Cadence keeps its own disciplined clock. It syncs to an NTP server, learns how fast your Mac's clock drifts, and eases in corrections, then feeds that one time to every output it drives.
Use Apple (the default), Google, Cloudflare, NIST, the NTP Pool or your own server. Apply checks the server before switching.
It takes a quick burst of samples, keeps the steadiest one, and checks again every 64 seconds all show long.
Displays, NDI®, SDI, web pages, the cloud and wall clocks all read the same disciplined time.
Cadence itself, running a demo show. Clips are recorded in real time from Cadence's own renderer.
Small errors (under 100 ms) are eased in at no more than half a millisecond per second, so a live countdown doesn't visibly jump. Bigger errors are corrected at once.
Every Mac's clock runs a little fast or slow. Cadence measures that drift and corrects for it between syncs.
Cadence corrects its own clock and never changes the Mac's system time.
The status line shows NTP locked with the live offset, holdover on the last sync, or unreachable on the system clock. It never pretends to be locked.
Drive TimeMachines PoE, Wi-Fi and dot-matrix clocks from any Cadence timer. Find them on your network, and they follow every start and stop.
Decode LTC from any audio input, with the frame rate detected automatically, and drive a clock straight from the house timecode.
Video outputs (NDI, SDI) run at 59.94 fps. Web and cloud pages refresh 10 times a second, and TimeMachines clocks follow closely but not to the frame. Several Macs agree by locking to the same NTP server; they don't sync to each other. Timecode is LTC in only (no LTC out, MTC or PTP).
Yes, when they use the same NTP server: each one locks to it independently. They don't sync to each other.
Not for normal corrections. Errors under 100 ms are eased in gradually. Only a large error, such as the first lock, is applied at once.
No. It keeps its own disciplined clock and leaves the system time alone.
Cadence carries on in holdover from its last sync, and the status line says so. If it can't reach a server at all, it says so and uses the system clock.
TimeMachines PoE, Wi-Fi and dot-matrix clocks, over their own network protocol.
It reads LTC from an audio input. It doesn't output LTC, MTC or PTP.
The Cadence beta is free: every feature unlocked for 2 months, on up to 2 Macs.
