Grant,
I'm going to burn that on my CD. I need some clarification...

1) Is that preset named 'Meditation 'Deep'' ?
2) How long should that preset be ? You said I have to go down to 30mins and stay there for 30mins. Does that preset take care all of these or I have to specify the pitch myself?
3) Isn't it boring listening to that preset 1 hour? Can I merge it with rock music?

thanks.
