AHLBORN - HYMNUS IV
AHLBORN CLASSIC ORGAN
MODEL “HYMNUS IV”
FOREWORD
This instrument has been designed and built with the most advanced SWP (Sampled Wave
Processing) technology, aimed at recalling the characteristic timbre of the classic pipe organ.
The HYMNUS IV has a fantastically natural and flexible sound in that, with each stop, all the notes
in the musical scale are alternately channelled to the left and to the right (C/C sharp) just as in
traditional pipe organs.
A special remote control programmer (INTERACTIVE PROGRAMMER), supplied as equip-
ment, permits the organist to voice the instrument according to his particular musical requirements
and to adjust its sound to suit the acoustics of the surroundings in which it operates. The HYMNUS
IV organ is also supplied with a four-track SEQUENCER and on request, it can be equipped with
a FLOPPY DISK DRIVER which greatly enhances its performance, both for study and in liturgical
use. A special user’s manual is devoted to all the functions of the Remote Control Programmer.
The layout of the console, the stop tablet positions, the combination control, the stop nomenclature,
the touch of the keyboards and pedalboard correspond exactly to those of the most prestigious
modern pipe organs with electric action.
Every organist with a good knowledge of such instruments will appreciate the resources in timbre
and dynamics which the HYMNUS IV offers, and which allow him to play most styles of music.
The following general instructions are meant as mere examples, since the art of organ registration
is closely connected with the sensitivity and culture of each musician, and can be influenced by
environmental and acoustic conditions.
STOPS
Control tabs are placed in a horizontal row above manual I and are divided into three, easily
identifiable sections. From left to right: GRANDE ORGANO I (Great), PEDALE (Pedal) and
RECITATIVO II (Swell).
The tabs are of the light-up type: if the lower half of a tab is pressed, the corresponding stop will be
activated, lighting up the relative LED. Pressing it once again, deactivates the stop and the LED goes
out. Such a system permits a clear visualisation of the stops drawn and correct use of the combination
action.
Tabs are numbered progressively from 1 to 31 above their name. The organist may use this general
number to note down quickly the registrations chosen. The name of the stop is written on the central
part of the tab together with the number of ranks which form it.
The bottom half of the tab shows the conventional pitch of the stop. In each section, stops are
displayed from the lowest to the highest footage. When two stops have the same pitch, they appear
in the order given by the sound “family” to which they belong: Principals (or Foundation), Flutes and
Bourdons, Strings, Mixtures, Undulating stops and Reeds.
This last group is placed on the right hand side of each section, before the Couplers, and their tabs
are marked in red.
