RX1602 Line Mixer Suggestion

With all the synths Behringer releases it would be absolutely wonderful if there was any easy and affordable way to get them connected and recorded into the computer. I would be thrilled if Behringer would do a version of the RX1602 Line Mixer with USB to act as an audio interface to the computer. Even better it would be great to see the inputs expanded for synths…maybe 8-12 mono inputs for the many mono synths and another 8-12 stereo for stereo synths. As far as i’m aware no one has a line mixer with USB and i’ve been waiting for something like that for years now.
