Playback for congregational singing. 2015-07-08 07:46 pm I'm not merely interested in the sound of the playback, but the visual presentation. I and my grandsons have entered perhaps a hundred popular hymns, but playing them back at the church meetings we have has been simply too difficult to achieve. Can anyone help me? Having to use a windows computer to do it can be difficult, but if I have to, I will. Anyone had experience?
