Next-gen audio playout software for TV broadcast — a modern replacement for legacy cart machine software. Built for rock-solid performance.
Callie Grams is the next-generation audio playout machine for TV broadcast — a modern Grams machine for live production, and a true step up from legacy cart machine software. Built in Rust and fully cross-platform, Callie Grams brings a modern interface for organizing and triggering clips together, and a full Web API — with an easy migration path for your existing audio library. Take advantage of our early adopters discount and test for 10 days in our trial.
Traditional cart machine software served broadcast well, but much of it hasn’t kept up. Callie Grams is the up-to-date alternative: native support for today’s Windows, macOS and Linux, ultra-low-latency audio, built-in stem separation, and remote control from any browser. No more nursing machines on end-of-life operating systems, and no more rebuilding your library from scratch — Callie Grams can import your SpotOn playout packages directly, bringing your clips, colors and settings across with minimal downtime.
Chain clips together into Sequences and let Callie Grams run the rundown for you. Build a playout order — beds, stings, idents and voice tracks — and step through it hands-free, or let it roll automatically. Need clips firing in sync? Gang them and one press triggers the whole set together. And with Groups, clips that belong together replace each other — trigger a new clip in a Group and it automatically stops whatever else is playing in that Group, so you never get two beds or stings stacked on air. It’s the show-flow control legacy Grams software never gave you, right in the grid you already know.
Whether you know it as a soundboard, a cart machine or a Grams machine, Callie Grams does the job of playing in your music, stings and SFX with instant, reliable triggering. Written in Rust, it’s modern, future proof and cross-platform — and so efficient it doesn’t need expensive hardware. It’ll run happily on a laptop, making it great for portability and OBs, and it’ll take full advantage of the latest hardware when you have it. No more computers running old versions of Windows 7 or MacOSX. Whatever your flavour of OS, it will run!
Route every clip to its own output. SFX and Music can live on separate routes, with support for multichannel devices and Dante Virtual Soundcard.
If your computer sees the device, it works in Callie with ultra low latency.
Well of course! We love Streamdecks, so we built this in natively — you don’t even need to install the Elgato software, it runs straight out of the box.
We built seperations into the software. You can just load the song you want to use and get it to process an instrumental version right from inside the software — no internet connection needed, no costly AI online sites or CLI bashing needed to get the same result.
Already running SpotOn? You don’t need to rebuild your library from scratch. Callie Grams can import your existing SpotOn packages directly, bringing your clips and audio across so you can migrate your playout setup with minimal downtime.
Record audio straight into Callie Grams. Whether it’s a last-minute voiceover clip, a news actuality or something off air, you can capture it live and have it ready in a slot for instant playback — no round trip through a separate editor needed.
Callie Grams includes a built-in web interface so you can trigger clips, manage playback and switch projects from any browser on your network — perfect for remote operators or secondary control positions. Grab an iPad and connect to Callie Grams over the network to get a remote trigger pad.
Callie Grams exposes a full HTTP API, making it ready for integration with Bitfocus Companion. Map any clip, gang to a button on your Streamdeck or other supported hardware. You can even switch projects on the fly!
In Broadcast and Post Production, we know that we aren’t just one operating system — so we designed all our software to work on Windows, Mac or Linux. Why be constrained by your operating system determining what you can or cannot run? One product, three operating systems as standard.
