Both my studios are listening on channel 2, so when I give commands, they both hear me.

To change the channel for a studio:

1. Right click on your studio control box and select EDIT
2. Click on the CONTENTS tab.
3. Double-click the Settings notecard to open it.
4. Edit the line for the channel by replacing the 2 with another channel.
5. Save the notecard and close it.
6. Click your control box an select Maintenance > Reset
7. Your studio will now be listening on the new channel.
