The Armley Schulze
Although the organ was built for a privately owned timber structure, Edmund Schulze must have suspected that the instrument would eventually find its way to a church environment. The scaling and power of some of the stops suggest as much and - in Armley - the acoustic approaches that of a small Cathedral. Indeed, although the reverb time is just in excess of 3 seconds, St Bartholomew's Church is a very resonant building, resulting in a significant component of reverberated sound being present even in recordings taken close to the pipework. The organ is situated in the chancel area, high on the north side and its power is very keenly felt in this part of the church. Further west, the power and brilliance is tamed (the famous five rank Great Mixtur becomes less strident) and the church's resonance increasingly affects the organ's sound, as would be expected. As has been discussed, the organs of Schulze were highly influential to the organ builders of England in the latter half of the 19th century. In true German romantic tradition, this instrument sets the flue chorus at its heart, but – unlike quite a few of its continental contemporaries – a reasonable variety of chorus reeds are provided. Indeed, for a builder who was noted for his innovations and developments in flue pipework, the reeds at Armley are of a uniformly excellent quality and expand the range of suitable repertoire significantly. For example, whilst it would be expected that the German late classical and romantic music of the likes of Mendelssohn, Rheinberger, Liszt and even Reger would sound good on this instrument, much of the French romantic period works well too. Although the Schulze sound is quite some way from that of a Cavaille-Coll, most of the basic constituents of that style of organ are present nonetheless. English romantic repertoire is also reasonably well catered for, albeit the sounds of later Willis and twentieth century Harrison have moved some distance away from mid Victorian Schulze. Music from earlier periods can be successful, although the lack of mutations inevitably means that not all baroque music can be performed authentically. The four manual divisions have what can be described as “terraced dynamics”, with the Great containing the loudest stops, whilst the Swell, Choir and Echo have progressively quieter sounds. The Pedal underpins each division very effectively and even the quietest stops of the Echo are generally not overpowered by the Pedal 16' Sub Bass. If a quieter 16' tone is desired, there are coupling options on all manuals. During the latest rebuild, the Choir and Echo divisions were moved to the same level as the Great, thus allowing the more delicate sounds contained here to be heard more effectively. The Swell is situated above the Great and speaks out clearly into the Chancel – the highly efficient enclosure allows for considerable dynamic changes to be employed. Despite its romantic leanings, each manual has a proper chorus based on a 16' pitch – the Great Mixtur, Swell Cymbel and Choir Cornett all have harmonics from the 16' series sounding in the treble of their compass and so require an appropriate 16' manual stop to be drawn for these stops to sound as intended. Despite this, the Schulze Principal chorus work is noted for its brilliance and power … nowhere is this more evident than the famous Great Mixtur V, which has been described as being like “canned lightning”. Indeed, so impressed was Arthur Harrison when he first visited Armley in the early twentieth century, he noted the composition of this stop accurately for future reference. Possibly the finest stops at Armley though are the flutes – on every division there are flute families at 16', 8' and 4' pitch and there is a real contrast between the different families. Anyone lamenting the lack of an 8' + 2' combination is reminded that with a manual compass of 61 notes, playing 16' + 4' up the octave is often a viable alternative. The families of strings are no less impressive, with excellent options on the Swell for French music (especially the keen sounding Gamba) to the rather quirky Cello und Violone on the Choir, whose chiffy starting transient is meant to sound like the attack of bow on string. Possibly the most flexible stop on the Swell is the Celeste (still bearing its original Rohr Flöte stop knob as mentioned previously). Whilst it's probably at its best when combined with the Salicional, when added to the Gamba a French sounding Voix Celeste is the result, whereas Celeste and Flauto Traverso 8' gives a very pleasant Unda Maris effect. Although individual registers can and do sound very impressive, Schulze's strength as a voicer was his ability to allow different stops to blend with one another, producing a great variety of new sounds. As alluded to above, trying combinations of stops at different pitches can be very rewarding. The chorus reeds can also give good service as solo reeds with the Great Trompete being a very good example of this. When carrying out his restoration work in 1905, J.J. Binns was largely conservative in that he respected the voicing traditions of Schulze and made no tonal alterations, save for a raising of the overall pitch (this was partially reversed during the work in 2004). However, his installation of tremulants to Swell, Choir and Echo have further enhanced the romantic credentials of the organ. Of course, use of these is entirely optional and whilst the typical Binns style may be a little fast for some tastes, there's no doubting the additional possibilities they present.
Alongside the standard 57 stop organ, which only incorporates the couplers and playing aids that are found on the real instrument, an enhanced organ definition file is also provided as part of the 57 stop sample set. This expands the range of possibilities by including sub- and super-octave couplers for Swell, Choir and Echo, Basscouplers for all manuals, a 32 note pedal compass, additional composition options for the Swell Gamba and Cymbel as well as a virtual enclosure for the Echo division. Various additional stops using carefully manipulated versions of the Armley samples have also been provided. These allow for a “clean” Great chorus to 2 foot pitch, an extension of the Swell flute family, the provision of a cornet on the Echo alongside a couple of useful enhancements to the Pedal. Additionally, the Great 16’ and 8’ reeds can be played on the Choir - the appearance of the Great Trompete on the Choir may be separately voiced to give true solo reed possibilities. The standard and enhanced organs are available in single-channel (Chancel only) and multi-channel (Chancel, Nave and Surround) versions. 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 five 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 a section dedicated to the enhanced organ controls. Various screen views have been programmed, which include pages optimised for those using two display monitors. The left and right hand jamb 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.
Computer requirements vary depending on whether the single or multi-channel set is loaded. The sample memory limit of 3 GB for Hauptwerk Basic edition means that Hauptwerk Advanced Edition should be considered essential for both single and multi-channel variants of the complete set. For the single channel set, a decent dual core or (ideally) quad core processor is recommended, alongside 16 GB of system memory (RAM). The multi-channel complete set really does require 32 GB or more of system RAM, alongside a fast (i5/i7) quad core processor.
The following memory usage table gives approximate memory requirements for various loading configurations when loading the single-channel sample set (Chancel samples only). Note that memory requirements are significantly reduced if the tremulant affected samples are not loaded.
* 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 50878 MB of RAM. It is of course possible to load just two channels (eg Chancel and Surround only), in which case simply multiply these figures by 2.
