I have a Galanti Praeludium/Gem Studium (not sure why it has two names!) and was trying to hook it up to Hauptwerk via MIDI. Does anyone have a MIDI spec for this organ? I can get the manuals and pedals working but the expression pedal and tabs don't. It's possible they're not MIDI-fied but it's also possible that I'm missing something!</p>
It'd be nice to know what all the knobs on the underside of the organ do, too (though I've worked out 'Master Volume' :o))</p>
In short I need a manual, or someone who knows this organ.</p>
I think the reason for the 2 names, is that in Europe this model was called a Studium, in North America it was the Praeludium 1. It was the smaller of the 2 manual organs they made in the late 80s and into the early 90s.</p>
Because this was an early digital organ with MIDI (this was designed when MIDI was still in it's infancy, only the keyboards and pedalboard puts out MIDI. Stops and expression have no MIDI.</p>
If I remember correctly, there are 2 panels under the keydesk. On the one side there is the master volume, pipe noise control, tremolo speed and tremolo depth plus some audio in and outs.</p>
On the other side there is the MIDI in and out. Plus there is an ensemble switch (think alternate tuning swtich), Chiff A/B (loud and soft chiff on some flue stops), keyboard inverse (you can set the swell to be the lower keyboard, and great the upper), and there is a knob to adjust overall pitch of organ. </p>
You won't need a manual now. I have told you everything in it. I have the manual somewhere, but wouldn't know where to find it.</p>
I have a similar model organ and the description is correct. I'd be interested in knowing if the midi sounds can be assigned a specific manual. Right now the same ssamples play on both manuals and pedal. I have aon old Yahah sound expander that came with the instrument. Would a sound source with assignable channels/midi allow me to assign to different manuals? Novice here on midi, so be kind
That's great AV, thanks. I wondered what 'p.n.c' was - seems so obvious now! It's a bit of a drag that the stops aren't MIDI but I got the organ cheaply, so I shouldn't complain. </p>
Ludwig - yes, if you assign different channels on your sound module (I think you'd have to be in some kind of multitimbral mode) you'd be able to do what you want.</p>
Hello.
Arie yes, you are right. In Europe, the organ is called Studium.
Was part of a series of electronic organs with the primary sampling.
In Europe, there were four models: Chorus III (small organ with two
manuals and 30 keys ped.), Studium, Plenum (similar to studium but morestops and toe pistons), Concerto (three keyboards).
I am not sure
about whether the stops have the midi control, but I am sure that the shoe swells (crescendo and swell expression) and hand/toe piston
certainly have midi.
Some time ago I connected a ahborn expander
202 to a Gem concerto. The organ was able to perfectly control the
expression, the crescendo and combinaction of expander.</p>
You are correct as far as the Concerto goes. In North America it was called the Praeludium III. The Concerto was a somewhat later model, as it came to market in 1989. The Plenum and Studium designs came out in 1986. By 1989 MIDI protocol was more sorted out, and the idea of MIDI doing expander as well as sequencing functions was being implemented in organs. </p>
I service at least 4 of these Praeludium III organs. I kinda know what makes them tick. I service quite a number of Praeludium I and Praeludium II organs as well. The Praeludium III is a different organ as far as the electronic architecture goes. Believe it or not, the Praeludium III had 16 audio outputs. I never saw one with more than 8, 2 of them used only 2 audio outs. The Praeludium III when properly setup was a very decent sounding organ.</p>
I have also seen the audio outputs. It is 16 and I was surprised. In fact in the 80s, this was rare. </p>Perhaps that Präludium III then has a different midi implementation.
I have three friends who have a Gem concerto, they still work perfectly.
We need to clean keyboards contact, why have the open contacts and it may happen that some key does not work correctly.
The Crescendo swell sometimes remains active, we must insist on the pedal
to turn it off. This is a problem common to all of my three friends.
The organ sounds very good;; apart from this small problem, never had a repair in 20 years of use!</p>
Re: the Crescendo pedal. There are crescendo pedal adjustments available on the lower interface board in the organ. I believe that is how that board is labelled. Anyways, there is a minimum and a maximum adjustment via potentiometers. The maximum adjustment is R47, the minimum adjustment is R44. If I remember correctly, the 2 are somewhat interactive. Doing the adjustments carefully gives you an idea of how they work.</p>
Yes, about the keyboard contacts, they were a problem at least on some organs. </p>
Well, for 1989, the Concerto was among the very best sounding electronic organs, at least of those made in Europe. </p>
Unfortunately, in North America most dealers just sold them on the cheap, put 2 or 4 audio channels on them, collected the cheque and walked off. With more audio channels and some creative parts swapping, they could really have been much better balanced tonally. I guess I just see organs differently from most manufacturers and dealers. I believe they should be an artistic effort as well as be musical (or at least as best as they can be).</p>
AV</p>
P.S. If you get into one of these, you may want to check on the 3.6 V ni-cad battery, which holds up the piston settings of the organ. If it is still original, the battery will need replacing by now.</p>
