On the Switch-6 only the last switch will respond, none of the other switches work. Is the unit broken?
This issue is usually a sign that the cable being used is incorrect. We package the unit with a 'TRS' cable, and this is what should be used in order for the switch to work correctly.
If you use a 'TS' style connector (guitar cable), this cable is not capable of sending all the information required in order for the switch to communicate properly with your device.
