Common Quantum 7 errors & problems
What techs run into most, and what's usually behind it. The step-by-step fix for your exact unit is in Ask Roadie.
- Step-by-step fixGet the fix →
Aux send name will not display on the faders when the aux is on Sends-on-Faders
Likely cause: The name field was being parsed against the Stereo/Mono reserved prefixes; renaming avoids the collision until firmware is current.
- Step-by-step fixGet the fix →
Expected Optocore device (SD Rack, OrangeBox, other console) not showing up on the loop / missing I/O
Likely cause: The Optocore ring only maps devices that share a common fibre speed and non-conflicting IDs; a duplicate ID or speed mismatch silently drops a node from the map.

How to update Quantum 7 software and what the current version is
Likely cause: Running matched, current console + offline versions avoids showfile-compatibility and known-bug issues; V2242 is the confirmed current train.
- Step-by-step fixGet the fix →
Macros misbehave: wrong matrix send captured, or wrong macros fire from a snapshot after duplicating/deleting macros
Likely cause: These were logic errors in macro indexing/association corrected in later releases; re-capturing rebuilds the macro against the fixed code.
- Step-by-step fixGet the fix →
Optocore remap fails because two consoles disagree about who owns an output card
Likely cause: Remap only completes when all consoles share one consistent output-ownership map; broadcasting IDs syncs that map so no card is double-claimed or invisible.

Recording/playback (virtual soundcheck) into a laptop without extra hardware
Likely cause: UB MADI is a class-compliant USB audio interface built into the engine, so basic virtual soundcheck needs no external converter.

Reference: Quantum 7 core specifications
Likely cause: Baseline facts techs need for patching, rack counts, I/O planning and transport/rigging weight.

Remap Optocore still throws an error after loading a showfile built in the Offline editor
Likely cause: The console will not remap cleanly while the Con Send/Receive port numbers disagree with the actual network IDs on the loop; the offline-to-console ID mismatch is the single most common cause.

Video (e.g. camera/monitor feed) not passing between Quantum 7 engines over Optocore
Likely cause: Video-over-Optocore was a firmware capability gap, not a cabling fault; checking version prevents chasing a hardware problem that does not exist.
