Compatible Loop Discovery
Loops: Find a Musical Neighbour
Matching numbers in a browser column is only the first handshake. Two loops both tagged 100 BPM and F Minor can still sound stiff or muddy together if their internal micro-timing or chord extensions collide.
Use the compatibility decision tree and harmonic checks below to pair drums, basslines, and melodic phrases that sound as though they were recorded in the same room by the same band.

The Four-Step Loop Compatibility Decision Tree
Before discarding a promising sample, walk through these four listening checkpoints in order:
Subdivision & Pocket Check
Is the anchor loop playing straight sixteenth notes,MPC-style 62% swing, or a triplet shuffle? Pairing a heavily swung hi-hat loop with a dead-straight quantized synth arpeggio creates rhythmic friction on every off-beat. Slice the stiffer loop to transients and apply matching groove quantization.
Stretch Tolerance Window
Modern warping algorithms (such as Élastique Pro) handle tempo shifts cleanly within ±8% to ±12% of the original BPM. Stretching a 90 BPM acoustic drum break up to 128 BPM smears the transient snap; instead, slice the break into individual hits or pitch it up naturally like a turntable.
Harmonic Neighbour Translation
Don't limit searches to identical key labels. A loop in A Minor shares all seven scale notes with C Major (its relative major), and borrows smoothly from E Minor or D Minor (a fifth above or below). Transposing a candidate loop by ±1 or ±2 semitones rarely degrades formant character.
Density & Register Carve
If your anchor loop is a busy, syncopated bassline, look for a chord loop that plays long, sparse whole notes in the upper midrange. Contrast in rhythmic activity keeps the ear engaged without requiring heavy-handed EQ cuts.
Practical Relative-Key Pairing Reference
When browsing for melodic companions to a loop you already love, keep this quick translation table beside your desk. It pairs standard musical key labels with Camelot wheel codes and safe transposition targets:
| Anchor Loop Key | Camelot Code | Zero-Transpose Relative Match | Fifth Up / Down Neighbours | ±2 Semitone Pitch-Shift Pool |
|---|---|---|---|---|
| A Minor | 8A | C Major (8B) | E Minor (9A) / D Minor (7A) | G Minor, G# Minor, A# Minor, B Minor |
| C Minor | 5A | Eb Major (5B) | G Minor (6A) / F Minor (4A) | Bb Minor, B Minor, C# Minor, D Minor |
| F Minor | 4A | Ab Major (4B) | C Minor (5A) / Bb Minor (3A) | Eb Minor, E Minor, F# Minor, G Minor |
| G Major | 9B | E Minor (9A) | D Major (10B) / C Major (8B) | F Major, F# Major, Ab Major, A Major |
