Chiff Dynamics
Blowing an organ pipe creates an effect known as chiff. This forms an essential component of the overall sound. In most electronic organs chiff is created by computer simulation. The result ranges from poor to reasonable. In Johannus organs, however, the original recording of organ pipes is used. Each time a different key is pressed, the fundamental tone is preceded by chiff. Moving air remains briefly in the pipe when the note is released. When the same key is pressed again in quick succession, this remaining air flow causes part of the chiff to be lost depending on the speed of repetition. Although this effect is typical of a pipe organ, it was previously lacking in pipeless digital organs.
Temperaments
