Qie Stem Slicer FAQ

Stem separation (also called stem splitting) is the process of using AI to isolate individual instruments from a mixed song. Qie Stem Slicer uses advanced AI neural networks to analyze audio and separate it into individual stems — vocals, bass, melody, drums, and individual drum components like kick, snare, hi-hat, cymbal, ride, and tom.

Drag any song from your music library into Qie and set a starting point — the time in the song where you want loops to begin. Qie separates the track into 10 stems (bass, melody, vocal, full drums, kick, snare, hi-hat, cymbal, ride, tom) and slices it into production-ready 8-bar loops from your starting point, each labeled by BPM, key (Western & Camelot), bar number, and energy density. You can then export everything as audio, MIDI, or an Ableton Live session.

Qie separates songs into 10 full stems — more than any other stem splitter on the market. You get: Bass, Melody, Vocal, Full Drums, Kick, Snare, Hi-Hat, Cymbal, Ride, and Tom. Most competitors only offer 4-6 stems. Qie's 6-component drum separation (kick, snare, hi-hat, cymbal, ride, tom) is a unique feature that gives producers and DJs granular control over every drum element.

Yes — Qie is the only stem splitter that automatically generates Ableton Live Session View projects (.als files). You get two projects per song: one with audio tracks and one with MIDI tracks. Each project has color-coded tracks, Complex Pro warping, and Follow Actions enabled. Just open the .als file in Ableton 12+ and start producing immediately.

Yes. Qie auto-generates Ableton Live Session View projects (.als) from any song — 10 color-coded stem tracks with your 8-bar loops placed as launchable clips, Complex Pro warping, Follow Actions, and key/BPM metadata baked in. You get separate audio and MIDI projects. Open the .als in Ableton 12+ and start arranging, remixing, or performing immediately, no manual track setup required.

Yes. If you use rekordbox, Qie reads your rekordbox library to pull each track's BPM, key, and Hot Cue A — using Hot Cue A as the B1 downbeat so your 8-bar loops line up with the analysis you already trust. Every stem and loop is labeled with BPM and Camelot key for harmonic mixing, and exported as standard 44.1kHz WAV you can load into your DJ or production setup.

Qie automatically chops every stem into perfect 8-bar loops synced to the detected BPM. Each loop is labeled with BPM, musical key (Western and Camelot notation), bar number, and energy density level. This lets producers build organized loop libraries from any song and quickly find the right loop for their productions. No other stem separator offers automatic loop creation.

Qie offers a free trial that lets you process 5 songs with full functionality. The full version is a one-time purchase of $69 USD — no subscription, no monthly fees. Once activated, you get unlimited offline processing forever, plus lifetime updates via email.

Qie offers more stems (10 vs 4-6), unique features like 8-bar loop auto-chopping and Ableton project generation, and costs $69 one-time vs recurring subscriptions ($99+/year). Qie also processes locally on your computer for faster results and complete privacy — no uploading to the cloud. Visit the Compare page for a detailed feature-by-feature breakdown.

Yes. Qie generates MIDI files for every stem using Spotify's basic-pitch neural network for melodic instruments (bass, melody, vocals) and librosa onset detection for drums. Each drum component maps to standard General MIDI notes. You also get full Ableton MIDI projects with all transcriptions embedded and ready to edit.

The free trial requires an internet connection for each session. Once you purchase the full version and activate your license key, Qie works completely offline — no internet required. All AI processing happens locally on your Mac or Windows PC using your own hardware.

Simply drag any song (WAV, MP3, FLAC, AIFF, M4A, AAC, or OGG) into Qie and click Process Audio. Qie's AI will separate the full drum track, then further isolate individual drum components: kick, snare, hi-hat (with open/closed classification), cymbal, ride, and tom. Each component is exported as a separate WAV file and organized into 8-bar loops.

Qie accepts WAV, MP3, FLAC, AIFF/AIF, M4A, AAC, and OGG as input formats. All stems and loops are exported as high-quality 44.1kHz WAV files. MIDI files are also generated for every stem. Qie runs on macOS 14.0+ (Apple Silicon) and Windows 10/11 (64-bit).
