I currently compose an ambisonic piece in Csound using Pierre Lecomte's tools created in Faust : ambitools - ambitools
There are open source : Releases - ambitools - Sekisushai's Git
Actually with the "faust2csound" command, I can use these powerfull tools as opcodes for a 22.2 sound system.
In my opinion it could make sense to use it in Csound...
What do you thing about that?
