OK, here's my step-by-step.
Record songs on USB flash drive on my Casio Privia PX-780m.
Plug flash drive into computer.
Open Roxio Creator.
Select 'Audio CD'.
Select 'Add Music'.
Music files screen displays:
Look in: Audio
Easy Audio CD screen displays:
Click orange button lower right screen to burn.
With volume turned to maximum, can hardly hear songs. Can't find anything in Casio manual for volume control.
Thanks for any help you can give me.
