Music Shield Stopping Recording

Hello, I have been trying to programmatically STOP the music shield from recording rather than having to physically press the play/pause button to stop it.
I tried setting the “stopRecording” variable to “1” with no success. Is there any way to do this?

Thank you.

Sorry for the inconvenience brought.

After he finish that,We will upload it to the WIKI.
