Using my midi foot controller I am sending midi clock and a midi start message to a midi Solutions Beat Indicator with Power Supply. The Beat Indicator does not flash (it should flash in time with the clock) unless I first disconnect then reconnect it's midi cable. If I change the midi clock tempo the Beat Indicator no longer works until i disconnect and reconnect it's midi cable. All other midi devices in my chain react as desired to the midi clock and midi start messages without fail. What could be wrong with the Beat Indicator?
