Lumicrowd at the live music experience "De Onderstroom"
Our first realistic pilot with live music, visuals and DMX lighting. The goal:
validate how smartphones can contribute to a deeper, interactive experience in
an artistic context.
Stage setup during the "De Onderstroom" pilot.
Event type
Live music + visuals
Attendance
±40
Goal
Immersive experience
Pipeline
DMX -> Lumicrowd -> phones
Context of the event
During De Onderstroom, Lumicrowd was used as a digital extension of the light
show. Alongside projections and classic DMX lighting, the audience was able to
become part of the visual whole through their smartphones.
The setup
DMX lighting driven by QLC+
Lumicrowd middleware translating DMX data into web visuals
Smartphones acting as real-time "pixels" in the room
This allowed the colour of the room lighting to be extended, in real time, to
the audience.
What worked well
The core technology works
After configuration, the full chain ran stably: DMX -> Lumicrowd -> smartphones.
Synchronisation across phones
Devices showed the same colours and effects with no visible drift between them.
Integration with the existing light show
Lumicrowd blended visually with the atmosphere in the room and added extra depth to the experience.
Challenges and insights
1) Configuration complexity (DMX mapping)
A mistake in channel assignment initially caused no colour on the phones. Insight: mapping must be simpler and less error-prone.
2) Audience participation
Participation stayed limited because the interaction was not introduced strongly enough. Insight: onboarding and active guidance are crucial.
3) Event-context fit
In a strongly artistic setting, phone use can also feel like a distraction. Insight: explicitly evaluate the format fit of Lumicrowd per event type.
4) Latency vs physical lighting
Phone-to-phone sync was good, but next to instant physical DMX fixtures a small delay remained visible.
5) Device-specific issues
Fullscreen did not behave predictably in every iPhone scenario; platform UX remains a focus point.
Key learnings
The technology works in a live context
Setup and configuration must be more robust
The audience needs active guidance
Not every event type is a good fit
Latency and UX remain a priority
Device variation needs extra attention
Conclusion and next steps
This pilot confirms that Lumicrowd is technically ready to add audience
interaction to live events through smartphones. The next focus is simplicity of
setup, better onboarding and further real-time optimisation.
