Rabstejn - Bellows

Three wedge bellows were designed to supply the wind for the entire instrument. The operation is enabled only in the Advanced version of Hauptwerk. Hidden calcants (in fact, a detachable blower) inflates the bellows which then fall slowly as the organ consumes the air. When the bellows are empty, the blower is set to work and inflates the bellows again. By clicking at the topmost blue dot above each set of bellows indicator, each set of bellows may be disabled. The momentaneous pressure inside each set of bellows and also that in the windchests is shown.

The Auslass-Ventil in the bottom left corner may be opened partially or fully (with a midi continuous controller or via mouse clicks) to increase the wind leakage to set the air inside the organ more unstable if desired.

The bottom right corner offers two switches, the blower switch (disabling it would eventually cause the organ stop sounding when all the bellows are empty), and the Klappen. When disabled, different mechanism is used to feed the windchests which again may cause different wind fluctuations.
