What
makes Veritas unique …
• The Technology
Veritas Organs employ a
custom version of the Musicom digital synthesis system, together with
software unique to Veritas. This system was originally conceived at
Bradford University some 25 years ago, and since then has been developed
to become the most technically advanced and sophisticated digital pipe
synthesis system available anywhere. It is made available to a very
few, carefully selected organ builders. It is the skills and experience
of the Tonal Director and his colleagues that ultimately determines
the quality and personality of the final instrument, in just the same
way as would be the case with a real pipe organ. Our Tonal Director
is Graham Blyth, who has more than 17 years experience voicing with
this technology and has been intimately involved with its development.
He is the most experienced and skilled exponent of the system today.
Graham is an organ recitalist of international repute, and has given
concerts at the Madeleine (Paris), Vangede Kirk (Copenhagen), St. Bonifaz
Basilica (Munich), St. Thomas’s (New York) and Grace Cathedral
(San Francisco). Graham is also highly regarded in the world of professional
audio, having founded Soundcraft 30 years ago. This experience is also
reflected in the audio quality of our organs.
• Why not
use sampling?
Sampled organs use recordings
made in sterile conditions that take no account of the behavior of real
pipes when others are sounding nearby and sharing the same wind supply.
Veritas’ Digital Pipe Modeling system not only recreates the sound
of the actual physical pipe, it also takes into account the subtle but
very noticeable effect of other digital voices played on the same digital
wind chest. On sample based organs, listening to individual stops on
a note by note basis can be quite realistic; however, adding more stops
and notes in the harmony produces either a sterile sound or an artificially
induced “wishy washy” effect. This is even more noticeable
when you begin to add reeds and mixtures. Why is this? Sampled organs
replay recordings of pipes obtained in perfect, sterile conditions,
with no other pipes playing at the same time, a totally unrealistic
situation. The many subtle imperfections of pipes are their very glory.
Our ‘digital pipes’ react to the pipes around them in their
own ‘digital pipe chambers,’ providing this key element
of realism. A pipe organ is a living, breathing instrument and Veritas
organs behave in the same way that real pipe organs do.
• Independent
real-time generation of each note in true pipe manner
In a pipe organ, each note
is generated by the pipe when it is played (in real time, when the key
is pressed). When multiple notes are played, many interactions take
place, as noted above. The Veritas Pipe Modeling System recognizes these
anomalies and subtleties and this produces a realistic and convincing
ensemble.
In other technologies, there
are recorded samples for each rank, sometimes only one for the entire
keyboard, other times several, and when a note is played the recorded
sample is tuned to a different pitch, leading to a sterile and unnatural
sound.
• Dynamic
development of “instabilities” in harmonic structure for
each note
The individual pipes of
a pipe organ do not always produce the identical harmonic character
due to very subtle imperfections in the physical pipes, their interactions
with surrounding pipes and changes in wind demand. A recorded sample,
when tuned to a different pitch, cannot accomplish this dynamic. Our
system’s tone generation system is ‘live’ in that
the normal variations occurring within pipes are dynamically produced.
This is particularly noticeable in ensembles where many different pipes
and notes are interacting with one another.
• Proper development
of wind, chiff and other characteristics for each note
Within pipes, the sound
of air and chiff vary in a non-chromatic manner from one note to the
next. This subtle difference is very noticeable if one listens to a
chiffy Gedeckt, for example. A recorded sample makes the assumption
that wind and chiff vary chromatically and, depending on the number
of recorded samples in a rank, the effect is more or less severe. The
Veritas Pipe Modeling system precisely generates wind and chiff based
on the characteristics of each individual stop and pipe that change
as the scale of the pipe changes throughout its compass.
• Sophisticated
multi-channel audio system
When two electronically
produced organ sounds are summed into the same channel at the same pitch,
such as a Principal 8’ and a Gedeckt 8’, certain harmonics
will alternately increase and decrease in power as you hold the note,
due to the very slow shifting relationship between the two waveforms
caused by minute differences in pitch. This happens only slightly with
real pipes because the multiple reflections reaching the listener override
this addition and subtraction. Therefore, it is important to prevent
stops of a similar pitch from appearing in the same speaker channel
for the same note. The scheme used by Veritas technology extends this
even further. The method preserves the usual C—C# left/right split,
but makes sure that no more than one stop at any pitch ever comes from
the same loudspeaker on any note and that chords played from the same
stop involving the most common intervals, and particularly octaves,
obey this rule. This contributes greatly to the free and open sound
of Veritas organs. A small two-manual organ would generally have a minimum
of twelve to sixteen channels, though less can be used in a home or
small church without sacrificing sound quality by employing technology
developed by Veritas for this purpose.
• Total control
over tonal finishing and voicing
Each characteristic of every
note of every rank can be finished and voiced to suit its environment.
The tonal finishing of a Veritas organ can take several days on site,
during the installation process, just as is done during the installation
of a pipe organ. Our system does not utilize recordings of disparate
pipe organs but, instead, produces a cohesive, musical, dynamic in an
instrument that is truly enjoyable to play and listen to that will satisfy
the most critical listeners for years to come.
• Combination
instruments, with as many pipe ranks as desired
The finest sound to be achieved
is that from real pipes. We all know that electronic organs can do quite
amazing things in reproducing pipe organ sound, but their reason for
existence is owing to budgetary and space considerations faced by many
congregations. With our system, as many ranks of pipes as are desired
can be used in conjunction with the electronics. There are no limitations
as to which ranks or which divisions of the organ they can be employed
in and future needs can be accommodated without undue cost. Our system
can also be used to augment pipe organs, either with just a few ranks
or with entire new divisions.
