maximumHoldSeconds

Longest one drawing is held with no boundary at all, after which the next beat changes it.

Zero, the default, waits for a boundary however long that takes, which is the rule this director is built on: elapsed time is not musical evidence. An application that shows the picture to somebody usually wants a number here, because plenty of real music offers no boundary the detector will support. Measured over the five sample songs, one offered none at all in four minutes and the rest offered between two and six, so with zero the director can appear to do nothing on exactly the music a viewer is watching.

A change made this way still lands on a beat, and a boundary is still preferred whenever one arrives. Values below minimumHoldSeconds are treated as that minimum.
