    Just had an email from Wersi – OAX v2.60 is coming!!

    Thanks, Mark. I have come to find out that I downloaded V2.5 three days before the -01 version came out on the 21st. I have -01 in and my volumes seem to be more normal as they were in 1.51. I’ll keep looking things over.

    Did the V2.5 Installation last night successfully. However, the Version now comes up as 2.50-00. I just saw one done at the beginning of the week from the same download site and it came out to Version 2.50-01. Any difference between the two? V2.5 changed my volumes significantly.

      Hi Spike,

      I had issues with levels after moving to 2.50, as it essentially zero’d all my custom dB settings. See my comments and solution a couple of posts below.

      With ref to 2.50-00 vs 2.50-01, yes, I would make the change. Whilst not experienced any issues myself, Ross had some problems with saving to Music Archive with -00, which he has not experienced since going to -01.

    I wish to change to Oax2.5 from oax 1.52.

    I have read from this site that oax 2.x have problems of sound quality and stability.

    If I change to 2.5, it is possible to back to 1.52 in case the sound quality doesn’t like me?.

      Hi Ramon,

      I’m not 100% sure but I suspect that if you do a “Complete Install” (not an update) it will re-install everything needed to revert back to the 1.52 level. I would recommend that you take a backup so you can re-load any user presets, voices, etc. that you may have created.

      Although it’s a subjective thing, I think you will be happy with the way your instrument sounds once upgraded to 2.50-01. There are several changes and improvements from 1.52.

      Let us know what you think after you give 2.50-01 a try.

        Thank you Curt,

        I will try this weekend…

      Hi Ramon
      I agree there has been a loss in sound quality since 1.52 I no longer get the fuzzies when I play, it just does not sound the same anymore. However we have no option but to move on with new updates otherwise we will be left behind with new features in future updates

    Hi All,

    Looks like OAX 2.50-01 has been released today. Just downloading now, but not had any problems with 2.50-00, so no idea what the update addresses yet.

      Software version: 2.50-01

          Did a recording with 2.5-01 earlier, and whist the Sonic sounded fine when being played, the playback via the Audio Recorder was awful – all muffled and low.

          Thought the issue was Output settings related, so had a look and my custom settings had all been reset to 0dB, so did a bit of messing with those, which made that recording playback sound ok, but when I next played, it was all out.

          Eventually, after about an hour of fiddling, I reset Input and Output settings to Factory default and all is now working ok. I was only using custom settings for each as original Factory defaults were bad when. I first had the 800.

          I thought I would share in case anyone else experience the same issue.

          I have also purchased the Yamaha Styles converter, but too late on Friday night to get a code, so will hopefully get this week .

          • 07/21/2019 at 18:09

            Good info Mark. I did a recording or two so far with the OAX audio recorder and the first thing that I noticed was the output level was much improved. Perhaps a bit too early to call it “fixed” but so far I’d say it is an improvement vs. previous versions of OAX.

          • 07/21/2019 at 18:48

            I purchased on Wednesday and haven’t received a code

          • 07/22/2019 at 04:23

            HI Jim Krause
            Check your junk mail folder in case it has gone in there as that is quite common these days, if not contact where you purchased from.

    Hi Curt
    As I posted in the Synthzone forum apart from a few features, (Like the music archive) it addresses none of the complaints of current owners, but adds dubious features that very few will ever use. (Very few used the vocal harmoniser in OAS (Preferring to use external equipment, or in the case of OAX a VST plug-in) yet they have now included the equivalent in OAX (Which few if anybody asked for) which seems to be a complete waste of resources)
    Sorry to say but since OAX V2.00 Wersi instruments are just a joke, and it’s no wonder a lot have been sold as owners have moved on. (Your videos on interfacing OAX with Ketron equipment must be a godsend for those that can’t afford to change their instrument)
    Also as the VST Host is one of the saviours of OAX (You need to put the work in though) the fact that Jerry has found a problem already, proves what a joke OAX is these days.

    • 07/16/2019 at 07:12

      Hey Bill, Good to hear from you. It’s been a while. It is disappointing that Jerry has run into an issue already. I’m hoping I get time today to capture the update. I was planning on doing a before and after with a Yamaha style or two to see if we can tell the difference although I only have older Yamaha styles on-hand. Not sure how much that will show compared to a newer Tyros5 or Genos style.

      • 07/16/2019 at 07:44

        Curt, if you want access to some Yamaha styles check out the facebook group “Yamaha Expansion Packs and Styles”. Under the files section there are lots of free styles available to download.

        • 07/16/2019 at 07:52

          Thanks Geoff, Looking at it now. Think I’ll pick a few, download and see if I can tell the difference with the style converter activated on OAX.

          • 07/16/2019 at 09:10

            I just received my activation code and converted a few random styles from my Tyros days, and they all convert and sound excellent.

  • 07/15/2019 at 18:43

    I updated my OAX1 and there is a problem when loading my Kontakt VST. Will have to convert back to 2.00


    • 07/16/2019 at 07:14


      Tell us more. I currently don’t have Kontakt loaded on my Sonic, so I’m not able to compare before and after. I suppose I could install Kontakt before I upgrade OAX just to see what I learn.

      • 07/16/2019 at 21:18

        All is well now. It obviously did not like something about the saved Kontak preset from the other version. I loaded a new instance of Kontakt, reloaded my saved instrument file which loaded all my instrument samples, then saved the new VST preset.

    A quick update as of Mon 07/15/19 afternoon:

    We have downloaded all the update files and we also purchased the Yamaha Style converter from Musicstore. More to come on the update and the style converter later this week.
