ReadonlyclampedThe wanted delay fell outside the travel. Negative means THIS output is already the LATE one and cannot be advanced — the reference is the loudspeaker to move, and the surface says so rather than applying half a fix.
ReadonlydelayThe value for that side's delayMs<Role>, inside the declared travel.
ReadonlysideThe SIDE of the destination this correction is spent on — delayMsL / delayMsR /
delayMsC (#845). A loudspeaker is one BOX on one PORT, and the box beside it on the other
port of the same leg keeps whatever it was measured at: spending a correction on the whole
destination would move both boxes together and the difference would never close.
What APPLY would write on one SIDE of one output's leg, and whether the desk can write it.
