Indexed by what you notice, not by what the subsystem is called — because when something is wrong you know there's no sound, not that it's a routing problem.
6 of the 9 problems below are not faults. They are documented behaviour that looks like a fault, and they are marked working as designed. “Your unit is fine” is a useful answer and nobody publishes it.

Helix Stadium Owner's Manual 1.3.2Holding the lit output button disables the knob so it cannot be knocked on stage. Hold it again to unlock.
Helix Stadium Floor Cheat Sheet (Rev A)Every Clone block is mono, and anything stereo before one gets summed. Move your stereo effects after the clone.
