Keith,

I experienced the same thing earlier this week and posted thread "Silence is NOT golden" where some of my songs would sound and others did not. Problem....ALL my instrument volumes for those particular songs were set to zero, whereas you only had one instrument set to zero.

I called it my "short between the headset" moment.

Live and learn man. The real good outcome to all of this here is that you (like me) posted the solution to our problems so that others may learn from our mistakes--uh our learning experiences.

All the best,

Mark
