@ TimR.
Thank you for telling me what is wrong with my singing. If only I had known that all I needed to do was to sing with passion, I wouldn't have wasted the last 20 years behind a microphone!
Trust me, it is very, very hard to manage vocal synth effects either by way of a vocoder and/or effect patches while playing bass and singing at the same time. Obviously, for the Geddy Lees among us, that is less true. It could be that you are one, in which case I apologise.
