Note for M1 Mac Users: This plugin is not yet compiled to work natively on M1 Macs. We are currently in the process of rewriting it so that it will, but it will take some time. In the meantime, it should work under rosetta on M1 Macs.

Easy to use yielding great results quickly, ProVocative is a micro pitch-shift plug-in that’s light on CPU resources, heavy on sound quality, and features high- and low-pass filters for frequency-specific pitch shifting, along with track widening and independent wet/dry mix controls.

Available Formats






  • Instant thicker tracks
  • Micro Pitch Shifting
  • Easy to use without sacrificing control

Micro pitch-shifting has been around for decades and in that time, regardless of format (i.e. hardware or software) it’s functionality has remained largely the same. While some may invoke the “if it ain’t broke, don’t fix it” mantra, who says you can’t go ahead and make it better? Well, nobody at Boz Digital, which is why ProVocative was created. Quick and easy to dial in, its high- and low-pass filters, width control, and wet/dry knobs let you add thickness or bring out the air in vocals without sounding robotic; subtly or aggressively widen guitars, synth pads, or drums; and mix wet and dry signal to taste. It’s light on the CPU and heavy on sound quality.

ProVocative—Just the Facts:

  • Instant vocal, instrument, and track thickening
  • Frequency-selectable micro pitch-shifting and width control
  • Dual-function wet/dry mix or blend controls
  • Easy to use without sacrificing versatility or control
  • Uncompromising sound quality
  • CPU resource-friendly

ProVocative—Cracking the Code

ProVocative is an inspired new version of the legendary micro pitch-shifter of days gone by (A hint to its identity lies within a joke we’ve heard at least, Hmm, 3000 times: Child, you so ugly, Even the tide wouldn’t take you out). While the hardware became ubiquitous in high-end and mid-level studios the world over, it was quite complicated to use. As a result, two go-to presets emerged; 231, which became to go-to for vocal thickening, and 521, which combined micro pitch-shifting with slap delay, the standard for depth and widening. All but the most adventurous tweakers kept that ‘big bucks box’ dedicated to those effects (because who has time to read manuals and futz around while the clock is ticking). In the studio, you want great results and you need them quickly, which is what ProVocative is all about.

Mixer Section

With other pitch-shifting plug-ins, the ability to run the effect in parallel with the dry signal for a more controlled, natural sound, ProVocative generously gives you individual Wet and Dry knobs so you can use it as an insert effect and dial in the amount of effect you want in one convenient location. However, if you prefer the functionality of a blend knob, you can engage the Link button, which gangs the Wet and Dry knobs together to act like a wet/dry mix control.

Filter Section

ProVocative’s most unique addition to traditional pitch-shifting is its high- and low-pass filter section, which enables you to select the frequency range it applies micro-shifting to via slider. You can bypass or enable these filters by clicking on the HPF or LPF symbols. These filters will only EQ the wet sound, leaving the dry sound unaffected. The main benefit of the filter section is that it enables to thicken or widen a specific frequency range while retaining an overall more natural sound—unless you want to go full robotic.

Boz Mix Tip: To achieve a sweet and smooth subtle widening, simply filter out a bit of the high and low end of your pitch shifted tracks.


As its name suggests, width controls widening of the pitch-shifted tracks. When set to positive 100%, the pitch-shifted track is panned to the right, while negative 100% pans the track to the left. When set to 0%, both tracks are panned to the center.


The pitch control ranges from 1 to 20 cents. Once set, ProVocative makes two pitch-shifted tracks, one up and one down by the selected amount.


To create depth, this knob controls the delay between dry and pitch-shifted tracks. It ranges from 20ms to 150ms. Note: Some slight modulationis applied to the delay time in addition to the delay time set. This helps to give a more natural sound.

Like all Boz plug-ins, ProVocative comes with its own presets, shareable across formats, computers, and operating systems, along with an A/B bank that lets you compare settings without losing your settings.

A CPU-friendly, frequency-selective micro pitch-shifting plug-in that will make other mixers and producers wonder how you get such great sounds . . . it’s a ProVocative concept.

  1. P A

    Instant gratification!
    It’s not often that a plugin sounds this good right away.
    Tried it on a vocal sample, wider and thicker.
    Seems nice with the Ozone Imager/correlometer too.
    Just a quick test…

  2. Alexphilipp

    This plugin is not only good for vocal, it suits everything what need to be widened. Only thing i would want to have is time shifting started from 0.0 ms but not from 20.0 ms, because it too much for some sounds.

  3. kevinsparks

    The filtering section is a smart feature

  4. eno

    Well, hello, this one adds up well to my tools box beside the SoundToys alternative. I actually like this one a but more for its precise control. A tool coming quite handy for vocals, but not entirely only that.

  5. fridburg

    highly recommend this. For vocal and guitar

  6. IMAWriter

    For ME, ProVocative is the he BEST of the numerous “fattening/thickening/stereo-izing/doubling” software offerings out there. Like ALL BOz software, it’s blood easy to get what you want FAST. The precepts are excellent starting points, and the flexible modifications make it a snap to get exactly what you want. What is most important is that the results SOUND professional, and when parameters are set reasonably, there are ZERO artifacts. Throw this on a lead vocal, acoustic or electric guitar, and magic happens. IMO, a must have for adding heft, space, and interest to your audio quickly and easily.

  7. jonnybutter

    A very easy and fun way to do the thickening trick. So easy you can try it on anything. Filter out some highs or lows. Play around and have fun fun fun. Boz’ plugs are always fun, clean, and super useable. It’s a good deal at the regular price, but a MUST at the intro price. Just do it!

  8. bmcclure

    It’s a bargain! ProVocate truly does add depth and thickening to pretty much any sound I throw at it, but it has worked particularly well on things like vocals and synths. I’m using it in every project currently.

  9. mistermygo

    Useful plugin for thickening all kinds of sources, it’s an old trick but ProVocative makes it super-simple to get good results.

  10. pettrer

    Fantastic on vocals – truly addictive, and I can’t understand how I’ve been able to get by without it. I started a thread for it on KVR and the other users agreed with me on its great UI and smart workflow. Great work!

  11. wychboy71

    I got this plugin because it awakes the Bass GTR. Anti chorus, chorus. Drops a few plugin combinations which help the CPU load. A different way to control the room dynamics or delay if you choose. Great bargain. One of those you didn’t know you needed

  12. rokit

    Easy to understand and use. Can make a dramatic or subtle difference in vocals, your choice. Extremely easy to get that 50s/60s slap-back vocal sound. Easy to dial in a number of varying sounds. I had no idea what I was missing until I tried it. And now, I would not want to be without it.

  13. tbox1980

    It’s that classic widened vocal sound that you get with Microshift but way more control and options. After demoing both ProVocative was the winner, and for $20 it’s a no-brainer.

  14. doug

    Been waiting for a plugin like this for a while now,simple to use ,affordable,sounds great on vocals!This will become a ‘go to’ plug in.Great job Boz,Love it!

  15. jm.dumas

    Classic vocal sound. Does what the other gazillion microshift plugins do but adds a super useful filter stage. Very well thought out!

  16. alankara

    Handy and easy to use tool. The sound quality is very good and you can get good results but keep sounding ‘natural’. The user interface is simple and looks nice.
    The price is also very nice.. Love this Boz Digital’s new creation!

  17. Matthew Tasa

    What a great Plugin this is. It’s super precise, sounds good and works super smooth. I totally love it and will be using on a lot of coming productions and mixes. Thanx boz Digital Labs for making such an awesome plugin and that at such a great price. You guys are great!

  18. T-3

    I really appreciate simplicity and ease of use in the plugins I use (without sacrificing control and options) and ProVocative definitely fills these requirements. It is so effortless to use and the price-quality-ratio is very lucrative.

  19. ailerom

    I’ve had a few plugins of this type over the years and I have a preference for the basic features. The Boz plugins I have used have been rock solid and stable across 2 computers so I use them with confidence. The feature set in ProVocative is exactly what I am after. The HP/LP as an added bonus I would have lived without but was a really useful feature to add. have used on acoustic guitar, piano and vocals so far with great results both for widening and basic doubling duties.

  20. busik

    This plugin saves a lot of my time! Also it has simple interface with no complications, that is fine by me. Used it on guitar. Totally recommend it.

  21. TTobin

    There are lots of widener/doubler plugs out there. This one is nice for the additional controls, especially filtering of effect and mix control. I give it an A for usability. Still needing to experiment more to compare to other options I’ve been using.

  22. Charles Parks

    This is a great product. I play a lot of up-tempo jazz and funk jazz, I used it on my guitar to thicken it up and on vocal accents. it really brought out the sweetness of my hollow body guitar. On vocals, it added that fullness that merged just right with the guitar.

  23. digerbop

    Awesome, no nonsense widener. I use it on vocals to make them thicker. Great on a thin sounding electric guitar. Also good on acoustic guitar to help is feel more alive.

  24. Kyle Sheppard

    Another great usable tool by Boz at an affordable price. Love how it can add just that right amount of “something” that can make vocals really shine. Haven’t tried it on other instruments quite yet but thoroughly impressed with how it lifts vocal tracks.

  25. Peter-David

    As usual with Boz plugins there are some great useable features! The link/unlink option on the wet and dry knobs is a nice touch. There is a lot of flexibility on offer in one plugin!
    This fits in nicely with The Hoser EQ and Manic Compressor on my Vocal chain!

  26. morpheusrouge

    The ProVocative plugin does a lot and it does it in a way that is easy to use and flexible for a lot of situations. Throw it on isolated vocal tracks and the presets will pretty much get you covered, whether you want to thicken the voice, ground it a little, or make it stand out from the backing instruments. That’s not all, though, because the options are flexible enough that you can fine-tune the settings to use it to fair effect with a chorus or a tack featuring a voice mixed with instrumentation. Good with guitars and other instruments, but listen closely and don’t be afraid to adjust it. All that and it’s attractive, well-documented, and has a low impact on my CPU usage.

  27. Bob Lind

    GUI is A+. Easy to understand, simple to manipulate. I find this to be the case with all Boz’s plugs.

    Sound is A. It’s very easy to overcook Vox. Haven’t tried it yet on bass guitar, but will soon .

    Function is B. As a frequent collector of Boz’s stuff, I leapt to purchase on day 1 of the sale ($19 might make me broke eventually, but it wouldn’t be THIS $19!). Tested in my plug Test session (PT 2018.4) and it worked fine on a stereo track. Stuck it on two mono audio tracks in a working session and it crashed twice; sent the crash reports to Box and had a fix in 28 hours, which worked fine in the same session that had crashed. Confident that it was now AOK, I instantiated on a stereo aux in another working session and it was introducing approximately 4 seconds of slapback delay! I just tried the same thing again and it worked as expected. These are the only issues I’ve ever had with Boz’s plugs, excepting the lack of code that allows Manic Compressor to activate Gain Reduction meters in the PT mixer (hint, hint).

  28. redworks

    As per usual with Boz Digital, this is a solid, useful plugin. It works and it works well. What more can you ask for from a plugin.

  29. opusmachina

    Got it and immediately used it on a current project to thicken the vocals.
    Very useful, the vocal tracks got depth an width and work very well in the mix.
    Will work with other instruments, too, i think, got to check it out…
    Plus: with the introduction price it’s a no-brainer to purchase this plugin. Best spent 19$ this year.

  30. swot

    Very cool to thicken sounds(Vocals, Guitar, whatever). The addition of high and low pass filters is an xlnt addition. With the pitch and width controls you can make choirs and lead/background vocals sound very good. Plus the price was a real nice plus!
    Well Done Boz!

  31. credmond

    My favorite plug in yet. So nice to not have to load up three or four plug ins, really helps with workflow!

  32. pdj

    Bought it on a whim…and I really love it! Use it all the time now…it really fattens up vocals…awesome plugin!

  33. bullyproof

    This is a cool plugin. I have a few shift plugins but this one has a nice ui and a clear path to dialing in the sound you would want. It’s a little heavy on the CPU but it can add a nice feel to your vocals and instruments when tempered. It’s very powerful so you have to be careful not to use too much. But there are few limits to the impact of this on your mix…and with the price you can’t beat it.

  34. xor500

    It’s tight.

  35. DanO

    First I would like to say that I have never had a plugin from boz earlier so this was my first one. I bought it on sale because I needed something to enhance my vocal tracks in a way my usual plugins couldn´t do. I was unsure if this plugin would to the trick since it is so cheap. My other vocal enhance plugin cost me $199.. But I figured what the heck its 19 bucks so I got it. I instantly fell in love with it. It adds like a fatness to my vocals only way for me to explain it is “chocolatey” but stil kept the sharpness. It has this crazy cool “reverb” effect that makes the vocals sound scape take more rook but not overpower the other tracks. I cant praise this plug enough. I use it on all my vocals now. I will definitely get more stuff from boz! Best Regards Dan O

  36. Gwprater

    This is an amazing and quick plugin for adding depth and vibe to vocals. Another hit from Boz.

  37. 348Josh

    After only having this plug for a little over a week, it is already my go to for so many aspects of my mix. Great plug and for the price it can’t be beat!

  38. TSkerritt

    Such a simple device to use, but so useful. Want thicken things up a little? looking for a nice chorus-y effect? Want to get creative with some slap-back? With it’s separate wet and dry controls and the lovely filter section, ProVocative has you covered. An incredibly useful plugin that as already made itself at home in my DAW

  39. mike

    This plugin is a perfect example of how a common effect can be updated with additional features that sets it apart from the crowd. Boz Digital has a knack for this and commonly does in an attractive, logical, and no nonsense UI that streamlines your workflow and is nicely efficient on your CPU.

    To begin, the Width, Pitch and Delay knobs give you a lot of tweakability in a very quick and usable way. Next is the Filter Section (my favorite) where, for example, you can hone in on a specific range for the effect or you can activate the high pass filter on the effect and leave the low-end alone so it doesn’t get smeared.

    The Mixer Section is a feature every plugin should have these days. Dial in your effect with the Wet Knob then mix in the dry signal to taste. Or, if you prefer the usual “Mix Knob”, link the Wet/Dry knobs and dial away. Finally, Gain Stage the changes to your signal with the Output knob. Done.

  40. cgbrown

    This is a solid little plugin. Great as an overall thickener. As mentioned above CPU usage is an issue for older machines, but not too big a deal if you freeze tracks.

  41. John Leitch

    Great plugin! Not just for vocals, try it on guitar or overheads. Only problem for me is CPU usage with my older system, crashes occasionally. All in all A+, thanks Boz!

  42. bakedbeans

    Simple to use and does exactly what it is supposed to do. Careful: it is easy to overdo the effect on vocals. Best to bring it up until just audible and then dial it back a tad. DO: experiment on other instruments and be surprised!

  43. alphaz

    I have bught it to check the effects on vocals, but … I tried it on guitar at first and found it is perfect for thickening the sound without any false artifacts – sounds extremly good on heavy distorted ones, but the classic fender glass sounds amazing too.
    Formerly I was working on vocals and guitars with Revoice Pro, but the plugin is much simpler and faster so it is used on almost all guitars now – vocals are still slightly better sounding treated by Revoice Pro.
    For me there is lack a no delay option in ProVocative, but … there is place left for upgrade maybe 😉

  44. Nardus Niemand

    Provocative was one of those plugins that I bought, tried on a mix that I was working on……and kept it there. Excellent stuff. No need for another vocal widener/thickener.

  45. ToddStudio79

    ProVocative has become my “Go To” plug for vocals!
    It’s like the Swiss Army Knife of vocal processing.
    The High and Low Pass filters are perfect for really dialing in that vocal tone, and of course there is the micro pitch shifting…AMAZING!
    The sound of the plug really allows you to set the vocals perfectly in the mix with whatever type of thickening you want to do.
    I absolutely LOVE IT!!!


    If you used to double, pitch-shift and time shift your vocals – now you only need this plugin. But not only on vocals, you can use ProVocative on instruments too just to give it more stereo width and thicken it up a bit. so get this one to save CPU and time while you mix.

  47. bruce.tunkel

    Great sounding plug, that makes it super easy and intuitive to get just the right pitch/time shift effect. The addition of the low/high pass filters is awesome. Great plug!

  48. ahoova

    For those wanting to very quickly and easily capture “that vocal sound” where the vocal becomes more present, with a thickness and depth that brings out the performance…this is the plugin to do it. The ability to adjust the frequency range of the signal being effected makes this plugin the easiest I’ve tried to perform this task. It can be subtle to more extreme and everything in between.

  49. vtijerina

    Extremely fast workflow, everything is there. Getting it to match what is in your head takes no time. Only thing that would have made it better – using the name I submitted.

  50. Plattmoos

    It’s a nice tool that combines some methods to thicken and spread signals which can be vocals but also other instruments like guitars and synths.
    The range filters and the wet/dry mixing make it very usable and easy to apply.
    ProVocative is a little go-to tool in my plugin arsenal.

  51. kingtfinesse

    great plug in I use it to enhance my vocals and overall final mix 2 thumbs up!!!

  52. 7Salvo

    I have to say that before the launch I fell in love with it. I saw the features and what was capable to do and inmediately knew I was going to buy it, and I did.

    I love how easy it is to use and to get results right away. Instead of doubling vocal (which is a good thing), you just put the plugin, tweak here and there and voilà! you have it.

    I like it on the lead vocals but also I will put it in the backing vocals, because it gives a little bit of width and make it sound fuller.

    Great plugin!

  53. azlanah

    highly recommend this. pretty smooth sound, and definitely mono-compatible and doesn’t have any of the unwated flangy or out-of-phase effect when listening in mono. I would like to suggest also a knob to control the formant of the audi. It should be designed independently for the left and right channels. this would me the sound even bigger and wider and more awesome!

  54. hhziegler

    Provocative help me to fit the Vocals perfectly into the mix. It is pretty easy to handle and makes my life easier every day.

  55. ThomC

    Love how reliable and great sounding Boz Digital’s plugins are. I’m currently working on a new album and have already been using ProVocative to enhance the thickness of my vocal choruses.

    ProVocative also shines on acoustic guitars, either as a widening chorus effect or as a plain guitar stereoizer. Thanks the the dedicated Hi-pass/Lo-pass sliders, I can hone in on the set of frequencies that I want to widen to give more width to selected portions of the song.

    ProVocative can also be used as a nice Slapback effect. Increasing the delay value results in a great sounding slapback echo that I’ve already used to give some depth to vocal parts.

    There must be many other applications that I’ve yet to explore! I highly recommend it 🙂
