Hi Group. I was under the impression that I could run the serial U8 on a stealth port & a USB MT4 all under OS9 and have them behave like ten separate inputs and twelve separate outputs but it's not working. When I create a physical input object it gives 32 ports with U as the prefix and another 32 with P as the prefix but it seems that the first 8 U inputs are for Unitor 8 and the first four of those are doubled by the MT4. Tell it isn't so??? -- ==/==/==/==/==/==/==/==/= Paul Najar Jaminajar Music Production http://www.jaminajar.com.au
