distarry, Thank you for checking that out for me. I will do a re-install of OS ver 2.01. and check the board again. Everything else is working fine. This is my first experience with using a vocal harmoniser as my Roland EM2000 does not have one. I am pleased that I can reduce my terrible voice and just have the harmony coming through. If you have any experience of vocal harmoniser settings, throw them at me.
