Use NullPerator anywhere

NullPerator hardware, Web, and iOS use the same tracker screens, instruments, project format, and action names. Learn Shift, Option, Enter, and Play once, then move between devices without relearning the workflow.

The controls at a glance show the mappings for every platform. The rest of the manual uses the shared names Shift, Option, Enter, and Play, rather than splitting each task into three versions.

Keep a portable copy

Keep a second copy outside the device you compose on. Copy projects from the NullPerator hardware SD card, export a ZIP from the Web Files panel, or copy the NullPerator folder from iOS Files. Local app or browser storage should not be the only copy of important work.

See Files and compatibility when you want to move projects or samples by hand.
