•Hi Dale, The one 'T' connector you referred to in your article sounds like the connection from the push button "Loud" control in front of the keys to the Auto-Sustain device in the lower left hand corner of the unit. The other 'mystery' connection goes to the 'On-Off' switch in the spoolbox, in the...

•Hi I am happy to report that our roll recording step piano is now working perfectly. I am in need of one more a device to finish it. I am looking for a simple Led or LCD counter that will "count" the pedal presses as I advance the clock. This can be a simple three or four digit counter that "counts...

•Having lurked around MMD in silence for a couple of years (and learned a lot), I can't resist raising a small voice on the subject of the Sankyo 20-note player punch-a-tune. I believe this device made its first appearance in America twenty or thirty years ago, when a battery-powered version was mar...

•Hi again, more pling-plong information. In response to various questions I have received about the pling-plong device, which plays self-punched paper strips, I offer the following: 1. The device is indeed made by Sankyo, but I have heard from more than one source that it is not imported into the Un...

•Craig Smith's "This Side Up" story makes a good point. Manufacturers of delicate industrial equipment have solved that problem with a device called "Tip-N-Tell" or some such name. It's a plastic "UP" indicator that fastens to the outside of the box, and it shows clearly which way is up. On its face...

•Headed out the door on vacation last weekend, we listed a pair of Kalliope 176s with cabinet and a dozen disks each. Though we don't generally post much to eBay, these two devices and lots of photos (with movies and sound files) are posted as well. We have a large mechanical music estate about read...

•I woke up this morning with a smile because I realized that I can extend the rotating head thread! Years ago there was an article in AMICA magazine about how Dr. Hickman's piano hammer speed spark measuring device worked. As I recall he used a rotating drum with a spirally wound ground wire with pa...

•A bit more on the recent discussion about single-ear tracking systems. Dan Wilson described how the single-ear systems seen in the UK are fitted with a locking device that prevents any tracking action in rewind. This uses a sprung pneumatic, powered from the stack supply so that the lock is removed...

•Hi! I'm a new member in France, and I've joined MMD because I've MIDI-fied my player piano with a device of my own. I'm a retired engineer, and I have been interested in pipe organs since I was a child. My job was related to computers, and my hobbies concern musical electronics and microprocessors ...

•Hello, I am looking for information about an "Artisan Bandbox" made in Altadena, California. I need a service manual and some parts. If you know of anyone who might know about this device, please pass this note and photo along. Any help would be appreciated. Thanks, Tony Leo - San Francisco - 650-3...

•Hi Folks, Does anybody know the intended use for the large hole on the left side of a Schulz tracker bar? This is the version of the Schulz with the swinging arm centering device. On the left side of the spool box is a 'Loud Pedal' on/off switch label. The switch is missing and there is nothing con...

•Hi Matthew, Your post in 000528 MMDigest about the Seabreeze tune cards and the nostalgia about Ross Davis tune indicator board brought back some interesting memories. I thought you might be interested in my personal remembrances on that device(s). I presume you never saw it in person. There were a...

•Yes, Bob, The 33.3-divided-by-two-speed was very useful to slow down music; but to then play an octave high took a good ear. Now I have a device called Voice-it, which has a double speed and half speed playback, which does not change the frequency. 10 years ago such dictation aids were available, b...

•I didn't quite understand what exactly the "Piano Horse" is. Is it some kind of skid board? I had a device by the same name. It was a folding tripod made of 2 X 4's and held up one corner of the grand to allow for the first leg to come off and on for moving. By the way, two people can move most gra...

•Hello again, I have a slightly different problem using Cakewalk. I want to use it to 'record' music from a barrel organ or similar device using switch closures to pick up each note. I can get it to do the recording but I still have 2 problems. 1 - I can't see what is being recorded (or even IF it i...

•Hi there! A few days ago I found an incomplete action of a (I think) Hupfeld Triphonola. It belonged to a Roenisch piano that was sold without the player mechanism. I have the complete stack, 'solo' device, pedal pneumatic, motor tempo controller, an extra original box with leather valves, hanging ...

•In response to a growing interest in building roll scanners, I have put together a package of notes, diagrams and software describing my system. The design is the result of several years experimentation and is based on a contact image sensor device as used in 'state of the art' fax machines. The sy...
