Dead Link

[bo2]

I did an update to fix an issue on the Sylphyo that's been recurring -- when i go from Bb to C, the C jumps two octaves from a Bb3 to C5. The C does the same thing in each octave

The update didn't fix the issue.

In addition, the Link wouldn't go on again. The settings show the receiver device as greyed out.

Is there anything to be done? Or should I just return it?

Thanks
Barbara
