Hi there Heather and Anthony.
Thanks for your kind messages of support and encouragement. My first dumb question is how do I get from a performance on the PR604 using MSA and all that stuff plus my own playing to an MP3 file of the complete performance on my computer? I have just found out that when I use easy record and save to disk as a MIDI file, all that is saved as far as the computer is concerned is my playing - none of the backing or rhythm, which is all recalled when I play back the disk on the PR604.
My second dumb question is why the Technotes disks specially mentioned as being suitable for the PR604 cannot be played direct - I get an error messaage - but have to be loaded. Leo.
