Robbie Rhodes writes about the 3 bar linkage in Duo-Art grands and the non-linear effect on knife valve movement. Does anyone know the effect of adjustment of the simpler upright duo-art linkage and the correct starting position? I have played around with it trying to compress and expand the dynamic...

•The flexures used to connect the linkages between the pneumatics and the whippen fingers of the Gulbransen-Dickinson late model players are made of thick buckskin (deer skin or elk skin). This is the only material that has the necessary density, as well as flexibility, to work properly. It is vital...

•Could anybody give me some advice about linking a computer to a Player Piano? I have no problems with how to make MIDI files from my digital piano, or how to activate the pneumatics using solenoids, but what is physically needed to go in-between the solenoids and the computer? Also thank you to eve...

•[ Re "James Watt & Watt's Linkage" Hi All -- I thought I had said about all that could be said about momentum, inertia, etc., after teaching physics for 30 years but I cannot contain myself upon seeing recent MMD entries. I am sure both gentlemen think they are correct in repeating for us what they...

•I have no idea what kind of linkage or slides may have been used, but this drawer-full of roll transport and stack is a very new idea to me, and very intriguing. I realize you are not interested in creating in- trigues but in finding a solution. So, if all else fails, it may be possible to reverse-...

•Lately on the MMD there were some links given to animated automatic music machines on YouTube at http://www.youtube.com/user/AnimusicLLC "Pipe Dream", the first big 'hit' of these animations from 2004, inspired Intel to sponsor making one this past year.

•I read Randy Bergum's article (linked in Robbie's notes) on repairing cracked Deagan chime tubes with great interest. It sounds like a comprehensive solution to this common problem with older chime tubes. http://www.octos.org/ooth/repairs/chimetube/chime_tube_repair.htm I have a 1914 set of Deagan ...

•(One in an occasional series.) The photo linked below shows a tool or jig I designed a few years ago and use maybe every six months or so. The only clues I will give are that it is made of oak wood, in one piece (neither of which are critical to its function) and is about 16 inches long. The first ...

•Marshall Jose (in MMDigest 221106) sent links to the MIDI file and a scanned label for "Murder, He Says" (which I appreciated very much) but anyone who is interested in this song should also see the Betty Hutton performance on YouTube: https://www.youtube.com/watch?v=8c3G1PTcIps It's from the film ...
