Scott:

The Yammie Vocal Harmonizers are really difficult to work with. I use them all the time to attempt to blend my miserable voice into the song a little better. Usually, at the most inopportune time, I'll get a little "warble" that requires me to either re-cut the entire song or just throw up my hands in disgust. The "Country Girls" back-up appears to be the hardest to control and "Karaoke Mode" seems to be the back-up option that "warbles" the least.

Don Mason advised me a long time ago to reduce the usage of backup on the Yammie and I have tried to cut back as much as the "flavor" of each of my songs would allow.
If only I had access to George Strait!

All my best,

Dave Rice
