Qie Stem Slicer FAQ
Frequently Asked Questions
What is stem separation and how does it work?
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.
How does Qie Stem Slicer work?
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. Export WAV loops from the output folder, or turn on Generate MIDI / Generate Ableton Live project in Settings when you want those formats.
How many stems can Qie separate a song into?
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.
Does Qie Stem Slicer work with Ableton Live?
Yes — Qie can build Ableton Live 12 Session View projects (.als files) when Generate Ableton Live project is enabled in Settings. You get up to two projects per song (audio stems and, with Generate MIDI on, a MIDI project). Each uses 10 color-coded tracks with Complex Pro warping and Follow Actions where applicable. Open the .als in Live 12+ and start from organized clips instead of dragging WAVs by hand.
Can Qie turn a full song into an Ableton Live project?
Yes, when Generate Ableton Live project is on in Settings. Qie writes Session View projects with 10 color-coded stem tracks, your 8-bar loops as launchable clips, Complex Pro warping, Follow Actions, and BPM/key metadata. Enable Generate MIDI as well if you want a separate MIDI project. Open the .als in Ableton 12+ — no manual import pass required.
Does Qie work with rekordbox for DJ sets?
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.
What are 8-bar loops and why are they useful?
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.
Is Qie Stem Slicer free?
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.
How does Qie compare to LALAL.AI, RipX, and Moises?
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.
Can Qie export stems as MIDI?
Yes, when Generate MIDI is enabled in Settings. Qie uses Spotify's basic-pitch for melodic stems (bass, melody, vocals) and librosa onset detection for drums, with General MIDI drum mapping. With Ableton export on, MIDI clips can land in the generated Live project as well as standalone files.
Does Qie work offline?
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.
How do I separate drums from a song?
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.
What audio formats does Qie support?
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).
