Noel and Del,

I also entered a chord progression and generated an 18 bar song using the _GRVYPNO style. Initially I had the same results of rendering without the fades result you experienced.

I inserted nodes to fade each track except the strumming guitar starting at bar 16 and fade to -64 at bar 17 allowing only the strumming guitar to play through bar 18. I did a gain change to -96 with audio effects at bar 16 through bar 18 to mute the drums.

I went to the beginning of the song and for each track I placed a node on the node line just before any audio began playing. I also right clicked each track after doing this procedure and selected the clean all nodes option.

The song then played correctly and also rendered correctly for me.
