Leading oboists in Australia and around the world are using the ‘ORTUSO OCTAVE KEY INSERT’

 If you are tired of dealing with octave key water problems read on.

Oboist John DeJarnatt - Seattle Symphony Orchestra
“I still can’t believe that I have gone through an entire Seattle winter without a single problem with my octave key. I think that Loreč should use these as standard equipment. Congratulations Joseph!
Richard Boaden - Victoria, Australia
"Your inserts have made a major change to my oboe, and immeasurably increased my enjoyment in playing it. I am very grateful"
Ernesto Lestón - Montevideo, Uruguay
"I received and installed the octave inserts, then went for six performances of the opera “Il Trovatore” (3 and half hours each) with my 11 years old Royal oboe without a single problem with my octave keys in the cold and humid winter here in Uruguay, this is amazing, the only word that comes to my mind is thanks"
Vicki Philipson - Melbourne, Australia
“Jo’s inserts completely solved the problem I was having with continual water in  the octave keys of my Marigaux. It was so great not having to worry anymore and to just concentrate on playing the music”
Simon Emes - Malaysian Philharmonic Orchestra
I would just like to say that since you fixed my octave box problem last September right before playing Schumann 3 Romances in Australia, I have experienced water in the second octave box only twice under orchestra conditions. Now it's the end of February 2012. After a superficial cigarette paper and NO blowing, it disappeared and never returned on both occasions. At DFP we play in a super cold air conditioned hall. ( approx 19 deg C). I am stunned and so are my colleague by the sudden turn of events. I went to Singapore recently and played Alpine Symphony to the disbelief of the other beleaguered players in the section there.
Bottom line is, it works. Spectacularly. 
Try it or ruin another few of your years filled with caution and disbelief! It works.
Thank you Joe. I'm glad I trusted my instincts!       

I still remember how worried I was just before the start of the Beethoven symphony no.7, not knowing if the opening 'A' was going to sound clean, and how often it did not ring as truly as it should have because of water in that tiny infamous hole. Similarly, waiting for that crucial solo entry in the third movement of Tchaik's 4th at the end of the pizzicato, the memories go on and on.

You may recall an article by myself and dear colleague Alan Greenlees published in the Double Reed (vol. 11, No. 2) in which we put forward a technique for ‘Combating Octave Key Water in Oboes’. For those of you who may have not had the opportunity to read the article I will briefly explain how I went about trying to solve this common problem with which all oboists face. However, I must point out that much re-designing and refinements have taken place since the original submission.

I conducted investigations about the possibility of replacing the metal insert using a non-metal type of material which has greater temperature co-efficiency and viscosity rating than brass. In addition, I concluded that vital structural changes to the insert had to be implemented in order to make the insert more water-friendly.

The material I chose for the job is extremely stable when subjected to great temperature changes, therefore, condensation is eliminated. Another added bonus is that, because of its high viscosity characteristic, this material is 100% water repellent, if water finds its way up the insert it easily blows out through the tiny hole whilst playing.

I have eradicated the water problem in my oboes. It gives me great comfort knowing that all will be fine whenever I have to play past middle D.
