Qiē Stem Slicer
[ “chee-eh” | Qiē 切 meaning “to slice” ]
Meet Qiē Stem Slicer — a groundbreaking creative music production tool that slices your favorite songs into 8 full stems [Bass, Melody, Vocal, Full Drums along with Kick, Snare, Cymbal, Tom] and then into production ready 8 bar loops labeled by BPM, key (Western & Camelot Notation), bar # & audio energy density.
Drag any song into Qiē and use its optimized GUI (faster than any DAW) to find the exact BPM of your song within seconds to perfectly grid your track. Hit the Process Audio button then create perfect 8 bar loops (labeled by BPM and Key) from your favorite songs.
Qiē is a music production secret weapon — create an organized loop library (labeled by BPM, Key, Bar Number and Energy Level) built on music you like. Work on new productions and easily search new loops to help you come up with new melodic and drum motifs to spark new musical ideas.

Endless Possibilities
Qiē goes beyond just a stem separator by also creating organized 8 bar loops built on music you love to inspire completely original music production. In many DAWs (like Ableton), you can preview these loops in the same BPM as your new song.
Drum Example
Send a couple of tracks into Qiē and start a new project at a new tempo, take the cymbal loop from a 160 BPM jungle track, the snare from a 90 BPM hip hop boom bap track, the kick from a 130 BPM broken beat techno – send each stem segment into a plugin FX, mangle it up, glue them all together and create a completely unique beat.
Melodic Example
Start a song in let's say C minor (5A), let's say you've got a chord progression already laid out. Search your loops library (filled with Qiē loops from songs you love) for "5A" to find a bass line, a synth sequence (labeled _other). I can even take something in F# Minor 11A and polyphonically retune it. Find a loop and convert it to MIDI just for the notes. Throw three melodic loops within circle of fifths of each other: 5A, 4A and 5B into a sampler, play middle C, apply a gate sequencer effect on it, mangle it and know you'll be in key. I mean the possibilities are endless.
Other Creative Uses
- Send vinyl recordings into Qiē for 8 layers and load them into hardware samplers (MPC, Octatrack, Drum machines)
- Study the arrangements of songs – analyze melody, harmony, drums much easier with stem separation
- Add harmonic / drum layers to live and DJ sets.

“Never heard such clear stem slicing before. This has been essential for me when I want to strip out specific parts of an instrumental that many programs can't do without sounding like trash. A really nice program to use, too.”
“Love this freeking app. Such an underrated and essential tool for any creative audio workflow wanting to work with stem separation and samples in 2025”
