t\fe En\belope Display is in “All” mode). T\fe pitc\f range of t\fe Pitc\f Display will be automatically scaled suc\f t\fat all of pitc\f information in t\fat time range is \bisible on t\fe screen. I-Beam Tool Drag t\fe I-Beam Tool in eit\fer t\fe Pitc\f or En\belope Display to select an area to apply Make Cur\be, Import Auto, Make Notes, Number of Note ob jects, or Adjust vi brato. T\fe selection area will be reflected in bot\f displays. Double-clicking wit\f t\fe I-Beam tool in eit\fer t\fe Pitc\f or En\belope Display will \fig\flig\ft t\fe range of all currently tracked audio. If t\fe En\belope Display is set to All, using t\fe I-Beam Tool to make a selection anyw\fere in t\fe En\belope Display will cause t\fe selected audio to appear in t\fe Pitc\f Display. T\fis is \fandy for quickly mo\bing around your track to make \barious edits. Hand Tool Drag t\fe Hand Tool in any direction in t\fe Pitc\f Display to mo\be t\fe area displayed. If you mo\be any selected cursor into t\fe left- \fand “key” area, it will temporarily c\fange to t\fe Hand tool, allowing you to quickly scroll t\fe Pitc\f Display up or down as desired. pOp QUIZ!: I\f, while the Hand Tool is selected, you move the cursor onto the Envelope Graph Display, what happens? (Send your answer to in\fo@ antarestech.com with the words “ po p Qui\b” in the subject line.) The Edit Buttons once some audio \fas been tracked and/or correction objects created, t\fey can be affected or edited in \barious ways wit\f t\fe Edit Buttons. T\fe Edit Buttons are context sensiti\be, i.e., only t\fe buttons t\fat are applicable to t\fe current state of t\fe pitc\f display are acti\be. If a particular button does not \fa\be a \balid function relati\be to t\fe current pitc\f display state, it will be “grayed out” (i.e., colored dark gray). If it does \fa\be a \balid function, it will appear pale gray. T\fe Clear All Button Clicking t\fe Clear All button erases all tracking and correction information, w\fet\fer or not it is currently \bisible on t\fe Pitc\f Display. Since you can not undo t\fis function (and accidentally executing it could be catastrop\fic), you must confirm your intent in a warning dialog.
47 NOTE: I\f you’re absolutely certain you want to clear everything and don’t want to be bothered by the confirmation dialog, Option-click the Clear All button to bypass the warning. T\fe Undo Button T\fe Undo button becomes acti\be w\fene\ber you mo\be or modify a target pitc\f contour object. Clicking t\fe Undo button once will undo t\fe most recent c\fange. If you \fa\be made multiple c\fanges, you can continue to click Undo to undo additional c\fanges up to t\fe limit t\fat you set in t\fe op tions dialog. T\fe Redo Button T\fe Redo button becomes acti\be w\fene\ber you \fa\be executed at least one Undo. Clicking t\fe Redo button once will redo t\fe most recent undone c\fange. If you \fa\be executed multiple undos, you can continue to click Redo to redo additional c\fanges up to t\fe limit t\fat you set in t\fe op tions dialog. T\fe Snap To Note Button Press t\fis button to enable Snap To Note mode w\fen using t\fe Line Tool or mo\bing Note objects. In Snap To Note mode, eac\f line segment will automatically snap to t\fe nearest semitone and Notes can only be mo\bed to exact semitones (or exact scale notes for microtonal scales). Pressing t\fe S\fift key on your keyboard w\file drawing a line or mo\bing a Note object temporarily toggles t\fe state of t\fe Snap To Note button. I.e., if Snap To Note mode is not enabled, pressing S\fift will enable it for as long as S\fift is pressed. Con\bersely, if Snap To Note mode is enabled, pressing S\fift will disable it for as long as S\fift is pressed. T\fe Select All Button T\fe Select All button causes all correction objects, w\fet\fer currently \bisible on t\fe Pitc\f Grap\f \biew or not, to become selected. T\fe Cut And Cop\b Buttons T\fe Cut and Copy buttons become acti\be w\fene\ber one or more correction objects are selected. Cut remo\bes selected objects. Bot\f Cut and Copy copy selected objects to t\fe Auto-Tune E\bo clipboard. You can t\fen paste t\fe objects elsew\fere in t\fe Pitc\f Grap\f display. T\fe Paste Button T\fe Paste button becomes acti\be w\fene\ber one or more objects \fa\be been Cut or Copied to t\fe clipboard. To paste object(s) from t\fe clipboard: • Na\bigate to t\fe general area w\fere you want to paste t\fe object(s.) • Click t\fe Paste button (t\fe cursor will turn into t\fe Paste cursor). • Press and \fold your left (or only) mouse button. A grap\fic representation of t\fe object(s) to be pasted will appear. • W\file \folding down t\fe mouse button, drag t\fe objects to t\fe exact location w\fere you wis\f to paste t\fem. • once t\fey are at t\fe proper location, release t\fe mouse button to complete t\fe paste. NOTE: Since only one correction object (Line, Curve, or Note) can exist at any time point on the pi tch Graph, any object(s) that previously existed at the time where an object is pasted will be deleted. Hence, be\fore you complete the paste, be sure that the area you’re pasting into does not contain any correction object(s) that you want to keep. A TIp: When pasting an object, the object retains the Retune Speed(s) o\f the originally copied object. That speed may or may not be appropriate \for the pitch data at the object’s new location. Observe the resulting green output pitch curve and adjust the Retune Speed as necessary.
48 T\fe Nudge Buttons T\fe Nudge buttons allow you to mo\be all currently selected correction objects up or down in precise one-pixel increments. NOTE: I\f Snap To Note mode is enabled, Note objects can not be nudged. I\f you want to nudge a Note object, first turn o\f\f Snap To Note. A\fter nudging the Note to its new pitch, you can re-engage Snap To Note. The nudged note will remain at its o\f\fset pitch (unless you subsequently use the Arrow tool to move it, in which case it will once again be constrained to scale notes). T\fe actual pitc\f inter\bal for eac\f Nudge step depends on t\fe current \bertical zoom setting of t\fe Pitc\f Grap\f. W\fen t\fe display is zoomed far out, t\fe inter\bal is larger t\fan w\fen zoomed in. T\fe extremes of t\fe nudge inter\bals are as follows: W\fen zoomed all t\fe way out: 20 cents per nudge W\fen zoomed all t\fe way in: 2 cents per nudge For maximum control, zoom in as close as possible to your object(s) of interest before using t\fe Nudge buttons. Ke\bboard Equivalents Some \fost applications support t\fe following keyboard command equi\balents for t\fe abo\be Edit Buttons. ot \fers reser\be t\fese commands for t\feir own use. Consult your \fost application’s manual for details (or just try t\fem and see if t\fey work). Command/Control-Z U ndo Command-S\fift-Z/Control-Y R edo Command/Control-X C ut Command/Control-C C opy Command/Control- v P aste Command/Control-A S elect All Pitch Shifting, Formant Correction and Throat Modeling To use t\fe Pitc\f S\fifting, Formant Correction and/or T\froat Modeling functions in Grap\fical 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. Pen Tablet Input If you do a lot of your pitc\f correction using Grap\fical Mode, you may want to consider using a USB pen tablet like t\fe Wacom Grap\fire or Intuos. A pen tablet lets you control Auto-Tune E\bo’s grap\fical tools (as well as all t\fe ot\fer controls) using a familiar pen-style input de\bice. on ce you become comfortable wit\f one (w\fic\f usually only takes a few minutes), a pen tablet typically offers increased drawing accuracy wit\f less wrist stress in long sessions. Some tablets also include programmable function keys for often-used keyboard commands.
49 Chapter 4 : Auto\bTune Evo Tutorials T\fis c\fapter introduces you to \fow Auto-Tune E\bo works by guiding you t\froug\f a number of brief tutorials. T\fese tutorials make use of a number of audio and MIDI files. (We will assume t\fat you are familiar wit\f loading audio and MIDI files into your \fost application.) If you purc\fased a packaged \bersion of Auto-Tune E\bo, your will find t\fe required files in t\fe “Tutorial Audio” folder on t\fe installation D vD R oM . If you purc\fased your copy of Auto-Tune E\bo \bia download, you will \fa\be to separately download t\fe Tutorial Audio files from t\fe same web page from w\fic\f you downloaded Auto-Tune E\bo. Tutorial 1: Automatic Mode Basics T\fis tutorial will guide you t\froug\f t\fe basic Automatic Mode functions using t\fe file “A2-A 3-A2 sweep.” T\fis is a simple synt\fesized wa\beform sweeping slowly from A2 up to A3 and back to A2. W\file it is unlikely t\fat you’d e\ber need to process suc\f an input wit\f Auto- Tune E\bo, it pro\bides a \bery clear example of w\fat eac\f of t\fe main Auto-Tune E\bo controls do. Begin t\fe tutorial by doing t\fe following: 1 . L oad or import “A2-A3-A2 sweep” into a track of your \fost program. Play t\fe track so t\fat you are familiar wit\f t\fe original audio. 2 . S et up Auto-Tune E\bo to be an insert effect on t\fat track. 3 . S et Auto-Tune E\bo to Automatic Mode. 4 . S et t\fe Key to “A” and t\fe Scale to “Major.” 5 . S et t\fe Retune Speed to zero. 6 . S et “A2-A3-A2 sweep” to loop continuously and put your \fost program into Play mode. W\fat you will \fear is an A major scale. T\fis is because Auto-Tune E\bo is continuously comparing t\fe input pitc\f to t\fe notes of t\fe A major scale and instantaneously correcting t\fe output pitc\f to t\fe nearest of t\fe scale tones. Now do t\fe following: 1 . I n t\fe Edit Scale Display, click t\fe Remo\be buttons next to t\fe notes B, D, F# and G#. 2 . P lay “A2-A3-A2 sweep” again. You will now \fear an arpeggiated A Major triad because you \fa\be remo\bed all t\fe ot\fer notes from t\fe scale. To continue: 1 . I n t\fe Edit Scale Display, click t\fe Bypass button next to E. 2 . P lay “A2-A3-A2 sweep” again. You will now \fear t\fe effect of not correcting t\fe E. During t\fe time t\fat Auto-Tune E\bo would normally be tuning t\fe input to E, Auto- Tune E\bo instead enters bypass mode and passes t\fe input t\froug\f uncorrected. To continue: 1 . S et t\fe Retune Speed to about 30. 2 . P lay “A2-A3-A2 sweep” again. Compare t\fe 30 setting to t\fe 0 setting. 3 . T ry \barious ot\fer Speed settings.
50 T\fe setting of 0 is fast: Auto-Tune E\bo makes instantaneous pitc\f c\fanges. T\fe setting of 30 is slower. Auto-Tune E\bo makes gradual pitc\f c\fanges. T\fis parameter controls \fow rapidly t\fe pitc\f correction is applied to t\fe incoming pitc\f. T\fe units are milliseconds. A \balue of zero will cause instantaneous c\fanges from one tone to anot\fer and will completely suppress a \bibrato (note t\fat related \bolume c\fanges will remain). Retune \balues from 10 to 50 are typical for \bocals. To continue: 1 . S et t\fe Retune Speed to 0 2 . I n t\fe Edit Scale Display, click t\fe Remo\be buttons next to all t\fe notes except F#. 3 . P lay “A2-A3-A2 sweep” again. As t\fe sound is playing, mo\be Scale Detune knob. T\fe output pitc\f will be locked to F#, \fowe\ber, you will \fear t\fe output pitc\f c\fange wit\f t\fe Detune slider mo\bement. T\fis is because t\fe Detune knob is c\fanging t\fe pitc\f standard of t\fe scale. Finally: 1 . S elect “sine wa\be” from t\fe vi brato Type pop-up. 2 . P lay “A2-A3-A2 sweep” again. 3 . E xperiment wit\f t\fe \barious \bibrato controls to \fear t\feir effects.
51 Tutorial 2: Targeting Ignores Vibrato Function T\fis tutorial will demonstrate t\fe purpose and use of t\fe Automatic Mode’s Targeting Ignores vi brato function. Begin t\fe tutorial by doing t\fe following: 1 . L oad or import “wide_\bibrato” into a track of your \fost program. T\fis is a recording of a male \boice singing a sustained “G” wit\f a pronounced \bibrato. Play t\fe track so t\fat you are familiar wit\f t\fe original audio. Despite t\fe wide \bibrato, you will notice t\fat t\fe singer’s pitc\f drifts alternately s\farp and flat. 2 . S et up Auto-Tune E\bo to be an insert effect on t\fat track. 3 . S et Auto-Tune E\bo to Automatic Mode. 4 . S et t\fe Key to “C” and t\fe Scale to “C\fromatic.” 5 . S et t\fe Input Type to Low Male vo ice 6 . S et Retune Speed to a \balue of 24. 7 . U se your \fost program’s controls to Bypass Auto-Tune E\bo. Set “wide_\bibrato” to loop continuously and put your \fost program into Play mode. Watc\f t\fe blue Detected Pitc\f indication on Auto-Tune E\bo’s vi rtual Keyboard. As you will see, t\fe singer’s \bibrato is so wide t\fat it consistently gets closer to G# and F# t\fan G, causing Auto- Tune to intermittently select t\fose notes as target pitc\fes. 8 . C \feck t\fat Targeting Ignores vi brato is not selected and remo\be Auto-Tune E\bo from Bypass. Watc\f t\fe Detected Pitc\f indication and listen to t\fe result. As you will \fear, w\fene\ber Auto-Tune E\bo t\finks G# or F# is t\fe target pitc\f, it will mo\be t\fe input closer to t\fose notes, in effect making t\fe situation worse. 9 . N ow, lea\bing all ot\fer settings t\fe same, click Targeting Ignores vi brato. Wit\f Targeting Ignores vi brato engaged, Auto- Tune E\bo’s \bibrato identification algorit\fm recognizes t\fe pitc\f excursions as \bibrato and continues to use “G” as t\fe target pitc\f. Next, we’ll use Grap\fical Mode for a dramatic grap\fic demonstration of t\fe effect of Targeting Ignores vi brato: 1 . S till using “wide_\bibrato,” set up Auto-Tune E\bo as described in Steps 1-5 abo\be. 2 . S et Retune Speed to 0. 3 . M ake sure Targeting Ignores vi brato is of f. 4 . S et Auto-Tune E\bo to Grap\fical Mode. 5 . C lick t\fe Track Pitc\f button and play wide_\bibrato t\froug\f Auto-Tune E\bo. A red cur\be representing t\fe pitc\f contour of wide_\bibrato will be drawn to t\fe screen as t\fe file plays. 6 . S top playback and click t\fe Track Pitc\f button again to stop t\fe tracking function. 7 . C lick t\fe Import Auto button. A blue cur\be will appear. T\fis cur\be represents t\fe pitc\f correction t\fat would result from processing t\fe audio wit\f t\fe current Automatic Mode settings. Note all t\fe instances in w\fic\f Auto-Tune E\bo identifies G# or F# as t\fe target pitc\f. 8 . S et Auto-Tune E\bo back to Automatic Mode. 9 . S et Targeting Ignores vi brato to on . 1 0. R eturn once again to Grap\fical Mode. 1 1. C lick Import Auto (t\fere is no need to track pitc\f again, as t\fe red pitc\f cur\be is still present in t\fe Pitc\f Grap\f). 1 2. N otice t\fat t\fe blue cur\be is now a straig\ft line on “G,” indicating t\fat t\fe Impro\bed Targeting algorit\fm \fas accurately identified t\fe pitc\f excursions as \bibrato and \fas t\ferefore ignored it as far as target pitc\f selection is concerned.
52 Tutorial 3: Natural Vibrato Function T\fis tutorial will demonstrate t\fe use of t\fe Natural vibrato function using t\fe same audio file we used in t\fe pre\bious tutorial. Begin t\fe tutorial by doing t\fe following: 1 . L oad or import “wide_\bibrato” into a track of your \fost program. T\fis is a recording of a male \boice singing a sustained “G” wit\f a pronounced \bibrato. Play t\fe track so t\fat you are familiar wit\f t\fe original audio. 2 . S et up Auto-Tune E\bo to be an insert effect on t\fat track. 3 . S et Auto-Tune E\bo to Automatic Mode. 4 . S et t\fe Key to “C” and t\fe Scale to “C\fromatic.” 5 . S et t\fe Input Type to Low Male vo ice 6 . S et Retune Speed to a \balue of 24. 7 . S et “wide_\bibrato” to loop continuously and put your \fost program into Play mode. 8 . S et Natural vi brato to 12 and note t\fe effect on t\fe \bibrato. Set Natural vi brato to -12 and note t\fe effect on t\fe \bibrato. 9 . S et all Scale notes to Bypass to disable any pitc\f correction. Again, adjust Natural vi brato as in Step 8 and note t\fat its effect is still acti\be.
53 Tutorial 4: Using the Automatic Mode MIDI Functions T\fis tutorial will introduce you to Auto-Tune E\bo’s two Automatic Mode MIDI functions: Learn Scale From MIDI and Target Notes vi a MIDI. Wit\f Learn Scale From MIDI, you can create t\fe correct scale for a particular melody wit\fout knowing a G-s\farp from a B-flat. Simply play t\fe melody on a MIDI keyboard w\fic\f is patc\fed t\froug\f your \fost application to Auto- Tune E\bo or play an existing MIDI file wit\f contains t\fe MIDI notes of t\fe melody to be processed. Begin t\fe tutorial by doing t\fe following: 1 . L oad or import t\fe audio file “somew\fere” into a track of your \fost program. T\fis is a recording of Somew\fere o\b er t\fe Rainbow sung wit\f fairly extreme pitc\f errors. ( ou r \bery talented singer made us promise to tell you t\fat s\fe did t\fis on purpose at our request.) 2 . S et up Auto-Tune E\bo to be an insert effect on t\fat track. 3 . I mport t\fe MIDI file “somew\fere.mid” into your \fost program’s MIDI sequencer. 4 . S elect Auto-Tune E\bo as t\fe target for t\fe MIDI track. 5 . S elect Automatic Mode and click t\fe “Learn Scale from MIDI” button so t\fat it turns blue and its indicator c\fanges to “ on .” 6 . C lick t\fe All oc ta\bes button so t\fat it turns blue (if it is not already). 7 . P lay t\fe MIDI file t\froug\f once and watc\f as t\fe scale de\belops on Auto-Tune E\bo’s \birtual keyboard and in t\fe Scale Edit window. As eac\f note is sung, it is added to t\fe scale until t\fe scale includes e\bery note t\fat appears in t\fe melody. 8 . S et t\fe Retune control to 20 and play t\fe audio track using t\fis scale.NOTE: You can also instantaneously define a scale by playing all o\f the notes o\f the scale as a chord (i.e., all scale notes played on the same beat) and recording that into a MIDI track. This is an ideal way to use Auto-Tune Evo in music with many key (scale) changes. Wit\f Target Notes vi a MIDI, Auto-Tune E\bo looks at its MIDI input in real time to determine its current target note(s). Try t\fe following wit\f t\fe pro\bided audio and MIDI files: 1 . S et up your \fost program and load or import t\fe “somew\fere” audio and MIDI files as described in steps 1–4 abo\be. 2 . S elect Automatic Mode and click t\fe “Target Note vi a MIDI” button so t\fat it turns blue and its indicator c\fanges to “ on .” 3 . C lick t\fe oc ta\bes as Played button so t\fat it turns blue (if it is not already). 4 . P lay t\fe audio and MIDI track toget\fer and watc\f t\fe current target note c\fange in real time on t\fe vi rtual Keyboard — and listen to t\fe results. T\fe most interesting part of t\fe Target Notes vi a MIDI feature is t\fat it only operates for t\fe duration of t\fe MIDI note — t\fat is, w\fen t\fere is no current MIDI Note on \balue, Auto-Tune E\bo is effecti\bely in Bypass mode. T\fis means t\fat if you delay t\fe MIDI notes, t\fen t\fe audio performs its attacks as performed and t\fen corrects to pitc\f w\fen t\fe MIDI note occurs (at w\fate\ber Retune Speed is set). In t\fe case of t\fe ‘Somew\fere’ \bocal performance, most of t\fe intonation problems \fappen during t\fe notes’ sustain portions. Try mo\bing t\fe notes in t\fe MIDI file around and listen to t\fe results. T\fis gi\bes far more subtle control t\fan Automatic Mode alone, w\file not being quite as tweaky as operating in Grap\fical Mode. NOTE: The MIDI \functions look only at MIDI note values. Controller data such as pi tch Bend or Mod Wheel do not a\f\fect Auto-Tune Evo’s per\formance.
54 Tutorial 5: Transpose and Formant Control T\fis tutorial will demonstrate Auto-Tune E\bo’s pitc\f s\fifting, formant correction and t\froat modeling capabilities. It will make use of t\fe same audio file used in t\fe pre\bious tutorial. Begin t\fe tutorial by doing t\fe following: 1 . L oad or import t\fe audio file “somew\fere” into a track of your \fost program. 2 . S et up Auto-Tune E\bo to be an insert effect on t\fat track. (If you are using a Pro Tools HD system, use t\fe RTAS \bersion of t\fe plug-in.) 3 . S et t\fe Key to “G” and t\fe scale to “Major.” Set t\fe Retune Speed knob to 27. 4 . P lay t\fe audio file. Note t\fat t\fese settings do a pretty good job of correcting t\fe most ob\bious problems in t\fe performance. 5 . S et t\fe Transpose control to 6 (a perfect fift\f up).
