The Hold feature, which relates to Canons, prevents the canon dance from reverting back to the backing-animation when it has completed its Canon Interval time. In other words, it acts as if the Canon Interval was infinite.
Use the Hold feature prior to doing a Canon.
The other state, which is the default, is Released. So the Hold feature toggles between Hold and Release(d).
So to disable the Hold feature, press the Release button prior to doing a Canon. Note that pressing the Release button has no immediate effect until the next Canon.
Use the StopCanon button, on the same menu as the Hold button, to immediately manually trigger the Canon Animation to terminate and revert back to the backing-animation.
This Hold feature is really handy when you want the Canon Dance to be a pose, as a practical example.
