Michiel van Loon was born in 1947 in The Hague. After 17 years in various positions at construction companies, he temporarily stopped working in 1982 to take care of his 3 children. His wife then provided the income. During that time he was busy with the restoration of a few player pianos and he studied piano technique. He has been a certified piano technician since 1991. In 2002 he was asked to help a disabled pianist to use the damper pedal again. With the help of various people, he has developed a system through which the damping can be operated with parts of the body other than the foot. Initially with parts from PianoDisc from the United States, later with parts from Laukhuff from Germany, among others. 12 pianists with disabilities in the Netherlands, 2 in the US and 1 in Italy can now operate the dampers with a small movement of the knee or by squeezing a pipette balloon with their lips. The system can be built into almost any upright piano or grand piano. There is also a stand-alone demonstration version that can be placed under a grand piano or in front of an upright piano.
