What is WersiClubUSA? Simply put, it’s a place for current owners along with potential owners to gather, discuss and learn about the Wersi product line or anything related to music production and simply having FUN with music!



  • The 1980’s saw Wersi introduce a digital line of instruments to the world – the CD-Line. The famous Spectra was the wonder of the 1987 Musikmesse and next to the Wersi Helios, is one of Wersi’s biggest selling instruments to date.


  • In the 1990’s, Wersi developed the digital Grand Piano line as well as digital sample based instruments and innovations such as the Livestyle upgrade for the CD-Line, Golden Gate, PhonX, Performer and the Pegasus keyboard.


  • The OAS instrument line consisted of professional arranger keyboards and organs. In 2001, the first version of the OAS instrument line was released running on OAS software… a totally open / upgradable product that over the next ten years would continue to be developed.


  • Fast forward to 2016 and we are now on the OAX (OpenArt-Xtended) generation of products with multiple models available going by the name of “Sonic”. Following in the tradition of all Wersi instruments updates to OAX are released on regular intervals adding new features with each release.

    Just wanted to extend thanks to the OAX support team.. Was having trouble with the accompaniment panel buttons sticking. Would put in breaks and switch variations on its own. I pulled the circuit board, cleaned it with contact cleaner and things progressively got worse.
    Emailed Wersi support and sent them a video and other pics and after a couple of try this and try that it was determined I needed a new circuit board.
    Within two weeks I have received the new circuit board and my OAX 800 is back working perfectly.
    Can’t thank the support team enough. They were absolutely great.

      Good to hear Jim! They have always been very helpful when we contacted them.

    We have a WERSI prisma DX 5 model CP organ in perfect working condition. My mother still uses it occasionally. We need to sell this. Can you give us an idea of price range this is worth?

    • 06/12/2020 at 07:05

      Hi Linee,

      We are not associated with Wersi. Our suggestion would be to reach out to a Wersi dealer and see if they can help you with pricing information.

      • 06/12/2020 at 11:28

        OK, Thanks.

    • 06/12/2020 at 13:55

      The Prisma is well over 40yrs old and was an entry level model, so 50-100 if you are lucky or worst case you may just have to find someone who is prepared to take it off your hands for free.

    I responded to a Windows update prompt on my OAX800. During the update I received the following error message: “MBR Error 1, Press any key to boot from floppy.” Has anyone experienced this problem? Is there a Recovery Mode on the Wersi organ?
    I am a new owner getting my feet wet.

      Don – Suggest you drop a note to oax@wersi.net and see if they can help you out. Although it’s very tempting overall, Wersi recommends not to apply any of the Windows updates.

    On psrtutirial website the Korg styles all have the “STY” filters extension. Anyone know if they will work on the Sonic?

    • 08/03/2019 at 15:16

      Hi Jim,

      I would be inclined to download and try and load one in, firstly natively and then through the Yamaha convertor and see what happens. If it doesn’t work, you can just delete.

      I don’t have time to look today, but more than happy, if you want to send me the link, to give it a try tomorrow evening when I may have some time to turn on.


      • 08/04/2019 at 09:59

        There are lots of styles on the psrtutorial.com website which have been converted to Yamaha format. I have downloaded a few sample
        Korg and Roland styles and converted them to oax and they work fine. Some Roland styles displayed an error message but seemed to load and play ok. Maybe there is no need to buy the Roland converter!

    Had a look through the new manuals of V2.5 (Using Google Translate) and there are one or two new features that look interesting, but overall considering it’s been 12 months since the last update, (Which itself left a lot to be desired) it’s pretty naff, so I still can’t recommend OAX (From V2.00 onwards) as worth bothering with. (Most of the changes and additions customers requested appear to have been completely ignored) Since the release of OAX V2.00, Wersi seems to have completely lost the plot.

    • 07/15/2019 at 18:04

      Hi John and OAX Owners. I have done the download its fine and it is in English when you select it for the download. The Update version instructions are in English after the download is complete. Refer: Settings – Software Update – Update history. .

      The new Music Archive is great, but disappointingly the User Presets are still a jumble with no sorting for alphabetical order which drives me nuts as I have a lot of registrations saved in here.

    Hi. Can any one tell me if it’s possible to connect aKetron Paedal board to the Sonic O1 as when I purchased it I had a 13 note pedal board.
    I have in concerts used my 17 note Wersi pedal board off my old Abicus.
    This pedal board plays sounds on it but not the sound from the Sonic.
    If you play a brass on pets it does not pick up on the Ketron.
    Many Thanks

    PLUS in concert the Organ made one hell of a bang in fact the E V speakers have a limiter so they closed downHas any body experienced this Cheers.

      Are you talking about the Ketron K8 MIDI pedalboard or the Ketron FS6 / FS13 footswitches?

      • 06/08/2019 at 09:26

        Hi Curt its the 13 note K8 Midi

        • 06/08/2019 at 10:43

          Let me see if I can keep this short. It may not work the way you expect. I just did a quick test using a MIDI controller connected to my Sonic. First, the MIDI In port on the Sonic appears to be routed to the sequencer section of the organ vs. what you have selected on a keyboard or the pedals.

          What MIDI channel are you sending from on the K8? For a quick test open a MIDI file on the organ/ OAX1. After you have done that try to play the K8 again. You should hear one of the sounds used in that MIDI file when you play on the K8. It will be the voice that matches the MIDI channel the K8 is sending on.

          Let me know once you get that far.

    Hi Omar,

    There are two power switches on the Scala, the mains power switch located on the mains panel at the bottom right hand of the organ base where the mains power cable is plugged in, and the On/Off switch on the organ console. The mains power switch supplies power to the organ, whilst the On/Off switch turns on the organ. The On/Off switch operates just like the power switch on a standard PC. When activated it shorts together a couple of contacts on the PC motherboard which then sends a signal to the organ’s power supply unit at the back of the console to turn on this unit and so supply power to the organ.

    As a first step, you could try the following:-

    1) Check the fuse in the mains plug
    2) Ensure that the mains power switch is turned on
    3) Check the wiring and connectors between the On/Off switch on the console and the motherboard
    4) Check the wiring and connectors between the motherboard and the power supply unit
    5) Check that the power cable that runs from the mains panel to the back of the power supply is plugged in and properly connected.

    If all the above seem OK then we may be looking at a problem with the power supply unit.


    • 05/06/2019 at 12:22

      If the previous owner ran the power chord out the back of the organ directly from the power supply the front on off switch will be bypassed.

    Hi Everyone,
    I am not familiar with any musical instruments, but I have a Wersi Scala GS 700 sitting at my house that will not turn on. Maybe I am not connecting it the right way or maybe there is something wrong with it. Can anyone give me some guidance?

    Thank you,

    Anyone hear any rumors about Wersi taking over a portion of Lowrey?

    • 01/08/2019 at 09:49

      Where or how did you hear this about Wersi and Lowrey?
      I have heard Lowrey shutting down.

      • 06/08/2019 at 17:29

        Just had communication from Wersi but not to sure what it means?

        “We will soon start in the usa and jump into the gap of lowrey.
        Former Lowrey salesmen will help us and work for us”

        The Wersi download OAX V2.50 will be ready within the next 2 weeks.
        This download will include the option to purchase software to allow importing of Roland, Tyros and Genos styles , updated Wersi styles & drums and a new directory for saving registrations with sheet music

        • 06/26/2019 at 13:09

          They are certainly keeping us waiting for 2.5. Any further inside information Ross?

          • 06/27/2019 at 17:18

            Yep It is still under going testing with Brett Wales. Now saying early July.
            Remember I was advised 2 weeks but this is Wersi time so we just have to wait

    • 05/02/2018 at 09:06

      Thanks Bill – I heard the news last night and just put a small post up on our Facebook site this morning. We had the pleasure of meeting Mark a few times when he was playing at the Dutchland Keyboard show. At the time he was playing a Spectra.

    Hi Curt
    Sorry to say but after having 5 internal problems with my OAX-1 keyboard, I did manage to fix 4 after a lot of searching, one I cannot fix as Wersi in Germany has informed me that I need a new soundboard. Hence I have found that Wersi back-up support is next to none, at least here in England.
    So I am going back to Yamaha, their back-up support is very good, I’ve always had Yamaha keyboards, but I liked the sounds etc. of the Wersi hence the reason I bought one, so now I’m exchanging my OAX-1 keyboard for the new Genos. I must say that I found Wersi Club USA members and your video tutorials very helpful.
    Regards John Simpson

    • 01/07/2018 at 09:10

      Ouch sorry to hear that John. Hopefully, you will check back in with us from time to time to see what we are up to. Please keep us updated on your musical adventures and the Genos.

      I’ve watched a few videos comparing it with the new Korg keyboard and it has some very nice rhythms and accompaniments.
