    GPO Organ sample question

    ok, I'm looking at all the organ sounds included with GPO, and I find it fascinating.
    I've never written for the organ, but being a relatively accomplished pianist, I figure it could be an interesting challenge.

    I've fiddled around on the organ in our school's chapel when I was a kid, but not really enough to understand how all the buttons and knobbies work.

    I understand that "stops" are different instrument sounds.
    I understand that you can give different combinations of sounds to each manual and to the pedals.

    However, the NAMES in GPO kind fo confuse me.
    They definatley don't match any of the names that were written on our school's instrument, other than "flute" and "cornet".

    So, how exactly do I go about mixing and matching the various samples in GPO to get a good idea of writing for organ?

    what exactly is a "plenum"? is that a specific type of stop?

    what is the difference between "Baroque plenum" and "Baroque plenum reeds"?

    What exactly is a "Haupt Mix"?
    Is that in any way related to the "Hauptwerk All Stops"?

    What is a "Brustwerk all stops"?

    Are these ALL sounds that I can more or less expect to find on an organ?

    If not, is there any way I could rename them to something a bit more standard? (even if it's just a list on paper, like "Haupt. mix = blah blah blah" or something)

    I would GREATLY appreciate a bit of a tutorial on this.

    I am slowly working on putting together some Finale'08 tutorials for using HumanPlayback, GPO and Finale to both publish your score AND get it to playback nicely.

    Stefan threw out some information a couple of days ago here.

    yeah, that's not quite the information I'm looking for.

    Plenum = Principal chorus, mixtures and often reeds (not always though).

    Baroque plenum = Plenum without reeds

    Baroque plenum reeds = Plenum with reeds

    Haupt mix = Plenum on hauptwerk (manual 1, great) without reeds

    Hauptwerk all stops = All stops on hauptwerk, including reeds etc.

    Brustwerk all stops = All stops on brustwerk (manual 3, choir)


    These are just combinations of many stops, but you will have thousand more possibilities if you could choice individual stops yourself.

    Re: GPO Organ sample question

    ok, WHAT are "Hauptwerk" and "Scharf" and "Brustwerk"?
    are they specific organs?
    types of tubes/stops?

    all the different samples included in GPO, would one find them all on the same organ? or are they from different and "contradictory" organs?

    why "Scharf IV"? what happened to Scharfs one through three?
    and what is a "prinzipal"?

    Hauptwerk and Brustwerk are manuals (keyboards), each manual has it own set of stops. The Hauptwerk has the most powerful stops (in general) and most stops, Swell is weaker and has 2nd most stops, brustwerk has more solo stops but overall fewer stops than Swell and it hasn't expression pedal like Swell has.

    Scharf is a name of a stop which is a mixture and the roman numerals mean how many pipes sound together on every note you play. So when you hit C, then you will hear a mixture of 4 pipes.
    For more info on stops see http://www.organstops.org/

    GPO organ is I think sampled from one organ.

    Prinzipal (English: Principal) is for organ like the string section for symphony orchestra, it's the most important stop of the organ and it's in every organ.
    Principal choir is set of principal stops pulled out together.

    Every stop is marked with foot, so following means:

    64' = 3 octaves below written note
    32' = 2 octaves below written note
    16' = 1 octave below written note
    8' = sounds as written
    4' = 1 octave above written note
    2' = 2 octaves above written note
    1' = 3 octaves above written note
