ST MARY-LE-BOW STANDARD SAMPLE SET

The single channel instrument will just fit into the Hauptwerk v4 Basic edition sample memory limit of 3GB (or 3072MB), assuming that most of the sampled tremulant ranks are not loaded and the Hauptwerk tremulant model is used instead. As the sampled tremulant will sound more realistic, it is worth trying to load at least some of the tremulant ranks. For example, loading all non-tremmed ranks along with the tremulant samples of the Great Gamba, Stopped Diapason, Spitz Flute, Cornet, Cromorne and Swell Hautboy requires approximately 2,982 MB of memory (this is with all samples loaded at 16 bit, single loops and using lossless memory compression).

Therefore, for the single channel set, a dual core processor with 4GB system RAM running Hauptwerk Basic Edition on a 64 bit operating system should be considered an absolute minimum requirement. Hauptwerk-V (v5) Lite Edition should prove to be more suitable as it has no sample memory restriction.

For the multi-channel set, a good quad core processor and upwards of 16GB system RAM is recommended; Hauptwerk Advanced edition would certainly be a strong recommendation. The following table gives very approximate figures for the amount of RAM (memory) the organ samples require with various different loading options set. None of these figures take into account the RAM needed by the operating system or Hauptwerk itself. Where no figure is given, that particular loading option (although valid) hasn't been tested, generally because it wouldn't make sense to use it.

* Multiplying by 3 will give an approximate figure. For instance, all three stereo channels loaded at 24 bit, all loops and lossless compression has been measured as requiring 30,013 MB of RAM. It is of course possible to load just two channels (eg Ambient and Surround only), in which case simply multiply these figures by 2

This sample set attempts to replicate the existing instrument at St Mary-le-Bow as closely as possible, with virtually no additions. The only exception to this is a provision of eight pistons for each division instead of the six found on the real thing. The extra pistons are omitted from the main Console screen, so as to give a more authentic visual experience. The Tickell organ does feature a Stepper - as Hauptwerk provides an excellent generic stepper, the use of this is assumed and the forward and backwards stepper buttons on the various displays have been integrated into the Hauptwerk stepper.

A comprehensive range of control options is available in the Settings screen for all organ definitions, allowing the overall balance of individual divisions and perspectives, with a six preset memory function provided for store and recall. In addition, flexible control of noise samples and other elements of organ control (such as stop delay and alternate Swell response) is included, along with the ability to choose between sampled or modelled tremulants. For further details on all of these features and much more, please see the user manual.

Various screen views have been programmed, which include pages optimised for those using two display monitors. Most of these views take advantage of Hauptwerk v4’s ability to create flexible screen layouts with differing aspect ratios, of particular benefit to those using screens in a portrait orientation. Please see below for a comprehensive selection of screenshots.
