I just received a new MCU Pro and downloaded the Sony white paper which is written for the original MCU. The MCU manual recommends using the USB connection but the white paper says to use midi and says nothing about USB. I can't get the MCU to show up with USB although I have been able to use a BFC2000 in Vegas 7 & Acid 6 with USB using the same connection. I suspect that there may be a defect with the unit I received but I wanted to troubleshoot all possibillities before returning it. So the bottom line question is: will the MCU Pro work with Vegas & Acid using a USB connection or is midi required? Thanks!
