HD Series OAX Upgrade Manual – Part 2

More news from Jeff regarding the HD series:

I’m pleased to announce that Part 2 of the OAX Upgrade Manual is now online. In this part we cover the installation, configuration, testing and integration into the OAX of a number of HD software packages. The following chapters are now available.

Chapter 5 – Installing and Configuring Kontakt

I’m indebted to Curt from WersiClubUSA for his excellent videos on the OAX external MIDI sounds system, information from which I’ve used extensively to construct this chapter. For optimum performance I’m recommending that we use the dynamic method of MIDI channel assignment. This gives us the most efficient, flexible implementation for allocating and selecting sounds, and seamless integration with the OAX internal sound allocation system.

Chapter 6 – Installing and Configuring Hauptwerk

This proved problematical largely due to the pre-configured Hauptwerk installation that Wersi have provided on the Sonic. This has two major deficiencies. Firstly, it’s configured only for two manual virtual instruments. A good number of the virtual instruments in Hauptwerk are three manuals or more. Secondly, it doesn’t allow stop combinations set up in Hauptwerk to be selected from the OAX total presets and/or thumb pistons, which is the way a pipe organist would want to play it. The good news is that we have devised a new Hauptwerk configuration that resolves both of these issues. It’s scalable to virtual instruments that have any number of manuals and can handle any number of stop combinations directly from the OAX. Once again my thanks to Curt for his valuable help in testing this out for me on the Sonic, and verifying that it actually works!

Chapter 8 – Further Enhancements

This is identical to Chapter 8 of the OAS Upgrade Manual. At the second processor level there is no difference between the two systems. I thought it would be useful however to have a separate chapter on future developments given the potential that a general purpose independent processor brings to the instrument, both in customising the instrument to a user’s particular preferences and also providing all manner of features not available in the OAS/X. The ability to select a complete set of sounds and registrations for a given piece of music automatically from the sheet music is an example of this. If you haven’t checked this out yet you can find details of how this is accomplished in the section entitled ‘Automatic Loading of Sounds’ at the end of the chapter.

Still to Come

Work is in progress to construct the OAX version of Chapter 7 – Installing and Configuring VB3-II. This is the new Virtual Hammond Organ from GSI. There are two requirements here. Since it’s a general purpose piece of software designed to work with a wide range of MIDI systems, to get the best out of it we will need to construct a customised VB3-II configuration suitable for implementation on the Wersi. Also this new version has a user programmable preset facility for its sounds, and these presets can be selected directly by their MIDI Program Change numbers. So as with Hauptwerk, we will be able to select these from the OAX total presets. Given that a VB3-II preset captures every single control on the instrument plus a full set of drawbars for both manuals and pedals and all the parameters on the various settings menus, this is a very powerful feature and a significant improvement on the previous version.
