Hello from Southern California, I am new to this wonderful technology of computer aided pianos and was wondering the purpose of the 'hammer sensors'. Thanks in advance. Best regards.....

The hammer sensors are working together with the key sensors, together they measure the movements of hammer and key to have the best information of playing.

the unique feature of the disklavier is that unlike a player piano that plays all notes at the same volume the yamaha can actually record the pressure and release speed of the musician henceforth a "real" recording Shay Hovell Licensed Realtor Iowa <A HREF="www.ottumwahomes.net">www.ottumwahomes.net</A> 641-682-6030 Office 641-682-2529 Home 641-777-1556 Cell

There have been player pianos since the turn of the century
that automatically vary the dynamics. They are known as reproducing
pianos. Standard player pianos, when played properly also produce a
realistic performance under the control of the operator.
Check out my web site for more information and for some sample recordings of these reproducing performances. I sell cds of emulations of the original performances that can be played on the Disklavier as well as many other systems.

This ties into the difference between the Disklavier Pro and the standard Disklaviers (including the Mark III series). My understanding is that the regular Disklaviers can be calibrated via a service mode procedure, so that the drive system configures its table of how hard individual notes must be struck to achieve certain velocities. This sets up the internal tables of how hard individual solenoids must strike each note to produce certain hammer velocities. Also, to some degree, the standard Disklaviers self-calibrate as they play. For example, the system is instructed to strike a note at a particular velocity. For each note struck, it measures the final resulting hammer shank velocity. Based on the measured data, it knows whether it struck too hard or too softly relative to the requested velocity, and can adjust the internal table to try and play that note more accurately next time. If my understanding is correct, the Disklavier Pro mechanism differs in that it has a closed-loop feedback system that permits the hammer position to be monitored _continuously_ while a note is being struck and the solenoid duty cycle adjusted on the fly to compensate for any variation from the velocity requested. Thus, the Disklavier Pro plays more accurately because the closed-loop system enables it to play each note with the exact velocity requested (or very close to it) instead of firing the solenoid with a best guess and working to "get it right next time", the way the standard Disklaviers function. Because of the improved accuracy of the Pro's drive mechanism, the system supports 10 bits of velocity data (1023 levels) instead of the 7 (127 levels) supported by the non-Pro units. The pedal system employs a similar feedback system and on the Pro is capable of reproducing 128 different positions for each pedal vs. 16 on the non-Pro units. If someone from Yamaha could confirm this description is correct or offer additional information, I would appreciate it. I have spoken with several dealers and none have been given much technical information about either system.
