•Several questions have been posed regarding the "WindPlay" software which I designed and wrote. I thought a description would be helpful. "WindPlay" provides a window on a "play list" on which one can "drag and drop" roll image files. As each file is dropped onto the list, the roll title, type, tem...

•Robbie, you wrote [in a comment in MMD 981023]: [ No computer programs exist yet which can convert a MIDI file [ with MIDI "velocity" (such as recorded by a Disklavier) into [ a music roll for a pneumatic reproducing piano. All the codes [ for the pneumatic expression mechanism must be entered manu...

•Hello Folks, I write to you from Canada's fair capitol city of Ottawa, where I am currently on tour with the Stratford Festival, at the National Arts Centre until November 29. What a treat to start my day with the Digest. But darn these notebook keyboards ;-) This thread about the destined-to-crack...

•Install Disklavier Mechanism in Non-Yamaha Pianos! It is no longer necessary to be stuck with a Yamaha brand piano if you wish to own a Disklavier. We can transplant the solenoids from a Disklavier stack into a new, heavily built, high-quality stack rail designed by me, which is covered by my paten...

•Regarding methods of preventing hot glue from getting into the passage to the ball bleed on Ampico "B" valves: there is an easy way, which I learned after many problems: After mating the halves of the bleed and applying pressure, pull them apart again and spin the tip of a cotton swab over the hole...

•For the past year I have been working on the development of an optical scanner for transcribing piano rolls. I began communicating with Richard Stibbons a while ago, and from that time on progress has been steady and at times remarkable. Richard has developed software for receiving the output from ...

•Greetings MMDers, I have been reading and contributing (a little) to the MMD for over a year now and I suppose that I should introduce myself. In the early 70's I studied music in college and built two harpsichords while looking into the pipe organ field. In 1974 I was in the right place at the rig...

•A comment of mine in yesterday's MMD posting needs correcting. Wayne Stahnke's WEB files were said to be proprietary. Fortunately for the music roll community as a whole, that turns out to be a false assumption on my part. Although I've been using Wayne's reading services to have Ampico rolls scann...

•Several people have commented and expressed doubts about the overall performance of round valve replacements in Duo-Arts with cross valves. I understand their concerns, so I decided to post an example of the repetition and dynamics of round valves in a 1923 Steinway Duo-Art on my web page for a sho...

•With great interest I followed the discussion concerning the activities of Paul Lehrman, with whom I am in contact since several months. The project he plans is not as new as it seems to be. Several years ago we performed the Ballet Mecanique with two Ampico player pianos, two pianists, a percussio...

•-- non-subscriber, please reply to sender and MMD -- Recently I was able to locate, borrow, and transcribe all seven of the special rolls that the Ampico company issued for Christmas, 1923-1927. Most of these have the year of issue printed conspicuously on the roll label and box, but the early ones...

•The MIDI wireline, which connects a computer to an external synthesizer (or orchestrion), supports 1000 sequential note events per second, so a chord of 30 notes takes 33 milliseconds (ms) to send. To put this in context, the pneumatic or solenoid player action in the instrument adds anywhere from ...

•The article written by Douglas Henderson is not describing the limitations of MIDI but the design choices of the various elements that make up a MIDI system. A MIDI system consists of the MIDI protocol, the transport and the sound generator. The MIDI protocol is very robust and largely unchanged fr...

•With all of us talking about pumps, let me mention motors: ** Every time you restore a reproducing piano, send the motor out to the motor shop for a complete check up. ** There is nothing worse than a Steinway Duo-Art that has a large round burned hole through the soundboard. This happens! Take no ...

•Although I have been reading the MM Digest for many months, and I have contacted several contributors directly, I have not actually introduced myself because I was not sure where to start. I am something of a Jack of All Trades and Master of None. Anyway, here is my introduction. I am David Sharpe...

•I may have mentioned in past postings about the effort I have put into building roll readers in order to end up with MIDI files. I have built two units, the first of which is being operated by my good friend, Frank Himpsl, who is a musical guru and a great modern ragtime composer as well. This unit...

•Hi All, Regarding Spencer Chase's question about accelerating the tempo of MIDI files and BAR/ANN files to reflect the typical 'real-time' operation of a popular music roll being played on a well-restored regular player piano, my opinion is that the MIDI files and BAR/ANN files should be "error fre...

•Regarding the bleed control screws in the Licensee mentioned by John McClelland [001201 MMD]: Jim Miller, one of the world's great scholars on the subject of the Welte and other reproducing pianos (if also one of the least appreciated), explained to me the importance of correct bleed regulation in ...

•I'm rebuilding a 1931 Knabe Ampico B, and have come across a concern regarding the governor resistor (the resistor in the drawer, by the roll-drive motor, not the large resistor under the piano). The 1929 manual says that the resistance should be 360 ohms. I'm getting a reading of 200 ohms on my oh...
