I've been guest viewing the Forum for a couple of years and own a Johannus LiVE 3TA (the 'A' stands for AGO standard pedal board).

First, thank you for all the good posts--they have greatly expanded my understanding of pipe organs and DOs.

I am about to use the Johannus Intonat software to adjust tuning parameters but would like your ideas about Celeste tuning.

In the unadjusted Cavaille-Coll Notre Dame D'Autil samplest, the Viole de Gambe 8' and Voix Celeste 8' behave in a puzzling manner. Pressing a key one hears a beat frequency difference of ~4 BPM and then pressing the same key a few seconds later one hears a beat frequency of ~8 BPM and press a few seconds later there is no discernible pitch difference. Sometimes the difference doesn't sound like a Celeste but sounds like just out of tune pipes.

The Intonat 7 User Manual parameter "Rank Setting" is used to send "pipeLIFE random detuning". I've been told this the parameter to change.

To avoid the wildly variable Celeste tuning, would it be better to:
1) Reduce the Voix Celeste 8' random detuning to zero--there would be random variation but never as wide as to sound like just out of tune pipes.
2) Reduce both the Viole de Gamba 8' and Voix Celeste 8' random detuning to zero--their pitch differences would be the constant set in the default, and the non-varying Viole de Gamba 8' would still differ when used with other ranks because the other ranks are randomly detuned.
3) Quit fiddling around and go practice more

Again, thank you for posts past, present, and future.

Vielen Dank Uwe

Mein Deutschstudium war vor 40 Jahren zweiklassig. Aufgrund meines schwachen und vage erinnerten Deutsch werde ich Google Translate für kurze, nicht-technische Postings verwenden*.

Unfortunately I will need to use English for DO technical postings as Google Translate isn't fully able to make useful translations--I may learn enough German before Google gets much better : )

Die Intonat-Software von Johannus ermöglicht es, einen Computer (in meinem Fall einen PC) mit dem LiVE 3TA zu verbinden und die Parameter eines einzelnen Samplesets zu modifizieren.

In der kommenden Woche werde ich die beiden oben genannten Ansätze ausprobieren und hoffentlich nichts durcheinander bringen ... Ich werde posten, wenn ich es nicht durcheinander bringe.

Cheers,
Jeff

*Es leistet auf folgende Weise eine angemessene Arbeit für kurze und allgemeine Texte. Ich schreibe den Beitrag auf Englisch, lasse ihn von Google ins Deutsche übersetzen, lasse Google das Deutsche wieder ins Englische übersetzen, bearbeite das ursprüngliche Englisch und wiederhole, bis der größte Teil der Dummheit der automatischen Übersetzung minimiert ist.

Thanks for the guidance on translation AND I'll use DeepL when needed.

Uwe,

You are correct that the LiVE installation calibration is done by the Johannus representative with a specific microphone matched to a laptop with calibration software.

However, the Intonat software does work with LiVE series but is more limited (I believe) than with the other Johannus organ lines/brands.

From the Intonat 7 User Manual, the following image is the table of contents of the LiVE parameters that can be changed on "organ voices" or stops/ranks:

The item 4.9 Rank Settings is where the "pipeLIFE random detuning" parameter is changed.

I don't know how or if the Intonat software works with Nobilis instruments but your representative should.

Finally getting some autumn weather this weekend in Southern California (today it was 32.2° C/90° F),

PS I just realized in my original post I used BPM (beats per minute) but meant BPS (beats per second).
