PTD analyses/ corrects the transmission ratio.

- Beside all inertia differences most pianos play with an uneven dynamic touch because in most factories the 88 hammers are not corrected into a smooth decreasing weightcurve.
Total cost for a PTD analyse with the design will be 484,00 EUR Finishing the PTD will cost 2.662,00 EUR If a new capstan line is needed a supplement of 605,00 EUR will be charged
I include in this price: - Transport to my workshop and back - Full regulation of the action with correction of the keydip - PTD certificate and logo - Terms of delivery are around three weeks - Five years warranty on my PTD work

The PTD academy Europe  exists 10 years

Today everybody can easely acces all PTD information.

I specialy refer to the articles on Davids site and to Mario Igrecs excellent book ‘ Pianos Inside Out’ chapter 9
When the pianist hits the key and catapults the hammer towards the string, he makes connection with the amount of inertia in the mechanism. This resistance of mass he feels increases with the acceleration of the hammer. When he plays soft this resistance is small, just above +/- 50 grf but, when playing more forté he will need considerably more force to overcome the increased touchweight.
First the pianist feels in his touch a brief contact moment of +/- 10 gr friction = the friction of the parts in the mechanism. Instantly afterwards he feels the inertia of the hammer and key in motion.
This inertia can differ considerably from piano to piano, because piano actions are produced with various combinations of ratios and hammer weight. There is currently no standard.
With PTD we choose the combinations which will produce an inertia the pianist can optimally control in his touch. After a PTD analysis of the transmission a correction is often necessary. .
for pianists and technicians We all keep learning with your comments and questions, thank you for your important participation.

Within my forty years of pianotuning I played and analysed many different pianos and could compare the same piano before and after a PTD calibration. Since 2003 I have been installing more than fifty PrecisionTouchDesigns on Steinway, Yamaha, Kawai, Bösendorfer, Bechstein, Blüthner, Ibach, Schimmel, Seiler and other brands. With this expertise I can easely claim that Precision Touch Design is often the best solution for upgrading to a more pleasant touch and tone getting more value out of your piano.

In their training pianists develop techniqual skills to be able to adapt to different piano touches. - Some pianos feel too light, they have a low inertia and are difficult to master,this pianos play with you and put you way out of control.
- Other pianos have a high inertia, their hammers are too heavy and their keys are overloaded with leads. They react too slow, feel heavy, are exhausting and are a risk for injuries.
