music for ondes martenot?

Hi, I am looking for a book of pieces and exercises for an Ondes Martenot student (analogue systems version). It doesn't have to be specifically for the Ondes-- I doubt something like that exists-- but perhaps a method book for some other instrument would be appropriate, such as violin, or maybe even theremin??

WOW, I actually found something! First an interesting thing, the Martenot family has a website: martenot.com, and on there the reference some method books for the Ondes. One by Maurice Martenot himself, and others by Loriod. http://martenot.com/article.php3?id_article=53

AND you can web-order them here!: www.alphonseleduc.eu

Here's also the link to the Martenot players association.
They have referenced every books, Cds...
