Cableguys added PitchShaper to its ShaperBox 3 line in October 2025. It is the company's take on pitchshifting, rebuilt around the drawable LFO workflow that made ShaperBox a studio staple. Instead of setting a fixed number of semitones, you draw how pitch and formant move over time, sync that motion to your song, and trigger it with MIDI or audio. It costs $39, and with ShaperBox on sale this season, it earns a full review.
At a glance: a drawable pitchshifter that runs inside ShaperBox 3, with four algorithms (Complex, Vocals, Drums, Vintage), independent drawable LFOs for pitch and formant, up to three-band processing, and envelope followers for audio-reactive shifting. It runs on Windows 7 and up and macOS 10.15+ (Intel and Apple Silicon) as VST2, VST3, AU and AAX. It is $39 / €39, has a free trial, and comes free for recent ShaperBox 3 Bundle owners.
What is PitchShaper?
PitchShaper is a pitchshifter, but it is built like an effect for sound design rather than a correction tool. A classic pitchshifter transposes audio by a set interval. PitchShaper lets you draw a curve that defines how the pitch moves through time. A held vocal can bend up an octave, a drum loop can glitch across stepped intervals, and a pad can drift into a riser, all locked to the grid.
It lives inside Cableguys ShaperBox 3, the multi-effect that hosts the whole Shaper family. PitchShaper can run on its own or stack with up to ten other Shapers, so a pitch move can sit in the same chain as filtering, gating and saturation, each driven by its own drawable modulation. If you want transparent tuning instead, Soundtoys Little AlterBoy and Antares Auto-Tune sit at the correction end of the spectrum, where PitchShaper deliberately does not.
What's new in PitchShaper
Four algorithms for four jobs
PitchShaper ships with four shifting algorithms, each tuned for a different source. Complex handles anything, from a single instrument to a full polyphonic mix, with tight, time-aligned transients that avoid the glitched attacks many pitchshifters produce. Vocals smoothly shifts single voices and monophonic instruments, and it unlocks full formant control. Drums preserves transient punch and fundamental tone, so beats stay crisp while you bend them. Vintage brings lo-fi granular grit for retro jungle breaks, robotic vocals and sparkling ear candy. Four purpose-built engines in one plugin let you pick the right trade-off per track, rather than fighting a single generic algorithm.
Drawable pitch and formant LFOs
This is the ShaperBox DNA. Pitch offset and formant shift each get their own drawable LFO, so you animate them with curves, steps and ramps drawn in seconds. Sync them to the song, trigger them with MIDI notes, or fire them from audio transients. Stamping a melody, a slide or a formant pattern onto a sound becomes a quick visual gesture. Because it is an LFO, it repeats in perfect time instead of needing automation drawn by hand.
Deep formant control
The Vocals and Drums modes include a Formant control with its own drawable LFO, envelope follower and a Density parameter for smoother results. You can make a voice deeper, thinner, younger or older, push it from natural to robotic, or shift its perceived character. On percussion the same control becomes a timbre-shaping tool, from tasteful tucks to broken textures. Separating formant from pitch is what lets PitchShaper transpose without the chipmunk effect, or lean into it on purpose.
Multiband shifting
PitchShaper can split pitch shifting across up to three frequency bands. Repitch only the bass in a full loop, tune low-end drum punch independently of the treble snap, or shift just the tops to add hi-fi texture. Combine all three bands for custom harmonies and advanced sound design. Multiband turns a single pitch move into a surgical or wildly creative tool, depending on how you set the crossovers.
Envelope followers and synth-like glide
An envelope follower makes pitch and formant react to the dynamics of the incoming sound in real time. You get self-varying hi-hats, warbling tape-style instability or vocal formants that twist with every word. A Smooth control turns stepped patterns into synth-like glides, so a sequence of discrete pitches flows note to note like a portamento line. These are the touches that move PitchShaper from an effect you set to one that performs with the material.

PitchShaper vs Soundtoys Little AlterBoy
The closest named competitor for creative pitch and formant work is Soundtoys Little AlterBoy. Both move pitch and formant, but they come at it from different directions.
| Cableguys PitchShaper | Soundtoys Little AlterBoy | |
|---|---|---|
| Core idea | Drawable, rhythmic pitch and formant | Quick pitch, formant and robotic effects |
| Modulation | Drawable LFOs, MIDI and audio triggers | Pitch and formant knobs, MIDI control |
| Multiband | Yes, up to three bands | No |
| Algorithms | Four, source-specific | One character engine |
| Host needed | ShaperBox 3 | Standalone plugin |
| Price | $39 | $99 |
Choose Little AlterBoy for fast, characterful vocal effects and its instantly recognizable hard-tune and robot sounds in a standalone plugin. Choose PitchShaper when you want pitch and formant to move in time, split across bands, and sit inside a modulation chain with other effects. For context on the host itself, our ShaperBox 3 overview covers the full Shaper family.
Who PitchShaper is for
PitchShaper is for producers who treat pitch as a creative effect. Electronic, bass, pop and hip-hop producers who already draw modulation in ShaperBox will feel at home immediately, and the four algorithms make it just as useful on drums and full loops as on vocals. Sound designers who want risers, formant sweeps, tape stops and glitched drums on demand get a deep toolkit for $39.
Skip it if your need is transparent correction or classic note-by-note tuning. That is the job of Auto-Tune, Melodyne or Little AlterBoy's hard-tune, and PitchShaper is built for motion and character instead. It also requires the ShaperBox 3 host, so it makes most sense if you own or plan to own ShaperBox.
How much does PitchShaper cost?
PitchShaper is $39 / €39 as a one-time purchase, for Windows and Mac in VST 2, VST 3, AU and AAX formats. A free trial is available. If you already own the ShaperBox 3 Bundle and bought or upgraded on or after 1 September 2025, PitchShaper is free in your Cableguys account. The full ShaperBox 3 Bundle, which includes PitchShaper and ten other Shapers, sells for around $89 to $99 and is the better value if you want the whole collection.

FAQ
Is PitchShaper worth it?
For creative pitch and formant work, yes. Four source-specific algorithms, drawable pitch and formant LFOs and multiband shifting give you far more motion and character than a standard pitchshifter, and $39 is a low price for that depth. If you only need transparent tuning, a correction plugin is the better buy.
PitchShaper vs Little AlterBoy: which should I get?
PitchShaper draws rhythmic pitch and formant curves, splits them across three bands and runs inside ShaperBox 3. Little AlterBoy is a standalone plugin for fast, characterful vocal pitch and robot effects. Get PitchShaper for tempo-synced motion and sound design, get Little AlterBoy for quick vocal character.
Do I need ShaperBox to use PitchShaper?
Yes. PitchShaper is a module that runs inside the ShaperBox 3 plugin. You can use it on its own or stack it with up to ten other Shapers in the same window.
What are the system requirements?
PitchShaper runs on Windows 7, 8, 10 or 11 (64-bit) and macOS 10.15 or later with Intel and Apple Silicon support. It is available as VST 2, VST 3, AU and AAX.
Is PitchShaper free for existing ShaperBox owners?
If you bought or upgraded to the ShaperBox 3 Bundle on or after 1 September 2025, PitchShaper appears free in your Cableguys account. Otherwise it is a $39 add-on or part of the full bundle.
