Dereux Recording

This mark is hlas trs more known in France as the disappearance -1979 - its inventor Adolphe Jean Dereux, led the socity closed in 1982. the inventor has cre in the first time - 1950 1960 the "Paris of the organ Socit electrostatic" and in the socity deuxime time IROC (International Organ Recording Company). It with this Jean Adolphe dernire Dereux will therefore invent built, marketed for 30 years serving the organ lectronique.Si Dereux did not invent the principle (the invention in the making in the silent ann 're thirty), he has perfected a system that greatly making the most original and an old couraging rve for many organizations of this era. Remember the adventure and its HAMMOND gnial inventor who also built an ersatz organ that will delight jazz musicians ...

idegnratrice is the analog recording sounds rels of organ pipes, they both read by an analog memory called "electrostatic".
reading offered no latency.

The principle silent simple. It is based on the fact that two fixed disks in vis - vis, and are a serious PROCD electrochemical acid bath-and-serve electrolysis mmoriser waveforms sounds. In the middle of the discs, there is a mobile disc called "reader".

This is the one who dlivre sound information via the pre amplifier. The great Discoveries of this principle and it's from a rel registered and this is his return through his image Prior to laboratory analysis using an oscilloscope.
Somehow, the sound becomes image and this is the original translation of the initial call be reproduced by amplification. Not surprising ...

Regarding the organization of the composition of the organ, the inventor uses the principle of organizational units. Dereux has manufactured the ranks of pipes instead of games rels. Then He arpartis to refine the composition of the organ. In résumé he only had to eight rows of pipes couraging a composition closer to 25 games. For this, a cr Dereux switch to gnral rpart sounds depending on the composition requires.

The instrument consists of two keyboards (CITL Grand Orgue +) 60 32 Notes 1 pdalier notes. It is fully polyphonic (a rarity in the field of classical electronic organ). There a volume pedals gnral for the instrument. The couplings are conventional (REC / DC: GO / PED: REC / GO). The quality of sound samples is good and trs s'altre do not in time. There is no need to agree. The only maintenance is to change the power tubes and some electrolytic capacitors filter when it is fatigus.
Production is estimated between 3000 and 4000 instruments.

UTILIZATION

JA Dereux a prvu using the instrument for the concert or the study. Two MODELS dominate production:
<ul>
Studio (amplification and speaker cabinet Intgr to 45 W)

<ul>
Church (100 W Cabinet spar)
</ul>
In addition, he has had two distinct fabrications: <ol>
the first tubes in the 60&#39;s.
the 2nd in the 70 transistors.
</ol> Similarly, transistors and Resistors The models were mtalliques conus demand for Steinway Germany. They thus dclinent 2 MODELS:
<ul>
- 2G (2 channels)
</ul>
<ul>
- 4G (4 channels) a variant of the 4G + (MODEL trs rare)
</ul>

SOUNDS

The sounds are excellent in terms of years of construction (years 60 and 70). (On) organist will easily adapt this instrument. the resemblance to an instrument of classical and mprendre it.

With the exception of transient sounds unsupported by the Sampling Sharga, you will find the sound of an organ pipe. (Http://62.163.27.126/parie/?dereux=4&home=9)

OVERALL OPINION

<div><img alt="" /></div>
I possde the instrument for 15 years. He does fvrier manufactured in 1965. There was no major failure not on mine, the block gnrateur is healthy. The cblage well RALIS held up over time.

I would add that each instrument NCESS working hours Fully manual. The electronic uses only discrete components (Resistors, capacitors, lamps ECC83, EL 34 ... etc). In the era, it was an electrician from village to intervene! JA. Dereux is a pioneer, he foresaw the future of sampling. When Allen invented the organ numrique memory in 1972, it was turning a new page. In the era, it was 7 times less expensive than its cousin pipes.

So I recommend its purchase if the instrument is "fresh" the passions of rparateurs maintain happy.

In conclusion, it was a great technical and musical adventure sadly forgotten today. Must reconnatre the confidentiality of this production does not aid its reputable.

PS: the organs are not Dereux MIDI is no date of MIDI kit. However, we can consider the use of contacts THEY couraging but you have a lot of work cblage.
