The Johannus Revolution

Chiff Dynamics
Blowing an organ pipe creates an effect known as chiff. This forms an essential component of the overall sound. In most electronic organs chiff is created by computer simulation. The result ranges from poor to reasonable. In Johannus organs, however, the original recording of organ pipes is used. Each time when a different key is pressed, the fundamental tone is preceded by chiff. When the same key of a pipe organ is pressed in quick succession, the air column remains inside the pipe. This causes part of the chiff to be lost, dependent on the speed of the note repetition. Although this effect is typical of a pipe organ, it was always lacking in pipeless digital organs, because it was not technically feasible. Johannus Research proudly presents a new breakthrough in organ technology. From now on it is possible to mirror the pipe organ effect: a tremendous step forward (patents pending).

Easy Menu
Large organs are seldom simple to operate. The mind of the user boggles at the sheer number of technical possibilities of modern computer technology. The Johannus Opus, Sweelinck and Rembrandt series are favourable exceptions. Johannus Research have developed an accessible system bringing you the advantages of this fantastic technology: Easy Menu. Experience the possibilities and convenience of this menu, developed by organists for organists.

pipeLIFE™ Tuning
All organists know that the musical beauty of a good pipe organ is unsurpassed. Every pipe differs slightly in response, depending on a number of variables. For example, Johannus previously introduced its unique wind pressure activity, which recreates the slight detuning of pipes when larger chords are played. Of course, the degree of pitch sag depends on wind system design, number of keys and type of stops used, with the effect greater on higher pitched pipes and less on larger ones. The depth can be adjusted to a real ‘wind sagging’
pipe organ impression. A great accomplishment in itself, but JOHANNUS has now gone even further! Now the Johannus research team has recreated another unique pipe organ characteristic called pipeLIFE™ Tuning. The tuning of a pipe is seldom exactly the same, even when played twice in succession. The pipes’ pitch is influenced by temperature, wind in the chest, physical layout of pipe ranks as well as which keys are played simultaneously. Pipes in physical and acoustical proximity to one another infl uence each other’s pitch; this
phenomenon is often referred to as ‘drawing’ by professional organ tuners. Johannus pipeLIFE™ Tuning recreates this phenomenon and employs these properties with amazing realism and clarity to create the ultimate pipe-like experience. Another FIRST from JOHANNUS!

Physiological Tone Control
When an organist closes the swell box of a pipe organ, the volume gradually decreases, especially of the higher frequencies. This creates a sonorous sound and organ playing assumes a typical, modest character. Thanks to a stunning breakthrough of Johannus Research you will fi nd this characteristic now in all our organs (patents pending).

Masterful Cabinetry
Dutch Pipe organs of past centuries distinguished themselves for great craftsmanship. That is not only audible - in the sound of organs from that time - but also visible. Breathtaking architecture and the unrivalled mastery of the cabinet-makers are characteristic of the Golden Age. The magnificent panelled cabinets of the new Sweelinck and Rembrandt organs recall that era. And again it is a matter of an inspiring sound combined with
masterful cabinetry. Here Johannus is unique and lonely at the pinnacle!

2.1 Surround Acoustics
An entirely new trend is 2.1 Surround Acoustics. Every Sweelinck and Rembrandt organ can now be extended with this system. With only two additional wonderful design speakers a fantastic three dimensional sound is realized.

Real Time Sampling
It is the talk of the town, but actually what is it? At bottom Real Time Sampling is nothing but a system that reproduces original recordings of famous pipe organs per key. Well, you will say, everyone offers exactly that. Just a moment, that is not the case. Usually a recording of a pipe organ is used merely as an example. This recording is known as a sample (hence everyone’s assertion that they build Sampling organs). This sample is not applied in the organ. It is made into a computer simulation. That is a piece of software - a complex digital formula - which is incorporated in the organ. You hear a ‘sound-alike’, not the real thing. It resembles it, but this algorithm is still a poor imitation. Thanks to Real Time Sampling a Johannus organ sounds exactly like a genuine pipe organ.

Romantic, Symphonic and Baroque
The organ culture on the European continent can be divided into three main streams: Romantic, Symphonic and Baroque. For the true organ lover these styles are incompatible. Each style in the organ literature requires its own specifi cation and timbre. Johannus Research have succeeded in building three organs into one. Simply pressing a button changes all the stops of your organ from a Baroque to a Symphonic or Romantic organ. This fantastic breakthrough in the organ world is a dream come true for every organist (patents pending).

Classical, Solo, Hymn and Trio
The choice of music determines which stops an organist will need. This is not the full picture, however, for the way in which he wishes to combine these stops usually differs a lot. For liturgical works a broad sonorous sound is mostly considered appropriate. Trios and more light-hearted literature require clear, transparant contrasts. For a Trumpet Tune we want a speaking trumpet. Incompatible wishes? Not any more! Johannus Research have invented the answer to this issue. Now you have four intonations at your disposal. Just press the button to switch from Classical to Solo, Hymn or Trio (patents pending).

12 different organs?
The magnicent variety of the organ literature requires organs diverging in sound, intonation and tonal quality. The new Johannus Opus, Sweelinck and Rembrandt organs offer the organ lover three basic varieties: Baroque, Symphonic and Romantic, each of which has as many as four different intonations: Classical, Solo, Hymn and Trio. Twelve organs in all. Get ready for an overwhelming musical experience (patents pending).

Demo Songs
To properly demonstrate the new Johannus organs, we have recorded a number of demo songs. These can be comfortably reproduced, enabling you to appreciate the differences between the organ styles and the various intonations.

An electronic piano has a key dependent touch. A number of organ lovers have requested this to be incorporated in Johannus organs. We have honoured this request, so that each owner of a new Johannus organ can operate external keyboards and sound modules via MIDI. Playing the piano on a Johannus surely enhances your musical delight.

Multi Channel Audio System
The practically perfect reproduction of authentic pipe organ sound, as found in Johannus organs, would not make any sense with a poor audio system. Here Johannus have built up a tremendous reputation. With the introduction of X.I AUDIO the sound quality has been further improved.

A Johannus at home

The philosophy behind our audio system is quite simple. Amplification with a microphone does not turn a solo singer into a choir. This would require a good many extra singers. If we want a lot of volume, we do not ask the choristers to sing very loud, but we employ a larger choir. Johannus operates along the same lines. The Studio, for example, is fi tted with 3 amplifi ers (2.1 AUDIO), not 1 or 2, as is customary. This results in a broad ensemble. Larger dispositions as in the Opus require 4 amplifiers, whereas the Sweelinck utilizes even 5 to 7 amplifiers (4.1 and 6.1 AUDIO).

A Johannus as a Church Organ or Concert Organ
To be at its best, an organ must have acoustic power equal to its task. For this reason a Rembrandt organ contains at least 7 to 9 (6.1 and 8.1 AUDIO) amplifier channels. We always recommend applying as many audio channels as possible. This not only avoids audio fatigue, but also unbalanced partition of the volume. You surely would not want the organ to sound too loud nearby and too soft farther away. Therefore we avoid using loud volume together with only 2, 3 or 4 channels. We, at Johannus, prefer multiple audio channels (acoustic power). This way the organ always
remains jubilant, also as full organ.

Rembrandt Concert Organ series
In the Rembrandt the Easy Menu also provides 12 different temperaments: Equal, Kirnberger II, Kirnberger III, Meantone 1/6, Meantone 1/5, Meantone 1/4, Neidhardt III, Pythagoras, Valotti, Werckmeister III, Young II and Custom. Next to that the Rembrandt organs give you 7 Super Solos at the tip of your fi ngers. The ultimate in Real time sampled quality of orchestral instruments that sound like a life artist plays next to you! In addition Easy Menu gives access to another 40 wood, brass, string, percussion and organ voices:
