Sandbox is a mod of BeepBox published on June 15, 2017, by Parad0x, Theepicosity, and FillyGroove. It is the second mod to be released, following ModBox. Like ModBox, Sandbox is a general content mod, adding various features. ModBox and Sandbox have a close history, as they often copied features between each other.

Sandbox is well known for its “duty cycle” instrument type, which later returns in Unbox. It also adds various presets referencing waveforms/presets from other mods, and various other smaller things.


None of Sandbox's editions have a song player.

Sandbox is the main edition of Sandbox.

Sandbox 1.2.1 Archive is the archived edition of Sandbox 1.2.1.

Sandbox 3.0 Archive is the archived edition of Sandbox 3.0.
