Hello, I'm working on a Csound project where I want to be able to reroute the outputs of different instruments running in realtime, using a FLTK interface. For audio outputs it's easy since the zak channel can be changed at k rate but the problem I have is with fsigs. Beside using a series of if-statements to check where to put the final output and global fsig variables, I don't have any other idea for doing this. Is there a more CPU efficient and simpler way of doing it that I'm missing? It's a fsig zak system a good request? Thanks, Hector Centeno
