You just input the melody and chords then select the style of music you want, and the program generates the midi in that style. You can experiment with different styles until you get the right sound. I have also used some third party BIAB styles created by Norton Music . They are excellent. There are so many songs.
Every group has different musical talent.
Just choose the songs that seem most fitting for your group. Praise You My Father . There are several Christmas songs available. See the Christmas Page for a list of these. I have also started a Children's Page with songs written for kids and an Easter Page with songs about the death and resurrection of our Lord.
