Yes, they are Dan, but I must say, you really made the most of the built in harmonizer...the best I've heard.

As for controlled environment, I suppose it would be similar to the situation most arranger users would be in, as after all, arrangers are primarily "home" keyboards and would be generally not be subjected to the demands of "live" stage use.

I've passed your tips on to the head guys at Yamaha Canada and they were quite pleased with your ideas.

You do fine work.
