What Is Show Control Software?
Show control software coordinates and automates the technical elements of an exhibit or attraction — playback, lighting, audio, video, and effects — so they fire together, on cue, every time. In a museum, it is what turns on a gallery in the morning, runs each exhibit's media in sync, and shuts everything down at night, without staff touching individual devices.
There are two ends of this market, and choosing the wrong one wastes money:
- Timeline/SMPTE show control (Medialon, 7thSense, Alcorn McBride, QLab) — frame-accurate synchronization of complex multimedia for immersive attractions, theme parks, and high-end installations.
- Device control & scene playback (SoftControl and similar) — centralized power, source, scene, and scheduled control of the projectors, screens, audio, and lighting in a gallery, with content triggering.
Most museums and galleries need the second far more often than the first. This guide covers both, names the leading tools, and helps you avoid over-buying.
The Main Show Control Platforms
| Platform | Type | Best for | Cost |
|---|---|---|---|
| Medialon (7thSense) | Timeline/SMPTE | Immersive attractions, theme parks | High |
| Alcorn McBride | Show control + playback | Museums/attractions, A/V playback | High |
| QLab | Cue-based (Mac) | Theater, projection, smaller installs | Free tier / paid |
| Watchout / AVStumpfl | Media server + show control | Projection-heavy installs | Mid–High |
| V-Control | Open source | Budget device control | Free |
| SoftControl | Software device control | Galleries, exhibit halls, scenes & scheduling | Perpetual license |
The high-end platforms exist for frame-accurate, safety-critical shows. For a typical gallery — power devices on/off, run scenes, trigger content, schedule open/close — a software device-control system delivers what you need at a fraction of the cost.
What Museums Actually Need from Show Control
- Scene modes — one button for "open," "guided tour," "self-serve," and "close." (See one-touch open/close.)
- Scheduled automation — power exhibits up before opening and down after closing, unattended.
- Reliable offline operation — galleries run on isolated networks; the control layer must work without the cloud.
- Mixed-brand device control — old and new equipment side by side, over serial, network, and PJLink.
- Self-editable interface — curators change layouts often; waiting on a programmer for every tweak is painful.
Where SoftControl Fits
SoftControl is a software-based control system for exactly the device-control side of museum show control. It runs on a Windows PC or Android tablet, builds interfaces with a drag-and-drop editor (no programming), triggers content through its player, runs scheduled scenes, and works offline.
- Great for: galleries, exhibit halls, corporate showrooms, cultural centers — power, source, scene, and schedule control of mixed devices.
- Not a replacement for: frame-accurate SMPTE/timecode synchronization of complex immersive shows — that remains Medialon/Alcorn/QLab territory. Be honest about which you need.

How to Choose
- Frame-accurate, safety-critical, immersive attraction → Medialon, Alcorn McBride, or QLab.
- Gallery/exhibit device control, scenes, scheduling, tight budget → software device control like SoftControl.
- Projection-mapping heavy → a media server (Watchout/AVStumpfl) plus device control.
FAQ
What software do museums use for show control?
High-end immersive installs use Medialon, 7thSense, Alcorn McBride, or QLab for timeline synchronization. Many galleries use simpler software-based device control (such as SoftControl) for power, scenes, and scheduling.
Is there an affordable Medialon alternative?
For frame-accurate timeline shows, QLab and V-Control are lower-cost options. For gallery device control and scene playback, a software control system like SoftControl is dramatically cheaper because it runs on hardware you already own.
Can show control run offline?
Yes. Permanent museum installs typically run on isolated networks, and well-designed control software operates fully offline.
