Came across this post about IO on gearslutz.
"16-bit 44.1k in the current form. We downsampled to 44.1k 16bit for a smaller download package. So there is potential to create a 24bit version with more advanced features if there is a demand for that. Please contact us, or post on the forums to let us know."
I'd definitely be interested in a 24 bit version. Also, are GPO, JABB, and World 16 bit as well?
