The Wersi Implementation

The 320 Paramount sample set is featured here, running in the Advanced Edition of Hauptwerk. This instrument will also run in the Basic Edition of Hauptwerk. A range of sample resolutions are configurable depending on how much RAM is available. The highest resolution (24 bit uncompressed) requires 3.3 GB of RAM to run both the samples and the Hauptwerk software. The 320 sample set requires 1 GB of disc space. For the installation of additional sample sets, disc capacities of between 50 GB and 400 GB are recommended. Hauptwerk specify Apple Mac systems as their preferred computing platform, and for optimum performance, reliability and sound quality, having other programs running simultaneously on the same processor is not recommended.

The implementation of this virtual instrument on a Wersi HD Series organ includes three special features. Firstly, all three virtual instrument manuals are playable in any combination from the two Wersi keyboards. This is achieved by using the OAS Selectors to specify the required manuals of the virtual instrument. Secondly, any two virtual instrument manuals can be played on the same Wersi keyboard using the organ’s keyboard split function. Thirdly, stop combinations are programmed into the Master combination pistons of the virtual instrument, and these are mapped to the OAS Total Presets. In this way a complete combination for the entire instrument can be selected from a Total Preset and/or the Wersi thumb pistons, and changed instantly by advancing to the next Total Preset. Details on how all of these are accomplished are provided in Chapter 6 of the Upgrade Manual.  

The Demo Recordings

Although the Hauptwerk software contains both a MIDI recorder and a high quality digital audio recorder, the demos have been recorded through the normal Wersi sound system to provide an accurate representation of how these would sound on your instrument. The Hauptwerk audio recorder enables high definition 32 bit studio quality professional recordings to be made if required. The instrument’s blower noise has been disabled for the recordings, but can be easily activated if preferred. The pipes of all the Paramount models have been sampled dry, so a degree of reverberation has been added using the reverberation unit in the OAS external audio inputs system.

The Paramount Organs

All the models in the Paramount Organ series are constructed from samples taken from the finest private and public theatre organs installed throughout America and the UK. The best ranks have been collected to provide the organist with unparalleled quality. All samples are in better than CD stereo audio quality with the Solo ranks emanating from the right channel and the Main ranks emanating from the left channel. Paramount models use the actual recordings of each pipe both with tremulant on and with tremulant off rather than synthesising this effect in the sample player software. This produces a much more realistic, authentic theatre organ sound. Considerable time and effort has been expended in voicing the instruments using the extensive suite of high precision tools available in the Sound Forge software. Not only have the notes within a rank been regulated, but also the various ranks have been taken together and meticulously voiced to blend into a musically satisfying ensemble.

The Hauptwerk Sample Set

The Paramount organ series is available in four progressive models and one stand-alone model. The progressive model range starts with the 310 model comprising three manuals and ten ranks. This model is available free.  The next model in the range is the 320 comprising three manuals and twenty ranks. Next is the 332 model comprising three manuals and thirty two ranks, and finally the 450 model comprising four manuals and fifty ranks. Typically each higher model in the range contains all the stops of the previous model, but expanded to include an additional set of stops and ranks. Each of the models is a separate instrument in its own right, so successive upgrades from the 310 model to the 450 model would result in four completely independent instruments being installed. The 341 model is a stand-alone model and has a different specification to those in the progressive range. This makes it more suitable for playing jazz style interpretations. The 341 model comprises three manuals and 41 ranks.

The second demo features the solo sounds of the instrument. Use is also made of the Sostenuto facility on the Great manual, controlled by a Wersi footswitch, to enable sounds to be sustained whilst moving from one keyboard to another.

Over The Rainbow

The first demo showcases the ensemble sounds of the instrument, together with some of the special effects. Use is also made of the Second Touch facility on the Accompaniment manual, controlled by the Wersi Dynamic function, to bring in additional stops as required.
