SEMPRA SE20/40/60 operating instructions
Congratulations
You have chosen an innovative, modern and melodious musical instrument - a Boehm SEMPRA Organ.
We break new ground with SEMPRA and introduce a new level of musicality, hitherto unknown in an
organ. An overview of the special characteristics of SEMPRA:
VERY QUICK - the fastest time of all current organs: SEMPRA is ready to play in only 5 seconds! We set
a modern industry standard in the organ with the SEMPRA realtime performance Operating System.
The result is a lightning-fast performance in all functions that would be unavailable using, for example,
Windows - or Linux-based PC organ systems.
Ease of use - the completely newly designed, easy-to-understand user interface makes playing and
registering the organ a simple pleasure.
TOUCH or button - virtually all functions are either available on the ultra quick 9 "wide view touch
display or can be reached via the control buttons and knobs. You have the choice!
3D PRESETS - new and innovative: up to 6 single Global Presets (General settings) incl. the style or
playback accompaniment (MIDI file), etc. are saved together and are instantly available in SONGS.
These SONGS can be sorted at any time according to various criteria using the appropriate control
buttons. They can be catalogued in albums and topics for easy retrieval. So, you can anytime instantly
find and retieve your settings from amongst hundreds and thousands of SONGS. This completely new
preset system provides for a intuitive playing.
MANUAL PRESETS - new for Böhm: with the practical manual preset buttons between lower and upper
manual you can call up the 6 linked presets of the currently selected SONG. These buttons are available
while playing, without taking your hands off the keyboards. The two buttons left turn through the 6
presets in ascending or descending order (not available in modified organs).
EASY STYLE CREATOR - styles can be modified using the new EASY STYLE EDITOR This is easy to use,
also for the quick recording of new tracks, patterns and and intros etc. Styles in the Yamaha® format
(up to 5 of tyre) can be used immediately or edited and saved it in the style library of SEMPRA.
INTERACTIVE PLAYBACKS - MIDI files can be used just as aflexibly as styles - this dream becomes reality
with SEMPRA. MIDI files can not only have adapted instrumentation, but also by using markers can be
divided into up to six sections such as intro, verse, chorus, bridge, etc. These sections or pattern can
play with the style pattern and at the push of a button, at any time, you can order and control so the
flow of the MIDI files and thus your music piece is flexible. They become a perfect song-related support,
and the use of a MIDI file in SEMPRA is not as restricted as in a conventional file player but becomes
part of your arrangement.
Advanced memory techniques - what you store in your SEMPRA, is always retained. There is no RAM
memory which could be lost. All your data can be delete directly and also saved at lightning speed in
the internal flash memory. If necessary, this can even be backed-up. Your working data can not be lost.
Saving/loading data on connected USB storage media (memory sticks) takes place at lightning speed.
USER accounts –this way each SEMPRA becomes your SEMPRA. Your family or friends want to play
backing tracks, also on your SEMPRA, but with their respective own registrations, styles, etc.? No
problem: You can put multiple user accounts on the organ. The individuals own data is then in the
currently enabled user account. Any player who uses the organ, can hold his own data in his personal
account.

10
SEMPRA SE20/40/60 operating instructions
And the best: user accounts can be exported to a USB stick and then the complete organ can be played
from the stick. In this way your friend who has also a SEMPRA, can save his organ data to a stick which
can be used in your organ without altering your data settings.
REAL Organ - A drawbar system with 9 footages - anyone can do that! In addition to that classic
Hammond configuration, the new SEMPRA drawbar organ offers various other legendary organ
simulations, with expandable foot position range (up to 15 choirs!) and sensational sound. Of course,
all typical effects of the respective organ type such as full percussion over all foot positions, Leslie or
Phasing Rotor, Celeste, Vibrato and Chorus are realistically reproduced. The RealOrgan comes
standard with several organ types. With extension packages you can also add the drawbar characters
of many further vintage organ types. You will not find such a versatile and sounding drawbar system
as the BÖHM RealOrgan with any other organ - a dream for all friends of the legendary sound.
MULTI-SOLOCHORD - a well known effect: the Solochord responds according to the notes played on
the accompanying manual and enhances the melody with is own sounds. For example, with only one
finger of the right hand to play a solo clarinet and add a polyphonic saxophone set via Solochord in the
same way as similar functions in other manufacturers.
At the SEMPRA, the possibilities go further still: you can make any manual or pedal instrument an
individual Solochord instrument. Each of these instruments can also still play a total of 14 different
types of Solochord. For example, a Glenn Miller solochord set on the right, on the left a choir with trio
lineup, on the right lower manual the transposed strings... no problem. This innovative feature opens
completely new creative freedom in the playing and arranging!
Cloud Studio integration - if your SEMPRA is equipped with the optional Böhm Cloud Studio, you will
find its sounds integrated into the respective sound groups and categories. Now you can play virtual
instruments and sample libraries like e.g. the pre-installed Steinberg Halion6 / absolute 3 package
which can be combined with the AMADEUS sound of the organ. At the same time, the large touch
screen of the cloud Studios you show the manuscript of your piece of music. The manuscript can be
linked with the preset chosen on the organ. Nothing is more convenient!
In the following chapters, we describe the above functions, and many other functions of your
SEMPRA. Many functions are intuitive in use. However, we ask you to read this manual thoroughly
and understand the explanations as they relate to the SEMPRA. So, you will best learn, and
appreciate the many exciting possibilities. Much pleasure for you!
Your
BÖHM Team

SEMPRA SE20/40/60 operating instructions
Installation of the organ
Depending on the model and design your SEMPRA consists of several parts:
SEMPRA SE20 - 2-manual keyboard version
The two-manual-keyboard version of SE20.
•Set the instrument on a sturdy table or a frame.
Use only suitable keyboard tables or stands,
which offer a sufficiently large support surface
- at home as well as on the stage -.
•Make sure that the SEMPRA on the table/base
is securely fixed and cannot slip off.
•Now plug the music stand into the designated sockets at the back of the control panel and take
- as described in the following section - the connections (power cord, line out for external
amplifier/mixing desk, if necessary, pedal and swell ...).
•Place if necessary the free foldable pedal and the sill under the organ and connect as explained
in the following section. to the back.
•Insert the mains plug into a socket.
•The organ is now ready to play.
SEMPRA SE20 - home
In this version, the SE20 has a complete solid wood
frame incl. active speaker system, sills and (usually)
bass pedals.
•Decide where the organ is to go. To prevent
damage you should select a site where the
instrument is not exposed to moisture, nor
excessive heating (radiators).
•With help lower the upper part onto the lower
part, and slide the rubber feet from the bottom
of the keyboards into the recesses provided for
this purpose in the side supports of the base.
This top is firmly fixed on the base.
•Now plug the music stand into the designated
sockets in the bar at the back of the control
panel and remove - as described in the following
section - the connections (power cord, speaker
system, pedal and foot skirts...).
•Place the swell/bass pedal unit, or the 25-key pedal in front of the base and insert the connection
cable(s) into the appropriate socket(s) in the bottom of the base. Note the different plugs/sockets
for the expression pedal or the bass pedal.

12
SEMPRA SE20/40/60 operating instructions
•Now carefully slide the pedal unit into the box of the base. Make sure that the unit is not tilted to
avoid pressure points in the wood.
•Insert the mains plug into a wall socket.
•Place the seat before the organ and adjust to a comfortable seating height.
•The organ is now ready to play.
SEMPRA SE40 / SE60 home
The home model consists of the base with active
speaker system, the keyboards and the pedal
unit (17 or 25 keys).
•With an assistant place the upper part
on the base. The electrical connections
take place automatically using a multi-
pin plug/socket right at the bottom of
the side panels or in the table. Place the
upper part carefully so that the plug and
socket fit together and slide the wooden
pins in the side beams of frame into the
corresponding holes in the side panels
of the keyboards. Attention: Take care
that you do not trap your, or your
assistant’s fingers!
•Now plug the music stand into the
sockets at the back of the control panel.
•Place the pedal - sill unit, or 25-key pedal in front of the base and plug the connection cable
into the appropriate sockets in the bottom of the base.
•Move the pedal unit into the box of the base. Make sure that the unit is not tilted to avoid
pressure points in the wood.
•Insert the power cord into a power outlet.
•Place the seat before the organ and adjust to a comfortable seating height.
•The organ is now ready to play.
Note: All necessary connections for the operation of
the HOME model are automatically made via the
connectors between the upper and lower part. If you
want to connect the organ with other components,
you will find the connections behind the flap at the
back of the upper part.
You can open it by pressing on the door, the lock is
released and the flap can be tilted downwards.
You can now access the connections.
This is closed by folding up and some pressure on the catch.

SEMPRA SE20/40/60 operating instructions
Switching the organ on and off
Turn on the SEMPRA:
•On the right side panel of the organ you will find the power button. Turn
the organ on using a short press on the button.
•A modified stage Overture / SEMPRA SE20 turn on the organ as usual at
the mains switch on the back of the shell.
•The start screen appears in the display
after 5 seconds:
•If multiple user accounts are installed
you wil be prompted during the startup
process, to select the account you want
to use. Select the desired account by
tapping the desired account (or button)
then tap on the Enter button on the
display or the button [ENTER]. By
turning the [dial] right of the display
confirm the selected account.
•The display now changes to the basic
screen, the organ is now ready:

14
SEMPRA SE20/40/60 operating instructions
Note: After switching on, the "BASIC SONG" (list on the left of the display) and the "CLEAR
REG." preset are always displayed first (lower of the 6 fields on the right of the display), or, if
you have created further "Cl.Reg" presets, the uppermost one is selected. This is a basic preset
that sets the organ to a defined initial state and serves as a starting point for new registrations
to be created. The corresponding CLEAR REG. Preset can also be called up at any time by
pressing the [CLEAR REG.] button right on the upper control panel
Switch off the SEMPRA (all versions, except converted Overture organs):
•To switch the organ off press the power button. The organ will be shut
down and a backup of the latest data changes will be automatically saved.
Then, the organ is switched off permanently.
Power off on upgraded Overture organs:
Caution! As in the upgraded Overture the previous power supply is maintained and a "shutdown" via
the mains button is not possible, you must use the display menu "shut down." Now a backup of the
latest data changes will be saved.
If you have a converted Overture, please turn it off as follows to ensure that all previously changed
data is preserved:
•Press the [MENU] button below the data wheel.

15
SEMPRA SE20/40/60 operating instructions
•The menu display is shown. Tap on field
[Shut down instrument].
•A window appears as shown. Confirm
that you want to shut down the
instrument by tapping on [ENTER] in the
display type or press the [ENTER] button
on the panel.
•The system will now shut down and the
data backup is written.
•Updated SE40/60 organs will directly shut down
•Updated SE20: When this window
appears in the display iut is safe to turn
off the organ using the [power button]
on the rear panel.

16
SEMPRA SE20/40/60 operating instructions
Notes for SEMPRA organs with Cloud Studio:
•The switching on and off the organ is performed in the same way as described.
•The organ and the integrated Cloud Studio will shut down together. But, please note:
•When switching on, the actual organ is playable after approx. 5 seconds, with the appearance
of the basic screen. The Cloud Studio, however, takes about 1.5 minutes to fully install, because
first the sample material has to be loaded into in the main memory of the PC system.
•So we recommend to start playing, or to use the first SONG preset with cloud Studio sounds
not before the complete loading of the Cloud Studio. For more details, see the separate
operating instructions of the Cloud Studio.
Power on/off synchronisation of organ and Cloud Studio
When you turn the SEMPRA off and then on again too fast - before the Cloud Studio was also
completely shut down and switched off –it can happen that the Cloud Studio does not restart again
with the organ, because the switch-off process of the Cloud Studio is still running, while the organ
starts already again. The Cloud Studio is then further turning down in the background and is therefore
not ready to play. It would rather launch if you back off the organ via the power button because it
responds to the impulse.
To re-synchronize the power on of the organ and the Cloud Studio in such a case, please shut down
the organ –after the Cloud Studio has completely been turned off –once through the menue (same
procedure as described above for the updated Overture organs).
After that the organ and the Cloud Studio can be launched again together with the power button.

SEMPRA SE20/40/60 operating instructions
Lighting SE40/60
SEMPRA-SE40 and SE60 organs have several lights for the console, the pedal room and the musicstand.
These lights are automatically activated when the organ is switched on.
You can dim the individual lighting sections, i.e. change
their brightness. Tap the [Menu2] button at the top right
of the control panel.
The display shows a menu with several buttons to switch off/on the several lighting sections, and
sliders for dimming the corresponding sections (Attention: Panel 2 is not active on these models). Tap
on the corresponding button to switch the section on or off.
To dim a section, tap on the corresponding slider on the display and use the data wheel to adjust the
desired brightness. Exit the menu with the [ESC] button.
Note: The lighting settings are automatically saved. The next time the organ is switched on, it will start
with the set lighting configuration. If you are working with more than one user account, the storage
will be done in the active account. You can therefore define an individual setting for the lighting for
each of your user accounts.
