SEMPRA „Accordion Fascination“ Installation and playing instructions
General information
Hardly any other "mechanical" musical instrument comes in so many different variations as
the accordion. This is shown by the many different terms for instruments of this genre,
whereby one and the same instrument is sometimes given different names depending on the
country and region. Even the attempt to classify the various designs into categories is only
incomplete.
A distinction is made, for example, between alternating tones and equal-tone instruments.
The alternating tone instruments produce different tones on one and the same key during pull
and push. Equal-tone instruments, on the other hand, always produce the same tone
regardless of the direction of the bellows movement on a key. Diatonic instruments are always
alternating tones, but also have keys that are partly of the same tone. Chromatic instruments
are usually of the same tone, but there are exceptions.
The differentiation between the knob handle and the piano keyboard is the most obvious
outwardly, but (at least for the button accordions) says nothing about the type of tone
assignment.
Figure 1: large, multi-choir piano accordion
Each design probably has its own special advantages, but is not always equally suitable for
every type of music (or even every key). Furthermore, a variety of different playing techniques
and notations have developed for these instruments.
Popular "big" accordions are usually built in 4 to 5 choirs. Analogous to the organs, we also
speak of foot positions, namely 16', 8' and 4' as "even" (i.e. purely tuned) stops. In addition,
there are up to two tremolo registers, which are also in the 8' pitch, but are tuned a little
higher or lower in comparison.
Other accordions have instead of the detuned 8' stops the 16' and/or 8' stops in their own
resonance chamber (Cassotto), which gives a rather dull and soft sound, and maybe
additionally an open 8' stop in the same tuning. Still others even have a high fifth register (2
2/3'), but then usually do not have a detuned 8' register.
Although the keyboards of our instruments (here the organ is meant) differ only slightly from
those of a (piano) accordion, it is often the way of playing that provides a "real" accordion
sound. Just think of the bass (and chord) side of the accordion.

Installation and playing instructions Accordion Fascination - SEMPRA
The assignment of complete chords in major, minor, seventh and diminished and the
arrangement of the buttons (on the descant side of the button accordions) create a very
special characteristic of accordion interpretation. The way the bellows are moved is also very
important for the dynamics of the sound.
Around the world with 80 accordions
But in order to create a really realistic sound impression, even with a practiced performance,
authentic basic sounds are of course also required. And you get these with the sound package
"Accordion Fascination" for your SEMPRA.
The basis of the 95 sounds in this package are not simply directly recorded complete accordion
sounds, but rather individual accordion registers. We have recorded some typical single
registers of different accordions and created a mix of single registers of any kind. These were
put together by our musicians to create new, "virtual" accordions. The advantage of this mix
is that you can combine individual registers from different accordions to a completely new
"instrument" in the form of your own global presets (or even your own sounds).
As a replacement for the above mentioned technical features of mechanical accordions,
SEMPRA provides us with the appropriate technical aids: Touch response, solo chord or even
the foot swell are only the most important ones. But many basic characteristics are already
pre-programmed for you in the new accordion sounds themselves - so you don't need to worry
about them when playing.
When tuning the tremolo registers (in the "real" accordion), for example, care is taken to
ensure that the resulting beat (i.e. the tremolo) is approximately equally fast over the entire
manual range (slightly slower at the bottom than at the top). With the simple detune (i.e. the
detuning) of one sound in relation to another, the detuning is always done in cents (i.e. 1/100
semitones). But this detuning produces a tremolo twice as fast per octave higher and vice
versa! That's why we have broken down the tremolo registers into many small individual
sounds (a new sample every two or three keys) and (just like on the real accordion) tuned
them individually - or detuned them.

SEMPRA „Accordion Fascination“ Installation and playing instructions
Installation:
The data (sound data for the AMADEUS sound module(s) and sound presets) can be found in
the "Accordion Fascination" folder on the installation USB stick that you received with your
SEMPRA. These can be installed from the stick in the usual way:
•Insert the stick into the organ
•Press the [USB] button to open the USB menu.
•Select "Installation" in the left column (file type)
•Move the cursor to the Accordion Fascination folder in the file list.
•Tap on "Install Folder/File" in the right-hand column.
•When the display asks in which sound groups the sound data should be installed, select
"all sound groups".
The new accordion sounds
Single registers and combinations
You will find the new accordion sounds on sound bank 41, here in places 1to 95, with sounds
no. 1...80 being arranged into four fundamentally different accordion sets. Each set consists
of 15 single stops or their combinations, just like you find them in the "real" instrument.
In addition, you will find a tremolo register at position 16 or, on accordion 4, the quint register
as a single register. This is for combining with registers from the other 3 accordion sets.
Chord Sounds
At positions 17 and 18 you will find chord sounds. They play DUR chords on the lower octave
(keys 36 - 47), MOLL chords on the second octave (keys 48 - 59) and simple fifth chords on the
higher keys (repeating).
As a special feature, we offer you sounds on positions 19 and 20, with which you can play the
complete accompaniment. The first pressed manual key plays the corresponding keynote. A
fifth higher, the second key plays the corresponding DUR chord.
For C major, for example, play as follows:
C -> Bass
bound to g -> C-maj chord
offset to G -> Alternating bass
bound to g -> C-maj chord
and so on

Bonus Sounds
On sound squares 81 to 83 you will find typical accordion basses. From place 84 on, we also
provide you with the characteristic stops of a Styrian accordion. By the way, the matching bass
for this would be the one on place 83.
Finally, numbers 91 to 95 are followed by a few more chord sounds for the lifelike
accompaniment.
Example SONGS with presets for the Accordion Sounds
On the BÖHM website we have put a SONG bank for download, where you can find
sample SONGS for the sound packages ACCORDION FASCINATION and also MOVIE SOUND.
This bank occupies the user soundbank 16 when inviting to the SEMPRA. Attention! Your own
SONGS, which you might have already saved there, would be lost when loading! So you might
have to move them to other banks first.
We recommend that you use the MOVIE /
ACCORDION Bank via the "Direct Play"
function in the USB menu.
In this case the bank is temporarily
available for playing as a "USB SONG
Bank". But the data will not be loaded, so
no data in the organ will be overwritten.
Of course you can move SONGS from this USB bank that you like and want to use more often
to free user slots within the 16 USER-SONG banks of the SEMPRA.
An overview of the sample SONGS in the file can be found in the appendix to this operating
manual.
