Thanks for all the helpful replies.
Donny - you're right on about that SMF. We usually play along live and that masks a lot of the stuffiness. I've used styles live before that do have a better feel. This is a SMF, but I would be open to one with a better feel.
Zuki - I did not touch the keyboard during the song. The harmonies were automatically generated by the harmonizer. I will record some more songs soon.
saimg - The midi was played using the DC5's LIVE cover; it is slightly different than the original instruments. For the harmonies I used the Singer mode with Ensemble harmony. The Ensenble was set to Soul. I faded that harmonies in and out with the knob; I found that quicker and easier than switching the harmonies on/off. Also, keeping the harmonies alive helped me mix the volume and intensity.
This would be a lot of work on a live job, and would probably interfere with playing live keyboard. I'll have to experiment some more and see how effective I can be doing the singing, harmonizing and keyboarding all at the same time. In any case, it sure is FUN!!!
