I, as well as many friends, am waiting for the TC M model to arrive, which I now have been told will be the end of June. If it works as well as they claim it will I'll be a happy camper. If not, it goes back and I will continue to use the Digitech VR until something better comes along.
Yamaha's onboard vocal processor has always been marginal at best, however, there are a few performers that really get a lot out of this part of the keyboard. If you have the opportunity to visit www.psrtutorial.com
and check out the Articles section for the VH processor that was posted you will find that it can be effectively used for live performances. However, you must follow Dan's instructions to the letter. The same holds true with most other keyboards as well.
