Allen Tone Cards Needed

[myorgan]

Does anyone have any of the following tone cards for an MOS instrument for sale or trade (Bold especially needed)? I prefer plastic/newer cards, if you have them.</P>
<UL>
<LI>Chrysoglott</LI>
<LI>Trumpet A 8'</LI>
<LI>Tubular Chimes</LI>
<LI>Stereo Glock</LI>
<LI>Orch Oboe A 8'</LI>
<LI>Rhorflöte A 8'</LI>
<LI>Flemish Bells</LI>
<LI>Music Box</LI>[/list]


Thanks in advance for any help any of y'all can give.</P>

Re: Allen Tone Cards Needed



I'm guessing that the "A, B, C" refers to different tonalities under the same name (to provide some variety, I expect).</P>


I have a manual card punch and could possibly duplicate an existing card if I were sent a picture of it (put a dark sheet under the card so the holes show clearly). I also have a tool that can give instructions on how to punch a card to get a particular set of harmonics. (I think Al already has it.)</P>


Al, you never said whether or not you were able to find a card punch--did you?</P>

Al,</P>


From what I've seen on the cards I've purchased (I have several with 3 different letter designations), the letter simply was added to delineate a change/improvement in the stop's configuration. This could beanything from the amplitude being changed (louder/softer), or a particular partial of the overtone series being accentuated or reigned in a little. The changes are there, but to the non-organist would probably be imperceptible other than a general feeling of hearing a pleasant vs. un-pleasant sound.</P>


Hope this helps.</P>


I've e-mailed you privately.</P>

You are correct. The cards are simply variations of the original sound. In the early MOS days, Allen produced the digital waveforms by analyzing the harmonic content of organ pipes. Then taking that data, they would program a waveform with 24 harmonics to imitate the sound. Strickly speaking, it was not sampling, but resynthesis. The third generation of card systems were nothing more than a switch to tell the organ to use an existing sample hidden in the organ's memory. It could have its loudness controlled by codes on the card. So there might be more than one card for the same stop that simply changed the loudness.</P>


The last time I checked, Allen was still selling all three card libraries on their site.</P>

Re: Allen Tone Cards Needed



I just received some information from the Allen Organ Company.</P>


Turns out, the letter designation can be anything from volume, tone variation, or harmonic structure. There is no set scheme. I also learned that for the Mixtures, they have a designation whether they should be used with Reed or Flue pipes. Further, I learned that some cards require 2-3 cards in combination to "build" a particular stop (i.e. Harp).</P>


The "Tone Card Library Order Form" is copyrighted (1981), so I cannot send out copies (although, I have put it on my computer). However, if anyone needs some particular information, I can see no reason why I should not share that.</P>


They also list some other sources:</P>
<UL>
<LI>Vincent E. Slater of 4815 Tacoma Avenue, Fort Wayne, IN 46807, has published a booklet entitled "Guide to Organ Stops," which catalogues the Allen Organ tone cards. The document encourages people to contact him directly.</LI>
<LI>Audsley's Organ Stops and their Artistic Registration</LI>
<LI>Allen Organ Two-Manual Registration Coruse by Sally Cherrington, and</LI>
<LI>Organ Registration by E. Harold Geer, J. Fisher &amp; Bros., Glenrock NJ.</LI>[/list]


If anyone needs information in particular regarding one of the cards on the MOS organ, I'd be glad to provide it. Thanks for your help in getting this information too.</P>
