Henk, Sounds like a fun project. I have run into some other folks using the Kolor Eyes player as well.
I may have just the thing for your new player. I have been working for a while on a new ambisonic library I'm calling VVSDK. It does all the things you need, rotate, decode, binaural, and can include my latest A to B-Format conversion code. Early versions are already in use in the VR and acoustic measurement communities and I use the same library as the back end for my own new plugins. All this and more should be generally available as soon as I can do the tedious bits like choosing license types, upgrading websites, etc., but I am ready to talk about individual projects such as yours immediately.
