Hi @gsenna, I’m just wondering about how best to do this. Have you contributed those opcodes to Csound? If we merge now we will get stuck because the only people with access to that version of Csound will be those who build it themselves. On Linux this is fine. And I guess on Windows it’s Ok too as I can build there. But I’ll probably have to if-def stuff on OSX to stop any errors? What do you think?
