Hi, is anyone else having any trouble getting the auto harmonizer and arpeggiator button to work. When I press the button it shows the auto harmonizer but it doesn't do anything. I've tried all the different settings for it and nothing. Then I try to change to arpeggiator in the function section and can't get that to work. The manual regarding the function button is a bit confusing. Any suggestions? Is it me or is it a malfunction in the keyboard. Thanks so much for any assistance. I really want this to work.
