I really love the TC, but as DNJ said it is somewhat quirky. Additionally, I went through the procedure outlined to determine which OS mine has and when I hold down those buttons nothing is displayed on the screen. That slight delay is also a problem as well. The vocal harmony quality, however, is a notch above the VR, but just one notch. I may also switch back to the VR as well--what the hell, I have three of them.

BTW: Nearly all of the Yamaha keyboards transmit the information via channel 2 and the VR must be set to channel 2 in order to receive the information.

Cheers,
