Temperaments and the Ott-Orgel

[BachsFugue]

This query is directed especially to Martin Dyde.

I downloaded the new files for the Ott-Orgel and used my old samples. I've renamed them and the implementation worked flawlessly. Thanks to all! (8-)

Now, here's the question. If I use my retuned samples (I use the Lehman-New Bach temperament) that I created with Martin Dümig's PipeTune utility, and choose the option for Original Tuning, will it work properly.

Also, when is someone going to have the Lehman-NewBach temperament to add to the already existing temperaments available for Hauptwerk 2? I'd volunteer if I knew how.

Hello Cole,

I'm afraid I've not been able to look at the Ott organ yet because my main PC is tied up testing Hauptwerk v2.01 changes. There is a bug in v2.00 which affects the 'original organ tuning' option: see HW2-000015.

Whether using re-tuned samples would work properly depends on how Reiner has configured the v2 organ definition. However, I expect that it would work if you just used such samples and set Hauptwerk's temperament to 'equal' because Hauptwerk would be deceived into thinking that the samples were already tuned to equal temperament and thus not re-pitch them. However, doing that (i.e. 'cheating' Hauptwerk's pitch specification) would render Hauptwerk's other temperaments incorrect, so I wouldn't recommend it.

A much better solution would be to persuade somebody to make a Lehman-NewBach Hauptwerk temperament file for you. It may be worth contacting Martin Dümig, since I believe he may be working on some additional new temperaments for Hauptwerk.

All the best,
Martin.

Thank you, Martin.

Hello Cole,

I would also think that it should work, since the odf is configured to make HW think the samples are in perfect concert pitch and equal tuning (which the original Ott-samples are). So youre retuned samples should come out untouched. But like Martin says, the preferred way would be a temperament file for HW2 (in which case you would need to use the original samples).
I might be able to generate such a file if you could mail me the exact tuning specification, but it will take a few days before I'll get to have a look at it.

Best wishes

Hello Cole, hello Reiner,

think i have all necessary data but must do some thinking an computations to convert to the frequency numbers used by the temperament-files of HW2. Will send you my proposal this evening.

The description with the cent-deviation could be found on:

Hi Martin,

thanks for the link. The cents deviation is all I need, I do have a little program to compute all the pitches required. I'll see if I get to make an xml-file for the temperament tonight.

Best wishes

I was going to try running pitch detection on an already retuned file and make an XML file from those figures, put your approach will be much more accurate. I hope the file will be shared publicly, since Bradley has not put on any restrictions on his "intellectual property" that I know of.

I have already generated the tuning file. Just to be sure I will wait for an ok from Dr. Lehman and I also asked him what the 'official' name for the tuning should be. Once I have his ok, I will post it for public download on my website.

Best wishes

Hello Reiner,

very good to inform Dr. Lehman for his ok. I would include a link to the webpages of Dr. Lehman (www.larips.com) in the comment-tag of the temperament file for reference.

Thank you - and i will test the file as soon as available on your webpage.

With best regards - Martin Dümig

Thank you to all!
