reason:
i messed about with cubase on my cousins computer and i really liked it. not as much as i like my current DAW but, there were a few things i thought were great and that id like to take advantage of via. rewire. especially as im starting to experiment with bouncing midi to audio, chopping it up and doing all that fun stuff with it, i think people call it resampling
now, if nuendo is basically the same thing as cubase with lots of shit for post-processing, than it seems reasonable and id definitely spend my money on it. im just trying to figure out what the fuck it is.
