Invalid mixer document

A mixer document cannot be built: bus names, outputs, ducking sources, numbers or state targets are invalid.

#Common causes

• Duplicate or empty bus names, an unknown output bus, or a bus that ducks by itself or an unknown bus.
• Outputs or duck sources form a cycle; a mix state names an unknown bus; the initial state does not exist.

#Fixes

• Correct the named record with property.set; every bus must reach master.

• Remove the cycle or the unknown reference.
