Organteq on Lowrey

I'm thrilled it worked!  I'm also glad to know that a Microsoft Surface can handle Organteq. (I'm usually at a desktop but having a portable organ "extension" on a small and light laptop is a great idea to try once!)

I also think your idea to simply change MIDI mapping within Organteq was also really wise: my experience with organ consoles and MIDI has taught me that if you can do it without changing anything, do it without changing anything.

I need to try Organteq on larger speakers with a subwoofer.  I'm very curious how it feels and sounds in a larger environment (I bet it does really well).  By the same token, I should try Pianoteq in a large hall too once.

A 32 'pipe necessarily has more inertia than a bass guitar string, but we have all the same, just in France more than 165 instruments with such pipes, (see http://orgue.free.fr/32.html).
That said, wonderful organists have chosen to record on instruments limited to 16 ' pipes.
(see work for complete organ JS Bach by André Isoir, on the Grenzing Organ of the abbey church of Saint Cyprien in Perigord (France)
It should however be noted that even in this example, it is important to reproduce well the resonance frequencies of the church, which ultimately acts as a resonance box for the instrument.
In this example, these resonances start well below 10hz, with notable peaks between 12 and 40hz.
They justify (in my opinion) fully (at home) the use of very low down speakers,
- On the condition of benefiting from (outside) distant neighbors and (at home) understanding relatives ...
The tactile effect of these very low frequencies (unfortunately unavailable with headphones) largely contributes to the atmosphere provided by this instrument.
- ideally, not to be underestimated in future developments of organteq ...

On speakers, I did in recent days with Organteq a test with old hi-fi equipment very heteroclyte downstream of my DAC Aun S6.
I used all around my Casio GP500 keyboard, simultaneously the following 3 systems: (all the speakers being placed less than 80cm from the player, to benefit from a proximity effect).
** Yahama A-500 amplifier 2x85w rms on 2 Triangle Maestro ES speakers, 2 Bass-reflex channels (including 16cm boomer) 91db / 1w / 1m (55-20000hz +/- 3db) +
on sub output, Bass box Triangle Meteor 0.5 bass reflex speaker of 28cm on dedicated amplifier of 300w rms (28-160hz +/- 3db)
** Pioneer A-119 amplifier 2x30w rms on 2 "vintage" Cabasse Sloop M4 speakers (output 94db / w / m) 3-way with 30cm boomers unfortunately for bass, in closed box. (60-20000hz +/- 3db)
** Sony 2x70w rms digital amplifier (CMT-HX70BTR) 2-way bass reflex with 13cm fiberglass boomers +
   MartinLogan Grotto-i bass-reflex bass box (25.4cm boomer) on dedicated 300w rms amplifier (22-120hz +/- 3db)
NB: a second MartinLogan Grotto-i subwoofer (with its dedicated 300w rms amp) will soon reinforce these basses a little.
A Behringer parametric ultra curve equalizer, installed on the Yahama amplifier is not yet configured
to try to balance these heterogeneous sound sources a little better.
Below 28hz, the sound level drops here too quickly (compared to a good headset) and with a significantly higher level of distortion.
(tested on a DAW organteq 1.0 with pipe organs from the Halion 4 library, only below 32hz notes, because organteq is much better)
The interest of the fundamentals of notes lower than 32hz is naturally mainly tactile, contributing to the atmosphere of a church or a cathedral.
Very low frequencies of resonances of the building (for example 7hz, 13 and 19hz) in Saint Sernin are also interesting to reproduce this atmosphere,
with the proviso of not generating the higher resonances and parasitic frequencies which one unfortunately unfortunately easily meets in an ordinary room ...
I think that a box with a driver of 38 to 48 cm in a well tuned column would be ideally preferable compared to my current old equipment
(in the absence of drivers of 80 cm in diameter "more" bulky and very expensive, although much less than a cathedral and its acoustic organ) ...

Gilles, for the 16 'stops limit you are certainly right for the baroque music (which I also particularly appreciate).
Interesting also this remark of impact of the differences of religious cults on the scale of the instruments.

The 32 'stops will effectively generate a very low frequency fundamental which is difficult to reproduce with clean sound using standard audio equipment. (headphones as speaker). My current MartinLogan grotto i sub is also servo controlled (unlike the Triangle sub which will probably be discontinued next week with a second sub grotto i) After further testing this evening, I identified the sound level not to be exceeded to avoid too audible distortion below 40hz. At this too low level, it will not be possible (even with 2 grotto i or equivalent sub) to produce a sound level (mainly tactile objective) comparable to the resonances of a real organ in interaction with the structure of the building. a church or a cathedral below 18hz (even soon with almost 1300w rms in a music room of 35m2), you are probably also right about the current impossibility of simulating the tactile impression of a great volume of  (non virtual) air in a small room, too bad ...

Thus, virtual stops of 32 ' (and even 16') can therefore only be partially appreciated (for the interaction of harmonics) with unfortunatly , at home, a feel like "reduction" of the fundamentale sound level / tactile level, compared to a real acoustic instrument)

(The adjustment of the bass is of course here very approximate and deliberately caricatural.)

Thank you Gilles for this recording.

With this Saturn by the composer Holst // Montreal symphonic orchestra Charles Dutoit // that I did not know before, it is not good to age ...

It seems indeed difficult that the organ used comes from the church of St Eustache in Quebec: https://www.musiqueorguequebec.ca/orgue...ache.html, it "maybe" could have come from the new organ (1989) St Eustache in Paris with its 8000 pipes including several 32 ' pipes: https://www.musiqueorguequebec.ca/orgue...ml#English however, there is at least one passage (at 8' 4 " ) where a clear resonance at 8hz can make imagine a pipe of 64 '. (even if it is more probably a resonance of the structure of the building). More certainly, here the recording of C of fundamental 8hz of the 64 'pipe (actual size) of the organ of the Sydney townhall
link: https://www.sydneyorgan.com/STH64.mp3 naturally much more interesting for its harmonics.

(cf organ spec: http://cdn.sydneytownhall.com.au/media/...s_000.pdf)

In the immediate future, an organ of 8000 pipes in tutti mode would certainly pose to Organteq "some" fan problems,
not for the organ blower, but to cool the many cpu-cores necessary ...
Fortunately, we can have fun with Organteq without thinking as big. ,
even if, in the absence of "Saturn" final C pipes,
going to the configuration of Saint Sernin [=name of a small Saturn: "saturnin" transformed into old southern French] Cavaillé-Coll organ , (for all the types of its stops) , would be, one day ?, for Organteq, a good idea.

In fact it seems to be worse, closer to the pipe,
cf 1rst C (8hz) video on Sydney Contra trombone real 64' wooden pipe: http://www.ohta.org.au/images/STH/64'STH.mp4
(blower problem ? and surely a very bad recording that y tried to remaster a bit in a new ptq mp3 shared file
adding a track with 2 pass of a 120db/octave filter at 12hz to rise lowers fundamental notes + the original non-filtred recording at a lower level)
For Sydney town hall, see also in this picture 32' size above the console: http://www.ohta.org.au/confs/Sydney/Syd...wnHall.jpg
and the organ composition: http://www.ohta.org.au/confs/Sydney/SYD...HALL.html.

For speakers reproduction of lower notes, i will add tomorow a complementary sub (MartinLogan Grotto-i) the same as the 1rst i already get.
With a total of 3 sub so a total of 1629.2 cm2  <=> 45.55cm diam = 17.7 ' speaker (at low level only to limit distortion).
Waiting Modartt build a day ?, a 32' flute stop, i add with a DAW to organteq a Halion 6 organ flute pipe (actived only with a pedal),
in order to add notes from A-2 @ 13.7Hz) to B-1 with my piano keyboard.
NB: it is important to note that human ear can perceive (not only tactil effect) frequency as low as 5hz, if the level is loud enough.

Yes the Atlantic City one is quite a room shaker! I didn't play it too loud in case the neighbors might think there is an earthquake happening but all fundamentals are reproduced by my sub with a peak around 16-20 Hz. I can almost count the cycles looking at the cone moving at 8 Hz...

Also thanks for the explanation for "resultant" pipes. Our recent Casavant organ in Québec's Palais Montcalm is said to have "32' resultant Bass" but I had only seen 16' pipes there.

Wow, tmyoung!  That low bass stuff is crazy!  Makes me think of the times that I have stood across the street from railroad tracks near paper mills in Florida as a General Electric Electro-Motive Diesel engine is doing low-speed pushing and pulling of lines of cars loaded with wet pine logs - slow speed, lots of torque, and chest thumping bass with barely perceptible 'tones'.  My 8" sub connected to my Surface Tablet/Pianoteq/Organteq sound system didn't do it justice, but my shelves shook and my chest vibrated.

By the way, back to the original post idea - I am told that Lowrey is no longer, as of NAMM 2020.  This is heresay to me via my Dad via his distributor-friend.  So, there may be a bunch of Organteq-capable consoles around to pick-up.  :-)
