I am hoping that you include ReWire in version 1.0 but sadly I am not optimistic about this given all the work you have. Perhaps you are not a DAW user so you may not fully appreciate the value of a DAW to a modern composer. A well implemented ReWire connection between your program and Cubase/Nuendo would make a lot of people very happy, especially those who are scoring video and making multimedia & electro-acoustic recordings. Please consider it in the first release!
