An overview
The organ cabinetry
The organ cabinet consists of the console shell, music-rack, pedalboard and bench.
Our standard organ cabinet is designed in dark or light oak with solid wood panels.
Your organ may be custom-ordered in another finish, color or wood.
The console
Typically, the console consists of two or three manuals and several accessories.
The keyboards have a church organ touch and are normally designed with synthetic key
surfaces. You may custom-order wooden keys. For more information, read “The console in
detail.”
The music rack
The music rack is typically not yet installed at the time of delivery.
If this is the case when your new organ is a Rembrandt 200 or 300, simply insert the music rack
into the groove provided on the top panel of the organ cabinet.
On the Rembrandt 2000 and 3000 there are two supports left and right. Insert the music rack
with the two wooden pins into the grooves provided. The music rack rests against the front of
the roll-top cover. To close the roll-top cover the music rack has to be turned downwards until
it rests on the side blocks of the keyboards. After that the roll-top cover may be closed.
The roll-top cover
The wooden roll-top cover is provided with a lock and key. The lock is placed behind the music-
rack on the top of the organ.
Open the organ in the following way:
1. Put the key in the lock.
2. Rotate the key a quarter turn; the lock moves upwards.
3. Push the roll-top upwards.
4. In case of the Rembrandt 2000 or 3000, turn up the music rack until it rests against the front
of the roll-top cover.

Lock the organ in the following way:
1. Make certain that you have the key handy (see warning).
2. In case of the Rembrandt 2000 or 3000, turn down the music rack until it rests on the side
blocks of the keyboard.
3. Pull at the roll-top toward you.
4. Push in the cover-lock.
Warning
Youcan lock the organ without using of the key. However, the key is necessary to open the
organ. Therefore, always take care that the key is not left withing the console before depressing
the lock!
The pedalboard
Typically, AGO (American Guild of Organists) organs have a 32-note AGO pedalboard.
The pedalboard is removable. At the front of each pedal key is a magnet. This magnet normally
sits in close proximity to a reed switch, which is invisibly mounted behind the black painted front
panel at the bottom of the console. When you depress a pedal key, the reed switch is activated
by the magnet at the end of the key.
Your new organ has lighting above the pedalboard which is switched on and off automatically
with the organ.
The following points are important for installing the pedal-board:
1. Make sure that the surface under the console in combination with the pedalboard is flat.
2. For the best alignment of the pedal-board, it may be necessary to adjust the console height
slightly while positioning the pedalboard.
3. Shift the pedalboard against the black painted front panel as close as possible.
The organ bench
Your organ is provided with a bench that contains a music shelf. If you wish, you can order an
adjustable-height bench.

Set up
Connecting the organ
pay close attention to the following points when you connect the organ:
1. Check the Main voltage before you connect the organ. This voltage must be the voltage as
printed on the serial numberplate located on the left side under the keyboards.
2. Connect the organ to a grounded outlet. When this is not possible there is a chance some
functions will not always work properly.
Switching on the organ
Switch on the organ by depressing the Main power switch located on the right side of the
keyboards. The red pilot lamp will light up as soon as the organ is switched on. It takes a few
seconds before all controls are working. The computer circuits need this time to initialize.
The display of the organ (located on the right side above the keyboards) will show the following
text:
M e m : 1 V o l : 1 2 T u n e : 4 4 0
T r a ns : 0 C re s c en d o :O f f
Depending on the programmed settings the gray areas may have a different value.
Also the ‘0' thumb pistons will light up.

Every division has its own independent tremulant.
When you use couplers and/or the CF piston the Tremulants will be coupled to the
corresponding keyboards.

User’s Manual Rembrandt 200, 300, 2000 and 3000 AGO
JOHANNUSJOHANNUS

Tremolo
The Tibia Organ stop has it’s own independent tremolo. This special stop belongs to the swell
division (Rembrandt 200/2000 AGO) or to the great division (Rembrandt 300/3000 AGO).
When you use couplers (and/or the CF piston on the Rembrandt 200/2000 AGO) the Tibia
Organ Tremolo will be coupled to the corresponding keyboards.
Chorus
To avoid the organ sounding too sterile, the instrument is designed with various stops tuned
differently,in relation to each other. These small differences give the organ a broader, more
lively character. Switching on this stop will intensify the difference in tuning between the various
voices.
Intonation 2
Intonation determines the sound of the organ. In pipe organ-building the voicing is a very
important part of the building process. Every stop will be adjusted note by note to the room
where the organ is installed.
Standard your organ has two intonations, a romantic and a baroque intonation. In general a
romantic organ is wider and sounds symphonic while a baroque organ is brighter and more
tightly tuned. Also see under “Choice of temperament.”
MIDI-tabs
The programmable MIDI-tabs are a special group of accessories. See under “MIDI applications”
and "Programmable MIDI".
Display
An LCD-display is located on the right side above the keyboards. On the display different
settings are shown like:
!Selected capture memory level (Memory 1 - 8). See “Using the capture system”.

Stops
The organ is equipped with two kinds of stops. The speaking voices are on lighted drawknobs,
while the accessories and all special voices are on tabs. Both kinds of stops are switches that
will come back in their middle position after being switched on or off. In every drawknob or tab
alight will light up when that stop is switched on. These stop lights also work with the use of
presets, free combinations and general crescendo.
On a pipe organ you switch a rank of pipes on or off with the stops. By varying the combinations
of stops the organist can create dynamic- and colorful changes. This means that some
knowledge of the traditional pipe organ is necessary to make good stop combinations. You
should know a little bit about the different sounds of the different organ stops. That is why we
give a brief explanation about these different kinds of organ stops.
In the appendices you’ll find extensive examples of
Organ pipes can be divided in two main groups:
!Flues
!Reeds
Flue pipes
The principle of the tone generation with flue pipes is the same than with a record. Flue pipes
occur in two versions: open or (half) stopped. An example of a half-stopped pipe is the
Rohrflute. On the canister-stopper a small open tube has been soldered. An example of an open
flue pipe is the Principal. Normally the pipes of this stop are located in the facade of a pipe
organ. Flues can be subdivided in the following categories:
Principals
Principals are the Diapason, Octave, Twelfth, Fifteenth, Mixture, Scharff, Cymbel, Rauschpfeife
and Sesquialter. The last 5 stops sound with more than one pipe of different pitch together per
note. So called multi rank stops.
Strings
These are the narrow scaled, open flue pipes like: Viola di gambe, Vox Celeste and Salicet.
Flues
Flute stops, open as well as stopped are made of metal or wood. For example: Hohlflute,
Gedeckt, Bourdon, Subbass, Nazard, Waldflute, Gemshorn and Rohrflute.
Reeds
In a reed pipe the wind is blown into the pipe bringing a reed into resonance. This resonance
is ‘amplified’ and ‘colored’ by a tube (resonator). Reeds with a conical resonator are: Bombarde,
Trumpet,Schalmey, etc. The group of cylindrical resonators are: Fagotto, Cromorne,
Krummhorn etc. The following reeds have a short resonator: Regal, Vox Humana, Ranket.

User’s Manual Rembrandt 200, 300, 2000 and 3000 AGO
JOHANNUSJOHANNUS
12
Special voices
Except the characteristic pipe organ voices, each division also has two special voices.
Although these special voices are no standard pipe organ voices, nevertheless they can be
seen as an enrichment of your organ.
On the Rembrandt 200/2000 AGO, the Strings and the Tibia organ are added to the Swell
division while the Chimes and the Harpsichord can be found on the Great division.
On the Rembrandt 300/3000 AGO, the Strings and the Choir are added to the Swell division,
the Chimes and the Tibia organ to the Great division and the Harpsichord and Harp are added
to the Choir division.
Overview of stops per type
You will find an overview of stops per organ in the appendix under examples of registrations.
Next to the stopnames you normally find the length, e.g. 8'. This means that the body of this pipe
for the lowest C key is 8' (Appr. 240 cm). A stop with 16' sounds one octave lower.

Expression pedals
The volume of each keyboard is adjustable with:
Expression pedal Choir (only for Rembrandt 300/3000)
With the left expression pedal you adjust the volume of the choir.
Expression pedal Great + Pedal
With the left (for Rembrandt 300/3000 the middle) expression pedal you adjust the Great and
Pedal Volume at the same time.
Expression pedal Swell
With the right expression pedal you adjust the volume of the Swell.
The expression pedals work independently from the adjusted General Volume. For adjusting
General Volume see: “Thumb pistons, Volume.”
Thumb pistons
Thumb pistons are switches that after being switched on or off remain in the same position. For
that every thumb piston has a light build in that lights on as soon as it is switched on.
WM = Werckmeister
By pushing this piston you choose for the Werckmeister III temperament. See under chapter
“Choice of temperament.” As soon as you switch on this temperament the Meantone
temperament will be switched off automatically in case it was on.
By pushing the WM thumb piston again its function will be switched off again.
MT = Meantone
By pushing this piston you choose for the Meantone temperament. See under chapter “Choice
of temperament.” As soon as you switch on this temperament the Werckmeister III temperament
will be switched off automatically in case it was on.
By pushing the MT thumb piston again its function will be switched off again.
MB = Manual Bass
By pushing this piston the pedal board will be coupled to the Great keyboard automatically.
When you play a chord on the Great, the lowest key of this chord will be coupled from the Pedal
to the Great.
By pushing the MB thumb piston again its function will be switched off again.
CF = Cantus Firmus
By pushing this piston the Swell will be coupled to the Great keyboard. When you play a chord
on the Great, the highest key of this chord will be coupled from the Swell to the Great. This way
the effect of an automatic solo can be achieved. In case you use the Swell to Great coupler
already in use the CF function has no effect.
By pushing the CF thumb piston again its function will be switched off again.

FA = Fix Accessories (Freeze accessories)
When you use the couplers and tremulants in the fixed combinations (presets) or in the free
combinations (capture system) or using the thumb piston “0" (cancel) these will change too. You
can avoid this by using the FA thumb piston. As long as this piston is switched on you can only
switch the couplers and tremulants on or off by hand.
By pushing the FA piston again its function will be switched off again.
SET
A thumb piston to program:
!Free combinations (see under “Using free combinations”).
!Stop combinations of the General Crescendo (see under “Using the General Crescendo”).
!Volume-, Tune- en Transposer-adjustments (see under the description of the thumb pistons
Volume, Tune and Transposer).
!MIDI-tabs.
1 thru 8
Thumbpistons to store a personal registration into the capture memory by giving these
registrations a number (1 thru 8) within a memory level (bank). These thumb pistons you need
again to call these stored registrations from the capture memory. See under “Using free
combinations”.
– and +
Thumb pistons with which you:
!Choose a Memory level (bank 1 thru 8). (See under “Using free combinations/ capture
system”.)
!Choose a step to be programmed in the General Crescendo. (See under using the General
Crescendo.)
!Adjust the volume, tune en transposer (see under the description of the thumb pistons
Volume, Tune and Transposer).
!Choose an expander module patch/voice number and a channel number (see under
“Programmable MIDI”).
When you keep on pushing the - or the + piston these will automatically count down or up.
GC = General Crescendo
Piston to switch the General Crescendo function on or off. See under “Using the General
crescendo”.
PGM = Program General crescendo and MIDI-tabs
Piston that enables you:
!To change the stop combinations of the General Crescendo. See under “Using the General
crescendo”.
!To program a MIDI-tab. See under “Programmable MIDI”.
PP thru T
The fixed combinations (presets) are registrations, preset according to musical standards,
starting with PP (Pianissimo: very soft) thru T (Tutti: full organ).
The Tutti piston has two functions. When you play a stop combination chosen by yourself or
from the presets (PP thru FF) the T piston calls the full organ; the normal function of this piston.
However, when you push the T once more you will recall the previous registration.
The presets have been fixed in the factory and cannot be changed by the user.
When you push one of the preset pistons the factory programmed stops will light up accordingly.
It is always possible to switch stops on or off by hand.

0
The 0-piston (cancel/undo) can be found at the far right under the lowest keyboard.The 0 piston
on the organ is duplicated. The 0-piston is also located to the right of the “T" piston.
The pistons have two functions. It may happen that you switch on a preset or add a stop by hand
by mistake. By pushing one of the “0" pistons short you will undo the latest change.
Example
You play the registration of Flute 8', Flute 4', and Flute 2'. After some time you add the Principal
8' and Pricipal 4'. There is always a very short time between switching on the Principal 8' and
the Principal 4'. By pushing a “0" piston briefly only the Principal 4 ‘ will be switched off (undo
the latest change). Not the Principal 8' as well as the Principal 4' will be switched off (according
to the organist this would be his last change.) Actually the organ sees the Flute 8', Flute 4', Flute
2' and the Principal 8' as the previous registration and the organist the combination Flute 8',
Flute 4', and Flute 2 as the last one.
When pushing a “0" piston longer all stops will be switched off at once. Exceptions are: the
couplers and tremulants when the FA piston is switched on and the stops Chorus and
Intonation 2.
RO = Reeds Off
Located to the far right of the presets is the RO (Reeds Off) thumb piston. By pushing this piston
all reeds will be switched off at once. As long as the RO piston is switched on no reeds can be
switched on. By pushing the RO piston again this function will be switched off.
VOL. = Volume
Independent from the position of the expression pedals you may adjust the total volume of the
organ with the piston VOL. in combination with the - and + pistons. The adjusted volume you
can store in the memory. When you switch on the organ the in the memory preprogramed
volume setting will automatically be chosen. If desired you can always change the programmed
volume setting again.
The memory of the volume adjustment is protected so that it cannot be erased when you switch
off the organ or when you unplug the organ from the main power.
The volume can be adjusted between 1 and 25. The choice of volume can be seen in the
display:
