The Classroom Pump Organ was made around 1880 by C.A.V. Lundholm of Stockholm in Sweden. It was
used as a Classroom Organ at Whitlockska Samskolan, a private education centre in Stockholm,
between 1878 and 1978.

The organ is distinctive for its use of air pressure, as opposed to the more commonly found
suction mechanism. The sound is produced by bellows pressing air through the reeds from the inside
out. This creates an open, clear and direct sound.

We sampled all notes on the organ, and extended its playable range to C1 – C6 from the original
C1 – C5. Additionally, we recorded the pump mechanism at different speeds. You can layer the sampled
pump mechanism with your performance, or trigger it directly from the GUI in our scripted program for
Kontakt 3+. When combined with scripted variations in note volume, the result is beautifully organic
and realistic. Our Kontakt 3+ program also enables creative chorus and harmony effects that go beyond
the possibilities of the original instrument.

If I wouldn't read the text above I would think they sampled an accordion or something like that. But, hey, that's the way this Classroom Pump Organ must sound.
