A new website resource for the Ondioline is coming. "Web page will include: History ~FAQ ~ Misconceptions ~ Photos ~ Sound Files ~ List of Ondioline Users ~ Ondi's Spotted on Sale ~ Who Repairs Ondi's ~ Schematics ~ Tuning Instructions"
Note this is via Dana Countryman who plays with Jean-Jacques Perrey, who's instrument of choice is the Ondioline. I was actually fortunate enough to see the two play live. Jean-Jacques Perrey had his Ondioline and Dana Countryman had a large Synthesizers.com modular. You can see a video from the performance below. A search for Jean-Jacques Perrey will bring up more posts. Definitely worth the time to check out.

Update via Mal in the comments: "There is an excellent DVD that one can purchase called "Life, Laughter & Loops" which features an 80 minute interview with Jean-Jacques Perrey and 60 minutes of never-to-be-seen-again concert footage... all Ondioline, all Moog - Fantastic!!! http://www.jjpdvd.com"
