Key Shift Pro · By Soniteq

Waitlist

Key Shift Pro generates all your key variants in minutes, not hours.

Key Shift Pro is batch key-transposition software for professional music creators. It generates multi-key audio deliverables from a single source file — eliminating the manual pitch-shift, rename, and export cycle that burns hours on sync and library work.

Batch utility for sync, sound design, and delivery workflows where manual pitch-shifting burns production time. 12 keys in the time it takes to bounce one.

In Short

Key Shift Pro takes one source audio file, generates pitch-shifted versions across every key you need, auto-names each output with the correct key suffix, and packages them delivery-ready — in a single batch operation that replaces 2–4 hours of manual work per sync submission.

Batch Process

One source. Every key. Delivery-ready.

The complete batch pipeline — from a single audio file to a full set of correctly named key variants — in a single operation.

Load source audio

Drop in your source file — stems, mix, or instrument layer. Key Shift Pro reads the file and prepares it for the batch engine.

WAV / AIFF Stems or full mix

Select target keys

Choose any combination of the 12 chromatic keys. Common sync presets (all 12, major-only, relative pairs) are one click — or define your own set.

Batch shift runs

Key Shift Pro processes every variant in a single batch pass — high-quality pitch shifting without degradation artifacts that make sync supervisors reject tracks.

Quality-preserving Parallel processing

Auto-named and export-ready

Every output file gets the correct key suffix automatically. The full set is packaged delivery-ready — or piped directly into Export Flow for metadata embedding and preflight.

Why It Exists

Every sync submission set requiring multiple keys is 2–4 hours of manual bounce-rename-export work per track. Key Shift Pro compresses that into a single operation — so you can respond to more briefs, faster, without sacrificing delivery quality.

Core Capabilities

What Key Shift Pro does at every step.

Four capabilities that eliminate the manual pitch-shift-rename-export cycle from your sync and delivery workflow.

Multi-key batch generation

Select your source file, choose which keys you need, and Key Shift Pro generates the complete set — all 12 keys if needed — in a single operation.

Auto-naming with key suffix

Output files are automatically tagged with their key (e.g., TrackName_Bb.wav) — no manual renaming step before sending to a sync library.

Format selection per output

Choose WAV, MP3, or both per key set per batch. Libraries and clients have different format requirements — Key Shift Pro handles both in one pass.

Direct integration with Export Flow

Generated key variants feed straight into Export Flow's delivery preflight — naming, metadata, and version validation before the full package goes out.

Who Key Shift Pro is built for

Sync Writer

Responding to multiple briefs requiring key-specific versions

When a brief asks for A, B♭, C, and D versions of the same track, Key Shift Pro removes the manual repetition. More submissions, less production overhead.

Sound Designer

Building multi-key libraries for catalog delivery

Sound design libraries require complete key coverage for flexibility. Key Shift Pro generates the full catalog in batch — not file by file over an entire afternoon.

Film Composer

Generating alternate key versions for placement flexibility

Music supervisors sometimes need an alternate key to fit a scene. Key Shift Pro has it ready before they ask — without a last-minute session in your DAW.

Use Cases

Standalone or full stack.

Standalone: sync and library work

Use Key Shift Pro on its own for any workflow where multi-key variant generation is the bottleneck. Select source, choose keys, export — done.

Sync brief responses across multiple keys
Sound design library catalog generation
Client-requested alternate pitch versions

Full stack: Kora + Export Flow

When used with the complete Soniteq stack, Key Shift Pro slots into the delivery arc — variants generated, then delivered through Export Flow with naming and metadata validated.

Common Concerns

Questions before you start.

"How does the pitch quality compare to manual transposition in my DAW?"

Key Shift Pro uses professional-grade pitch algorithms tuned for music audio — comparable to dedicated pitch-shifting plugins. For most sync and library submissions, the quality difference from manual DAW processing is inaudible.

"Can it process multiple source files at once?"

Yes. Batch mode lets you queue multiple source files and run the full key set across all of them in one operation. Especially useful for catalog delivery with consistent naming across dozens of tracks.

"Do I need Export Flow too, or does Key Shift Pro handle delivery naming on its own?"

Key Shift Pro handles key-suffix naming automatically. For full delivery validation — metadata embedding, version confirmation, client-specific naming rules — pair it with Export Flow. Both work independently or together.
