Question 1

Is Ghost Arcade free to use?

Accepted Answer

Yes — fully free and open source. The Community edition (AGPL-3.0) gives you the full foundation: projection mapping, 11 layer types, 50+ effects, single-deck VJ launcher, MIDI control, mobile companion (iPad/phone), recording, ISF shader playground. Source on GitHub. No signup, no watermark, no expiry. Mac, Windows, Linux.

Question 2

Is Ghost Arcade open source?

Accepted Answer

The Community edition is open source under AGPL-3.0. Source code is on GitHub at github.com/riskcapital/ghost-arcade-community. The commercial Pro edition (which adds dual-deck VJ, A/B crossfader, macros, snapshots, AI generation, Spout/Syphon) is a separately maintained codebase under a commercial license.

Question 3

What is the difference between Community (free, open source) and Pro?

Accepted Answer

Community is free, AGPL-3.0 open source with the foundation surfaces (projection mapping, 11 layer types, 50+ effects, single-deck VJ launcher, MIDI, mobile companion, recording, shader playground). Pro adds the live-performance + AI surfaces: dual-deck VJ + A/B crossfader (10 transitions × 9 blend modes), 8-knob macro effect-bank, 16-slot snapshot bank, quantized clip launching, MIDI clock, Spout/Syphon, AI shader + video generation, keyframe timeline, plugin tab.

Question 4

Can I use the open-source Community edition commercially?

Accepted Answer

Yes. Commercial creative use is allowed under AGPL-3.0 — paid shows, client visuals, installations, recordings, streams, tutorials. The visuals you create with the app are yours. The AGPL applies to the source code itself: if you modify the source and run it on a network server, you must make the modified source available to users. See COMMERCIAL_USE.md in the repo for details.

Question 5

Do I need coding experience?

Accepted Answer

No. Everything is visual and interactive. Pick shaders from the library, drag effects onto layers, and adjust parameters with sliders. Pro adds AI generation that lets you describe what you want in plain English.

Question 6

What projectors work with Ghost Arcade?

Accepted Answer

Any projector that connects to your computer via HDMI, DisplayPort, or USB-C. Ghost Arcade outputs to any display your operating system recognizes, including multiple projectors simultaneously.

Question 7

Can I use it for live shows?

Accepted Answer

Absolutely. Both editions are built for live performance. Community has the single-deck clip launcher + Performer keyboard mode + MIDI mapping + mobile companion. Pro adds dual-deck with A/B crossfader, 8-knob macros, 16-slot snapshot scene bank, MIDI clock, and quantized launching for tight musical drops.

Question 8

Does it work with MIDI controllers?

Accepted Answer

Yes. Any MIDI controller works out of the box in both editions. Use learn mode to map any knob, fader, button, or pad to any parameter. Multi-device support with channel filtering. Pro adds MIDI clock receive + send (24 PPQN, sync to/from Ableton).

Question 9

The Community edition ships an AppImage for Linux. The commercial Pro edition is currently Mac + Windows only.
