Sunny,
Have you gotten to sleep yet?
Sunny called me at home this morning
(MY morning ... it was 8PM in India)
and we had a brief conversation about the harmonizer and noise, like Jill has beeen posting about. Sunny said that the EQ reduces the annoyance, and that just solidifies my opinion that the trouble is effects-based. The mic section of the 2100 is way better than average, and as such - you need to have it adjusted correctly for optimal sound quality. Compressors, gates, and EQ can all screw up a mix very easily.
Make sure the kb is initialized to full factory settings, and then tweak it till you get the personal touch that sounds best for you.
It was a great pleasure to hear from a new friend so far away. Thanx for the call, Sunny...and best of luck with your new purchase.
I realy envy anyone who has mastered more than their native language. Sunny's English was better than some people I deal with everyday, here in the states ! Thanx again for the personal call, my friend !
