Variable Pitch pipe. The earliest pitch pipes were instruments similar to the recorder, but rather than finger holes, they had a plunger like a slide whistle's (also known as a swanee whistle) making it essentially a type of Slide Whistle. The pipe was generally made of wood with a square bore, and the plunger was leather-coated.
The pitch of individual pipes can be randomly modified when a sample is loaded into memory. If multiple loop points are provided, in the sustain section of a sample, these are selected randomly. Additionally, Hauptwerk simulates some other effects, such as wind turbulence, using randomization during playback.
On a slotted metal pipe, some or all of the metal cut out to make the slot is rolled up so the slot can effectively be shortened or lengthened, thus changing the pitch of the pipe. On a slotted wooden pipe, a wooden slider is provided to shorten or lengthen the slot. A stopped pipe (wood or metal) is usually tuned by moving its stopper up or down.
Digital organs are a viable alternative for churches that may have a pipe organ and can no longer afford to maintain it. Some pipe organs, on the other hand, might be playable without major rebuilding for many decades. However the high initial cost, and longer lead time to design, build, and "voice" pipe organs has limited their production.

The first use of pedals on a pipe organ grew out of the need to hold bass drone notes, to support the polyphonic musical styles that predominated in the Renaissance. Indeed, the term pedal point, which refers to a prolonged bass tone under changing upper harmonies, derives from the use of the organ pedalboard to hold sustained bass notes. [2]
A common control on contemporary keyboards is the pitch bend wheel, adjusting the pitch of a note usually in the range of 2 semitones. The pitch bend wheel is usually on the left of the keyboard and is a spring-loaded potentiometer. Some keyboards include a joystick, which often combines all the aforementioned functions in one control unit.
