Studio Apps

The Figure 53 Studio is where we share software, source code, and experiments. Everything in the Studio is free. We hope you enjoy it!

Please note we can not provide support for Studio Apps.

Ultrasonic App Icon


A media manager and music library.

Ultrasonic takes the radical position that files and filesystems are actually rather useful. (And not to be messed with without your consent.)

Warning: Ultrasonic is an experiment! We enjoy hacking on it but you should consider it an early alpha.

Streamers App Icon


Visual cues for film scoring, ADR, and Foley.

Overlaying streamers and punches once involved expensive, inflexible, resolution-limited hardware and excessive setup time in software. Streamers changes that by bringing the overlay and scheduling of visual events and timecode-synced video playback into one affordable, customizable, and HD-capable software package.

Lockstep App Icon


LTC synchronization, no hardware needed.

Lockstep allows you to sync your computer to incoming timecode, without expensive hardware. Unlike some devices that only work with proprietary software, Lockstep generates MIDI timecode for any MTC-enabled sequencer.
