Swellbox and crescendo wheel
Swellboxes are enclosures with vertical venetian blind-type shutters controlled by the swell pedals (or ‘swell shoes’). As a given shutter closes, the pipes contained in that swellbox will sound quieter and darker (with lesser amounts of high overtones). The Kispest Organ’s swellbox characteristics, through careful measurement and modeling, are brought to life with breathtaking realism. The swellbox can be operated by using the Sweller pedal (left pedal on the figure). Its operating direction can be set on the Right Page.
The crescendo wheel is an axially rotating drum operated by foot control, and is used in place of a conventional crescendo pedal. The wheel is positioned to the left of the foot-operated swellbox pedals. Sliding (rolling) it forward from position 00 to a higher position triggers stops in a preset user-defined manner, according to the sequence contained in the respective Crescendo Program.
The Kispest organ’s multi-purpose LED display indicates the current crescendo frame status when the wheel is moved. Once you turn on the organ, c00 is shown which corresponds to the Crescendo wheel’s 00 position with the crescendo wheel disabled. This means that once you move the wheel there will be no change to the sound. The reason that this is made so is that this way you can go directly to the frame you need and engage the wheel at the position that you like directly.
Once you enable the crescendo wheel (by making sure that the Henger Ki button is not pressed) the display will show a small letter c (i.e. c00) instead of C00.
