Hi Jarvis,
I am not sure I fully understand the connections, but my guess is that you relied on the MIDI thru function. It forwards all MIDI messages coming to MIDI IN to the MIDI OUT port. As of version 1.2 the MIDI Thru is a configuration option. It is off by default and it can be enabled by sending a config file to Electra. Please see the topic below to see how to configure it.
Please, let me know if enabling MIDI Thru resolved your issue. If not, I will look at it with you.
Cheers
