Verschueren Pipe Organ
A small two ranks pipe organ, which was used in a small church before. It has electrical keyers engaging electromagnetic valves for each single pipe.
This organ implements multiplex technology, re-using the 136 stopped and principal pipes for the eight stops, supplying 16', 8', 4 and 2' feet. A conventional organ with individual sets of pipes for each stop would need twice the pipes than this one. The lowest 16 foot pipes for the lowest octave are missing and are simulated by activating the 5th and 8th pipes.
Absolute wind power and not to compare with sampling technology! And rather loud this little monster.
