GridSync
BPM Drift, Fixed. Instantly.
The mise en place for hybrid production — AI-generated stems, calibrated and grid-locked, ready the moment you open your DAW.
Mise en Place for the Modern Producer
Stems calibrated.The music is yours.
Think of it like a professional kitchen. AI is your prep cook — fast, capable, endlessly resourceful. But what AI generates isn't music. It's raw material. And raw material needs calibration before the chef can work. BPM drift is the imperfection GridSync corrects — measuring each stem's actual tempo, converting every file to your exact project BPM, delivering ingredients that are trimmed, tuned, and ready. What you do with them is entirely yours to create.
The BPM Drift Problem
The Hybrid Production Problem
Suno says 128 BPM.Your DAW disagrees.
When AI-generated stems arrive in your DAW, they carry creative potential — and an invisible flaw. BPM drift: the actual audio rarely sits exactly on the declared tempo. 127.3, 127.8, 128.2. Imperceptible on its own. The moment you place a stem on a grid in Logic Pro or Ableton, the kitchen falls apart.
GridSync performs the calibration your session demands. IBI analysis measures each stem's actual tempo with sub-millisecond precision; pitch-preserving time-stretch converts every file to your exact project BPM. Trimmed, tuned, grid-locked — mise en place complete. Now you produce.
What It Does
Every Tool Your Kitchen Needs.
IBI Precision Analysis
Inter-Beat Interval detection measures the actual tempo of each stem with sub-millisecond accuracy — not the declared BPM, but the one the material is truly living at.
Batch Stem Calibration
Drop a folder of stems — drums, bass, melody, vocals, 2mix — and calibrate them all to your project BPM in a single click.
Pitch-Preserving Stretch
Time-stretching that keeps your material sounding natural. No artifacts, no coloration — just calibrated stems that still sound exactly like the originals.
Drift Visualization
See the imperfection before and after calibration. A clear before/after beat grid view shows exactly what was corrected — stem by stem, beat by beat.
Any Project BPM
120, 128, 140, 174 — calibrate to any tempo your session demands, regardless of what the source material originally carried.
One Drop. Done.
Drop the stems, set the BPM, click convert. GridSync handles the mise en place. You handle the music.
How It Works
Drop. Calibrate. Produce.
Mise en place in seconds.
Drop Your Stems
Drag and drop your AI-generated stem folder into GridSync. WAV, AIFF, MP3 — any format accepted.
Set Project BPM
Enter your DAW project BPM. GridSync measures each stem's actual tempo using IBI precision analysis.
Calibrated & Ready
Grid-locked stems exported to a new folder — pitch-preserved, tempo-matched, ready to drop straight into Logic, Ableton, or any DAW.
Who It's For
Built for thehybrid producer.
You lead the session. AI sources the material; GridSync calibrates it. Your brigade handles the mise en place so you can focus entirely on the music.
EDM / Trance / Techno
The Club Producer
You source AI stems as raw material and build the full track your way in Ableton. GridSync calibrates every file to your project BPM — mise en place handled, session uninterrupted.
Hip-Hop / Lo-Fi / Trap
The Beat Maker
You pull AI-generated loops and shape them into original music in Logic Pro. GridSync tunes each stem to your tempo so the creative process — import, chop, layer, arrange — flows without friction.
Sync / Film / Commercial
The Sync Composer
AI supplies the texture; you place every element against picture. GridSync calibrates your stems to frame-accurate tempo — precision mise en place for deadline-driven production.
