Hello, Thank you Richard Dobson and sorry for my mistake... You wrote:"I have always understood it was not possible to add an ambisonic opcode, as such, into Csound, as it is still a proprietary system." If you mean that it is not possible to do it for legal reasons, why do people are still continuing to compile the CSound file with new opcodes (Cf Gabriel Maldonaldo, (hello and thanks to you))? Must there be a special autorisation to "diffuse" THE Csound file with your own opcodes? There are things (a lot) that I do not understand. Bye Bye.
