  Rhythm Designer 


Revision 36 of OAS-7.1 contained a new Optional Package called Rhythm Designer. This was provided with a total of 16 Loadings of OAS into your organ during which you could investigate it yourself. It is now available to purchase from Wersi via an Activation Key. There are also some demonstration Total Presets within OAS-7.1.

Club member Roger Zeebroek has kindly translated the German Manual for this package into English. He sent it to me and I have changed the German screenshots for English ones (except for one) and adapted the translation with a few more explanatory items and a couple of additional screenshots.

You can download a pdf file of this English Manual from the title of this panel which is a link.

The Rhythm Designer requires the OAA and the Drumsets 2007 to be already installed on any instrument before it will work. The package looks very interesting and full of possibilities which will enhance any Wersi instrument. There’s likely to be one or more articles which will look at features of the package in greater depth appearing on this site shortly.

Here is a brief summary of some of the essential features of the Rhythm Designer.


• There are 36 Loop Presets provided by Wersi, contained in the Loop Preset database with 1964 further slots reserved by Wersi. The remaining 2000 slots are for storage of User Loop Presets (see below*), ones you’ve produced by editing the existing ones. Each Loop Preset contains four Loops/Arpeggios appropriate to the name of the Loop Preset. For example, the Loop Preset called Bossa Nova 1contains 4 Loops/Arpeggios called:


 Acc 1  Ac-Guitar Bossa 02  Var A  Var B  Var C  Var D
 Acc 2  Percussion Bossa 01  Var A  Var B  Var C  Var D
 Acc 3  Jazz-Guitar Gipsy 01    Var B

 Var C

 Var D

 Acc 4

 Ac-Guitar Bossa 03

       Var D



Four Variations of combinations of these four playing are available, indicated above. Each Loop/Arpeggio is, in fact, a sound, sometimes an instrument (Acc 1, 3 and 4 above) and sometimes a percussion set (Acc 2 above: percussion sets can be inserted only into Acc 2).  In this example the instruments are all playing strumming loops (as can be heard from the mp3 demos) and the Percussion Bossa is playing - well, percussion Bossa. The volume of each sound can be controlled by sliders Acc 1 to Acc 4 respectively.


• Each of these 4 sounds can be edited. The instrument playing can be changed. In the Loop Ac-Guitar Bossa 02 the instrument preset is 084-000-005 NylonGuitar Acc and that can be changed to anything, though Wersi does issue a warning that some sounds may not work as intended. Obviously a bit of experimentation and common sense is needed in this. Reverb, Attack Velocity, Chorus and Panorama can also be changed.


• *Any changes made to this Loop Preset, including changing any of the four sounds, editing the other parameters, changing the Variation combinations etc can be saved in the list of Loop Presets as a User Loop Preset, starting at position 2000. There are 2000 slots available and you can choose where you wish to save them. Some sort of preliminary organisation as to blocks of positions for particular rhythm genres seems to be called for on the part of the user!


• Each of these sounds is called a Phraseloop Variation. Wersi has provided approximately 650 of them, distributed by rhythm genre within the first 2000 (approx) slots of the Phraseloop Variation database. The remaining 2000 slots are for the storage of User Phraseloops, ones you’ve produced by editing the existing ones.


• There is therefore a considerable amount of space Wersi has reserved within each of these two databases; the Loop Presets database and the Phraseloop Variation database. Wersi has shown in the past that it fills empty slots over time with additional items. I’ll say no more.


• The total editing facilities are considerable. Import a Phraseloop Variation into a spare slot (ACC 1 - 5) of an existing Style: go into Styles editing and look at the Midi-Loops which the Phraseloop Variation is playing: change anything (musically speaking, of course!): export that edited Phraseloop Variation (it could be a completely new “tune”) back into the Phraseloop Variation database......

Sound demos in mp3 format have now been added to the above. Each one is in blue and underlined (7 in total). I’ve also corrected the year!!! Timing errors are mine! I’ve used the same four chords throughout.


Wersi has also provided some demo Total Presets using the Rhythm Designer. The information about these in the Manual is a little confusing but here is how it actually is:


• 0929 Demo RD Bach Arpeggio is missing from the list.


• Numbers 921 to 930 are indicated as having the Rhythm Designer accompaniment plus a Style accompaniment while numbers 931 to 940 are indicated as having only the Rhythm Designer as an accompaniment. In fact, numbers 921 to 924 inclusive have both playing while numbers 925 to 940 inclusive have just the Rhythm Designer accompaniment playing. In addition, in numbers 925 to 940 the Style Accompaniment has been removed by muting ACC1 to ACC5, rather than via the ACC On/Off button on the panel.


This means you have to go into Settings > Edit Styles in order to un-mute them individually to hear what the effect of that is, or you could untick/tick the Acc1-5 Aus box under the Acc tab to switch all five Style Accompaniments on and off at one go. If you untick this box first you can then switch the Style Accompaniment on and off with the panel ACC On/Off button: though you will lose the automatic bass line with the RD accompaniment that way.


• Here are some demo sound files in mp3 format of some of these Total Presets. Please remember: these are just demos - I’ve just copyrighted all my mistakes.



1. Preset 921: Harp Arpeggio. This goes from Var A through to Var D, finally adding the Style Accompaniment. All settings are as the Preset. This demonstrates how the Intros, Breaks/Fills and Endings do not contain the Rhythm Designer’s contribution. The Style is Wersi 8 Beat 1.


 The Loop Preset is whatever you last used. It has no relevance here.


Acc 1 Harp Arpeggio 08 Var A Var B Var C Var D Loop
Acc 2 Harp Arpeggio 10 Var A Var B Var C Var D Loop
Acc 3 Harp Arpeggio 01 Var A   Var C   One Shot
Acc 4 Harp Arpeggio 04 Var A   Var C   One Shot



The One Shot Arpeggios do not show up in the full demo because I’ve used an Intro from the Style, so here is how Var A on its own sounds from the start.



2. Preset 926: Arpeggios Mix 2. This goes through all the Rhythm Designer Variations in sequence, finally adding the 8 Beat 1 Style

 Accompaniment. The Song volume is set to maximum.



Acc 1 Strings Arpeggio 08 Var A Var B Var C Var D Loop
Acc 2 Music Box Arpeggio 03   Var B Var C Var D Loop
Acc 3 Harp Arpeggio 09     Var C Var D Loop
Acc 4 Piano Arpeggio T100 04       Var D Loop



3. Preset 935: Slow Rock. The four RD Variations plus the Wersi Slow Rock Style Accompaniment added at the end. No Breaks.



Acc 1 6-8 Ac-Guitar Ballad 01 Var A Var B Var C Var D Loop
Acc 2 6-8 E-Guitar Muted Ballad 01   Var B Var C Var D Loop

Acc 3

6-8 Ac-Guitar Slow Rock fast 02     Var C Var D Loop
Acc 4 6-8 Piano Slow Rock 01       Var D Loop



4. Preset 940: Boogie Woogie. The four RD Variations in sequence but no Wersi Rock ‘n Roll 1 Style Accompaniments added (other than the Drums and Bass).



Acc 1 Piano Bass Boogie Swing 01 Var A

Var B


Acc 2

Piano Bass Boogie Swing 03     Var C Var D Loop
Acc 3 Piano Boogie Swing 03     Var C Var D Loop
Acc 4

Piano Boogie Swing 0

Var A Var B     Loop


These are used in pairs to provide a change of style, the piano bass boogie complementing the ordinary boogie. Anything more complicated and it becomes muddled.


I hope you have benefited from this short incursion into the world of the new Wersi Rhythm Designer. I still have further to go with investigating it and I look forward to contributions to this page from those of you who are also investigating the software.

Received from Lloyd Erickson:

I have been trying out the new Rhythm Designer and today I wanted to play some midi files that are in my Abacus. When I went to play them I could only get the drums, nothing else. This has never happened before and I suspect that the Rhythm Designer software was the cause.

I rebooted the system and all was OK.

Just wondering if anyone else will experience this "Glitch". It's not likely that someone else will decide to play midi files after using the Rhythm Designer but thought I would bring it to your attention.

Further thoughts from Lloyd Erickson:

I have used the last of the 16 activations so I am no longer able to access the software. I have mixed thoughts about the software.

1. I think that the software needs to be checked out further due to some glitches that have occurred.

2. The price is a bit too high I think and I wonder with all the great styles in the Wersi now, do I really think that this software will warrant installing it.

3. Wersi always has interesting updates to improve the functions so you can choose to use them or not. No other organ offers you the convenience of being able to load new sounds, styles plus update the operating system, enabling one to keep the machine you originally purchased without spending a large sum of money to buy a new one that will be outdated in two years.
