I have worked extensively with Ambisonic (Higher Orders ) in conjunction with Kyma, not in Kyma itself. However I am currently together with Christian Vogel and Gustav Scholda of NeverEngineLabs developing tools for doing Ambisonic ( 1st order 3D and up to 3rd order 2D) in Kyma. We have developedgood sounding and working encoders and decoders, but we are currently re-designing them to be much more flexible so stay tuned!
