•I'm in the process of converting my Aeolian player to Duo-Art, and I have just finished restoring the expression box, with one minor modification. I have not included a device, which seems to be an original part, which prevents the accordions from closing fully thus softening the play. Since the ex...

•I recommend keeping the softening device for your Duo-Art. I would even recommend putting it back in place. It is a little in the way, but you never need to use it. If it is the deluxe model with the pneumatic to operate it, you needn't recover the pneumatic unless you are concerned with appearance...

•Ampico B owners are well aware that some "A" coded rolls don't sound very good on the "B". The performance can fall flat, sounding at half volume when full fortissimo is required. I've grappled with that dilemma for years. Since I am a student of Ampico coding, and understand the cause of this shor...

•Development continues on my invention that will aid in better performance of Ampico A rolls played on the Ampico B. The deficiency of the B piano to properly play some A coded rolls was known by Dr. Hickman before the first B piano was sold. In attempting to avoid those issues of incompatibility, A...

•(This was posted in Facebook Player Piano Talk also, but posted here for those interested but not in that forum.) Bob Taylor's YouTube video of his Ampico A roll compatibility device for the B is quite interesting. [ https://www.youtube.com/watch?v=ZyFrUQz6KM4 [ At time 1:55, "Same except with logi...

•As I previously announced, I have developed an attachment for the Ampico B piano that improves the performance of "A" coded rolls. Testing continues on this device. The proof of concept is complete and now refinements are taking place. Initially, I planned on equipping the device with some type of ...

•Hi All, I've followed this thread fairly closely and I've had the same nagging question from the beginning. Considering how fast the events in a reproducing music roll occur and the amount of time it takes any valve to cycle, won't the addition of a valve, in line with the expression system, disrup...

•Hi all, I have tested, on four different Model B Ampico pianos, Robert W. Taylor's A/B translator device to make Ampico A rolls sound as if they are playing on an A piano rather than a Model B. Three of the pianos belong to Doug Miller; they are (1) the 7' Mason Hamlin that came from the Ampico lab...

•Hi All, Sorry, I did not have time to complete all the information the first time about Robert Taylor's A/B translator [171002 MMDigest]. It comes with detailed installation instructions, with color prints of the locations of the tubing attachments needed to install the device. I think that anyone ...

•During the summer of 1982 I was playing the piano at the Blue Angel Cafe in Charleston, S.C. At that time I met a local piano tuner named Walter Mudgett. I visited his home where he displayed a rebuilt Hardman & Peck upright which had a very ornate cabinet which he had painted black. It was complet...

•I am toying with the idea of editing some 88-note new QRS rolls with simple registration for my Reproduco and wondered if anyone had a good idea for a device to accomplish this. I'm thinking along the lines of an old spoolbox modified or open for ideas. I would also like to be able to re-spool larg...

•Here are some photos of an accumulator I found in my parts bin. If anyone has an idea about its musical application or the musical instrument it came from, I'd like to hear about it. It is decently constructed, mostly of wood. Two pneumatics (which still work weakly) move the toothed disc this way ...

•Ref. https://www.mmdigest.com/Archives/Digests/202002/2020.02.24.04.html The device that Tom Sendall posted [in 200224 MMDigest] is a coin accumulator for a Seeburg nickelodeon. One identical to it is in my Seeburg L. Bruce Clark

•Hello -- The device I posted on MMDigest on 2020.02.24 was identified through the photos as a Wurlitzer coin accumulator (or counter) by our readers. I passed it on to an MMDer who felt that he could make use of it. Tom Sendall [ MMDigest articles about this device are indexed at [ https://www.mmdi...

•[ Ref. Tom Sendall in 200224 MMD ] Tom Sendall had a Seeburg accumulator that is very desirable. It was not a Wurlitzer accumulator. Don Teach Shreveport, Louisiana

•I think Dave Saul (the AMICA Technicalities Editor many years ago) once showed me a sketch of this device. My recollection is that the pneumatic porportionately _opposed_ the action of the small expression pneumatics (2,4,6), and the result is compression of the output stack pressures. The "Loud" m...

Pete Docter asked if player pianos and animatronics are the same thing. I would say yes and no. However, in the Deuches Museum in Munich, Germany resides the "remains" of an animatronics trumpeteer whose only movement was that of the umbuchre of his leather covered lips while blowing a valveless tru...

•Greetings all, In the 7/26 MMD, Gary Rasmussen mentioned that he was working on a device consisting of a set of miniature electric valves that would fit on a tracker bar in place of a roll and allow operation of the instrument from a MIDI device. I am interested in the possibilities of such a unit ...

•In a message dated 97-07-31 01:15:09 EDT, you write: > Subject: Tracker Bar Device (Bob Ricco) Thank you for for listing my question involving wanting standards or tolerances to the dimension of tracker bars. I received several responses. No one seems to know anything about what was agreed to in ap...

•Hopefully, someone will be able to try this roll reading machine from Ragtime Automatic Music and give us an unbiased report on it. However, I think that Ken Caulkins should definitely plan on attending the MBSI convention in Charlotte, NC in September of '98 and set up his equipment for an honest ...
