A Special Treat – Wersi HD Series

It’s been awhile since we heard from Jeff. Clearly, he’s been hard at work on three videos that show what a great system he has built using a combination of his OAS instrument and a second processor based on macOS to host all sorts of “goodies”. A comment from Jeff:

Hi everyone,

I have published three videos featuring a display system for the Wersi HD series instruments. I touched on this briefly in the Upgrade Manual but didn’t want to be too prescriptive as the flexibility of the HD concept enables every owner to do their own thing and construct a system to their own particular requirements. However, I thought that you might be interested in my implementation, hence the videos.

Essentially the display system is a totally integrated environment for downloading, installing, configuring and operating all of the HD software. In keeping with the overall HD Series philosophy, I’ve employed the KISS principle (Keep It Simple Stupid). Everything we need is contained on one single screen of the display. So there’s none of this scrolling through menu after menu that would be necessary if we were to implement these functions on the organ’s main processor. Furthermore, the use of an independent second processor completely avoids all the restrictions and limitations inherent in trying to run this software in a VST host within the OAX. The result is a much simpler, easy to use, stable and resilient universal operating environment, offering complete software flexibility. And the system is infinitely expandable to accommodate any type of software. Coming soon will be the installation of a Digital Audio Workstation (DAW) which is going to take the instrument to a completely new level of capability.

    I’m looking for a Scala (OAS). Anyone out there have a lead on one for sale. I prefer a working unit but I will consider one that needs repair or an upgrade to V-7.1

    Hi John,

    You’re absolutely right, organ owners have been attaching all kinds of external devices to their instruments for years and years. In fact when I started doing the research for the HD Series project I was astounded at how much of this sort of thing is going on.

    The problem however is that not much of what owners do gets documented, so other owners who want to do something similar, but don’t have same well developed technical skills, are not able to progress. It’s for this reason that I initiated the project, it’s objective being to explain in detail how to go about doing this sort of thing so that owners who might not have had the confidence to do it would be encouraged to have a go. And of course the flexibility of the concept means that many variants are possible, so everyone can do their own thing.

    That’s the ‘special’ ingredient, the secrets of how to do it revealed!

      IIs all right, I thought for a moment, I thought for a moment that you thought it was new and original, and that is of course not so.

    I do not think it’s very special, I’ve been doing the same thing for years, with my Wersi Wega CD600. I also play Hauptwerk, Miditzer, Native Instruments B4 II and SoundFonts on my Wersi Wega CD600. You can see it yourself on my website: http://www.wersi-fan.nl/mijn_orgel.html
    With photos and description. Of course it is only described in Dutch. (Google translator helps)
