•Yesterday Mr. Toto suggested that the Hagen-Poiseuille law could be used to calculate the relative flows between player piano bleeds of differing sizes. This law can be reduced to the conclusion that the ratio of flow between two different flow conduits is proportional to the ratio of the fourth po...

•Andy, Here's the information I collected when I was shopping for a small organ. 1. Alan Pell in England builds a variety of sizes. I've never found a web site for him, but Angelo Rulli is the North American distributor and he does have a web site. [ http://home.earthlink.net/~musicgrinder/index.htm...

•Just thought the MMD readers might be interested. I think that it is amazing that such an instrument has laid unknown for so many years. You never know perhaps a No 10 or a large Helios might turn up next! Let's hope that this instrument stays within the UK and doesn't end up in the States or Japan...

•Wurlitzer did make, or have made, a few roll changers for their residence organs. They never really got into the residence organ field anywhere like Aeolian or Welte. To establish this particular player, if it is indeed a Wurlitzer product and not some other player that someone grafted onto the org...

•Just an update to let everyone know that two more CD's of Welte piano rolls are planned by Ken Caswell. Albany Distributors will be offering his digitally recorded CD of all the piano rolls Enrique Granados made for Welte. The CD will be available in early November. Later, in December, Albany will ...

•Hello all, I totally agree with the sentiments expressed in the letter raising issues related to the ethics of certain fair organ restorations that was originally published in 'Worlds Fair', and am pleased that a number of respected organ builders have chosen to publicly speak out on the issue. In ...

•Hi Craig, Nothing makes me madder that a software company that thinks they know, better that I, what I want on my computer. Hence, my attempt to help you with your RealPlayer problem. First of all, (I am using Windows 98) use "Find", "Files or Folders" at the "Start" menu to locate a file called "m...

•Hi all, After a minor computer problem, my Cakewalk Professional 7 required reinstalling from disc. Unfortunately I had no such disc, having borrowed the program from a very generous fellow MMDer. (Thanks, Phil) I had balked at purchasing the expensive Cakewalk Professional because I use it only fo...

•I have been reading the various thoughts on this with great interest and a little amazement. The one opinion (by Nicholas Simons) that I have to comment on is: > The fitting of a MIDI system to any old instrument, even in a > non-destructive manner, is not acceptable. One argument to be heard, > pa...

•I wonder if any of you might have recordings of 89+ key VB [Violin-Baritone] scale Gavioli or Marenghi organs that are in a relatively un-muddled state (the organ, that is) that you might be willing to share? I've asked around a lot and so far am not aware of commercial recordings of decent sound q...

•Great Dorset Steam Fair - First Time Visitor Report Many months ago, I asked MMD readers a number of questions that would help me plan a visit and help with logistics for my planned first time visit to the Great Dorset Steam Fair (GDSF) in Dorset, England. Although I had done independent research, ...

•The recent postings about the Great Dorset Steam Fair have prompted me to finally send something in on another steam & organ rally worthy of your attention, the Lincolnshire Steam and Vintage rally, which was held August 20-21 at the beautiful agricultural exhibition grounds near Lincoln. I've post...

•Selling to collectors abroad and historic context of instruments. Following my last posting it has been interesting that I have received a large number of emails agreeing with my stance but none have been posted on the MMD, is that they fear upsetting people. I think from their comments that many p...

•[ Ref. "Wurlitzer Console Piano with Pneumatic Reproducer" in [ 060819 MMDigest. Hi All, The Wurlitzer Electro Pneumatic Player, Model 1402, was produced in the very early 1970's. The "Player Piano Schematic" in the Model 1402 Service Manual is dated July 1, 1970. The '1402' had a 98-hole trackerba...

•Julie Porter noted that the offset drum holes on the Wurlitzer 165 tracker bar are different holes than on the APP and Caliola tracker bar, and that the Wurlitzer 165 at Glen Echo Park, Maryland, has Caliola tracker bars. The Glen Echo 165 has Caliola bars because it was converted to Caliola rolls...

•[ Ref. 170605 MMDigest and [ http://www.mmdigest.com/Attachments/17/06/05/170605_170306_AA7512b2.png I'm not sure that the hole positioning is different to the 1/9 inch spacing. If the spacing is 0.111 inch, how much variation would be acceptable? If we assumed 1/10 of the hole spacing as being a s...

•Some years back, here in San Antonio, Texas, a music store who sold the PianoDisc system went out of business and I acquired their _new_ inventory of PianoDisc 3.5" _floppy diskette_ disc media. All of it is still in the jewel cases, some of which have broken hinges, etc., due to plastic fatigue. T...

•My rebuild of my Aeolian Grand organ is nearing completion. It plays now, but requires furious pedaling. I'm busy chasing down leaks, bits of sawdust under valves, pallet valves that only close 98% etc. Because the operating pressure (vacuum in this case) is so low on this machine every tiny bit co...

•Johnny Verbeeck built only one 125-key concert organ. The construction took the full year 1989. It was supplied to Willis Boyd early in 1990. I am sure about this, as I have visited the Verbeeck workshop many times (to supply music) and I was a witness when the 125-key organ was built. In an articl...

In the digest for March 10th, Steve Harder enquired about the musical qualities of a list of Recordo rolls. I have some of them, Steve, and I played them this morning before going to work. Here's what I think about them: #187 En Automne, Moszkowsi Great stuff, passionate playing by Ivan Kerouak #355...
