STARTING POINT
The central challenge
Ordering a large library manually takes time, yet a fully automatic sequence cannot understand dramaturgy, the moment in the show or personal taste.
CASE STUDY APPLICATIONS
ENERGY MIX
Data-informed set flow, with the final decision left to the DJ.
Case study of ENERGY MIX / CANDICE SET PLANNER: a local macOS application for analysing energy, structure and harmonic transitions in a DJ set.

ABOUT THE PROJECT
Data-informed set flow, with the final decision left to the DJ.
ENERGY MIX is the portfolio name for CANDICE SET PLANNER, a local macOS tool that helps arrange tracks by energy, structure and harmonic compatibility without uploading the music library to an external server.
GOAL AND SOLUTION
From a real need to a working whole.
DESIGNED SOLUTION
One connected solution
Local analysis, constraints, locks and alternatives form a workflow where the engine proposes options and the DJ can listen, adjust or reject them.
OUR ROLE AND PROCESS
End-to-end work. One responsibility.
- Product strategy and process analysis
- UX/UI and prototyping
- Architecture and development
- Data model and integrations
- Testing and security
- Deployment and further development
Map the work
We separate the real problem from steps created only by limitations of existing tools.
Design the system
We define the data model, key scenarios and an interface that remains clear in daily use.
Build the product
Frontend, logic, data and integrations come together in one working system.
Validate real operation
We test critical paths, access, error states and realistic use before further development.
WHAT THE APPLICATION DOES
Important functions without unnecessary layers.
DJ library import
The application reads Rekordbox TXT, CSV, XML and M3U8 and unifies the inputs for further work.
Energy and structure
Local analysis follows the progression of each track to inform the shape of the set.
Harmonic transitions
Camelot logic helps find combinations worth considering as transition candidates.
Constraints and locks
Selected tracks or positions can be locked while the system optimises the rest.
Alternatives and transition listening
Proposals can be compared and assessed by ear before the final export.
Playlist export
The finished sequence can be exported as M3U8, TXT, TSV or CSV for the next part of the workflow.
TECHNOLOGY
A technical foundation shaped by the project.
The verified stack combines SwiftUI, Swift, Python, OR-Tools, NumPy, Core Audio, Beat This, MusiCNN. Each technology was selected for the role it performs in the product, with maintainability and real operation in mind.

OUTCOME
A focused digital result built around real use.
ENERGY MIX brings import, analysis, sequence proposals, transition previews and export into one local tool while keeping musical judgement with the person behind the set.
