Question 1

What makes SetFlow different from manual set preparation?

Accepted Answer

SetFlow analyzes thousands of possible track combinations using the Camelot wheel for harmonic compatibility, BPM matching, and intelligent energy flow. What would take hours manually happens in seconds. The algorithm considers key relationships, tempo progression, genre coherence, and energy arcs simultaneously.

Question 2

Do I need DJ experience to use SetFlow?

Accepted Answer

Not at all! SetFlow is perfect for both beginners learning harmonic mixing and experienced DJs who want to save prep time. The algorithm handles the music theory while you focus on performance. Each transition comes with notes explaining why it works.

Question 3

What is AI Set Analysis?

Accepted Answer

AI Set Analysis (Pro) gives you detailed feedback on generated sets: mood tags, transition highlights, DJ cue notes, energy arc analysis, and risk warnings for tricky transitions. It helps you understand why the algorithm made each choice and how to perform the set. Access it from any set in History.

Question 4

How does the SetFlow algorithm work?

Accepted Answer

SetFlow uses a multi-factor scoring system to evaluate every possible track transition. Each transition is scored based on: Harmonic compatibility (35%), BPM compatibility (25%), Energy flow (15%), Genre coherence (15%), and Momentum bonuses (10%). The algorithm uses a greedy optimization with 2-track lookahead to build sets that flow naturally from start to finish.

Question 5

What are the five energy archetypes?

Accepted Answer

Journey: Full arc from warm intro (energy 3) through peak (energy 10) and back down. Perfect for headline sets. Peak Time: High energy throughout (8-10), ideal for main room slots. Warm-Up: Gradual build from low (2) to medium (8), perfect for opening. Cool-Down: Starts high (9) and descends to low (2-3), ideal for closing. Chill: Maintains low-medium energy (3-4) throughout, perfect for lounges or afterparties.

Question 6

What is the Camelot wheel and how does SetFlow use it?

Accepted Answer

The Camelot wheel is a colour-coded system that simplifies musical key compatibility. Keys are labeled 1A-12A (minor) and 1B-12B (major). You can mix tracks with the same code, move ±1 position, or switch between A and B versions for an emotional shift. SetFlow scores transitions automatically: Same key = 100 points, Adjacent keys (±1) = 90 points, Relative major/minor = 95 points. It also rewards energy boost moves during peak moments.

Question 7

How does genre matching work?

Accepted Answer

SetFlow groups genres into families: House (tech house, deep house, progressive, etc.), Techno (hard techno, melodic, minimal, etc.), Trance (progressive, psytrance, uplifting, etc.), Bass (drum & bass, dubstep, etc.), Disco (nu-disco, funk, etc.), and more. Tracks in the same family get 95% compatibility. Cross-family mixing is scored based on real-world DJ practices (e.g., House↔Techno = 85%, House↔Trance = 60%).

Question 8

Can I mix tracks with different BPMs?

Accepted Answer

Yes! Most DJ software handles BPM syncing, so small differences are seamless. SetFlow treats transitions within ±2% as perfect (e.g., 124→126 BPM — dancers won't notice), ±4% as good, and up to ±8% as acceptable with a well-timed breakdown or build. The algorithm avoids jarring tempo jumps while still keeping your sets interesting.

Question 9

How does SetFlow handle energy curves?

Accepted Answer

Each energy profile (Journey, Peak Time, Warm Up, Chill, Cool Down) has a predefined curve. SetFlow matches tracks to the target energy at each point in your set, creating smooth builds and drops that keep the dance floor moving. Pro users can also design fully custom curves with the Set Planning Canvas.

Question 10

What makes a high Flow Score?

Accepted Answer

Flow Score combines three metrics: Harmonic Flow (40%) - how well keys transition using Camelot rules, BPM Flow (30%) - smoothness of tempo changes, and Energy Arc (30%) - whether the set follows the expected energy curve with a proper peak. A score above 90% indicates professional-grade mixing. Most SetFlow sets achieve 95%+ because the algorithm optimizes for all three factors simultaneously.

Question 11

Can I create genre-blending sets?

Accepted Answer

Absolutely! Select multiple genres when generating - SetFlow will find harmonic and BPM connections between different styles. The algorithm scores cross-genre transitions based on real-world DJ practices (e.g., House↔Techno works well, but House↔DnB needs care).

Question 12

How do I avoid repetitive sets?

Accepted Answer

Try different energy profiles for variety. Use the ratings filter to include only your best tracks. SetFlow also enforces key variety - Journey sets require 4+ different keys, ensuring musical progression throughout.

Question 13

What is the Playlist Builder?

Accepted Answer

The Playlist Builder (under Playlists) lets you manually build sets with intelligent suggestions. Add any track, and SetFlow suggests harmonically compatible next tracks scored by key, BPM, energy, and genre. Great for fine-tuned control while still benefiting from harmonic analysis.

Question 14

How do I use the ratings filter?

Accepted Answer

When generating a set, you can filter by minimum rating (1-5 stars). This uses your Rekordbox ratings to include only your favourite tracks. Perfect for gigs where you want your A-list material. Note: tracks without ratings are excluded when filtering.

Question 15

What are transition notes?

Accepted Answer

Each track in a generated set includes transition notes - suggestions like "Perfect key match, smooth BPM transition" or "Energy building, mix in highs". These help you understand why the algorithm chose each transition and how to execute it. View them in the expanded set view.

Question 16

What are Crates and how do I use them?

Accepted Answer

Crates are custom collections for organising your library — think of them like folders or playlists. Manual crates let you hand-pick tracks (available on all tiers: Trial gets 3, Hobby 10, Pro unlimited). Pro users also get Smart Crates that auto-populate based on filters like genre, BPM range, energy level, key, and rating. Click any crate in the Library sidebar to filter your view to just those tracks.

Question 17

What is the Set Planning Canvas?

Accepted Answer

The Set Planning Canvas (Pro) lets you design custom energy curves beyond the 5 presets. Split your set into 2–6 named sections (e.g., "Intro", "Build", "Peak", "Cooldown"), set a target energy for each, and see a live preview of the curve. Start from a template or build from scratch. The algorithm then follows your custom plan instead of a preset archetype.

Question 18

Why do I see duplicates after importing?

Accepted Answer

SetFlow detects duplicates by matching track title + artist. If you see duplicates, they may be different versions (remixes, edits) with slightly different names. Clean up in Rekordbox before exporting for best results, or use bulk delete in SetFlow.

Question 19

My import is taking forever. What should I do?

Accepted Answer

Large imports (1000+ tracks) run in batches to avoid timeouts. Keep the tab active and visible. If it fails partway, simply retry - already imported tracks are skipped automatically. For very large libraries, consider importing in smaller batches.

Question 20

Why is my library empty after refresh?

Accepted Answer

Don't worry! SetFlow auto-syncs from the cloud when you're signed in. Wait a few seconds and your library will reload. If it persists, try signing out and back in.

Question 21

How does the History feature work?

Accepted Answer

All generated sets are saved in History. You can rename sets, expand to see full tracklists, reorder tracks via drag-and-drop, and re-export anytime. Sets sync across devices when signed in. Trial users can view their last 3 sets, Hobby users 10, Pro unlimited.

Question 22

Can I edit a generated set?

Accepted Answer

Yes! In History, expand any set and drag tracks to reorder them. Changes save automatically. For more control, use the Playlist Builder to manually construct sets with harmonic suggestions.

Question 23

What are the differences between Trial, Hobby, and Pro?
