CueSync sends OSC to your Eos console in real time — fire cues, Go/Back through cue lists, set channel and submaster levels, and launch macros, all locked to the beat.
Eos speaks OSC out of the box. CueSync targets the standard /eos/ command surface — no plugins or middleware on the console.
Fire specific cues, or run Go and Back through a cue list on beat drops, energy changes, or BPM thresholds.
Map audio energy and frequency bands to Eos channels and submasters for live, music-reactive intensity.
CueSync locks to beat phase, not just BPM — cues land on the exact downbeat every time.
Save Eos routing per venue and recall it instantly between shows.
Monitor the Eos connection, active cues, and every output from a single HUD.
Engineering facts
The load-bearing claims behind CueSync's ETC Eos integration. Numbers, named subsystems, test references — the things you can verify before the show.
MSC messages are emitted as SysEx in the RP-002 envelope (GO, STOP, RESUME, GOTO_CUE) with a 128-byte cap enforced before send. Generic OSC output takes any address and argument list you define, so a console CueSync has no dedicated driver for is still reachable. Source: MscProtocol.kt.
CueSync fires `/eos/key/go_0` — the physical [Go] key — rather than `/eos/cue/fire`, because Eos's fire address takes an explicit cue argument and behaves differently mid-stack. Console state is read back from `/eos/out/active/cue` and `/eos/out/show/name`. Default port 3032. Source: EtcEosProtocol.kt.
CueSync evaluates beat events from Pioneer PRO DJ LINK on a sub-5 millisecond budget on the cue-evaluation path, and reports the budget-violation rate on screen. End-to-end beat-to-fixture latency depends on the operator's protocol chain and venue network; the CueSync portion of that chain is engineered to a strict sub-5-millisecond budget and continuously regression-tested. The OSC send budget is under 2 milliseconds.
CueSync ships 15 output protocols from a single desktop application: GrandMA2 (Telnet and OSC), GrandMA3 (TCP OSC and UDP OSC), Avolites Titan, ETC Eos, ChamSys MagicQ, Resolume, disguise (d3), VIOSO Player/Show, AV Stumpfl Pixera, TouchDesigner, Unreal Engine 5, QLab (TCP and UDP), MIDI Show Control, Pangolin Beyond, and Custom OSC. Every CueSync edition includes every protocol.
