Anyone know why Adobe Audition will not allow me to select inputs 3-16 on my Tascam US-1641. I have set up the new Tascam unit but when I try to view my input selection in Audition, it only shows the Tascam unit as a whole. I can record using channels 1 and 2, and it will play back on the monitor outputs, but nothing else. I am not a fan of CuBase, but since it came with the Tascam unit, I installed it on my computer as well thinking that Audition was the problem. CuBase showed channels 3-16 as "inactive" whatever that means. My PC meets or exceeds the specs required by Tascam for this unit. I fired off an e-mail to the support center of Tascam but have not got a reply. I wanted to see of anyone else has had this problem and hopefully get some advise. Thanks in advance for any help.
