Hi, aah that is unfortunate, I didn't realise there is no way to output to a file, I will contact the developer and ask if there is a way to do this, or if he might be interested in implementing such a feature, as if it were possible to integrate support for it into the build system and rbutil, I think it would really expand the possibilities for building voices.
so is the only question I need to ask is it possible to output to a file? is there anything else you would need to know?
