IPC and Hog3pc midi show control??

Scott, what exactly are you finding to be the problem in this setup? This feature was not dropped.

I use USB Midi drive at Hog3pc .The IPC connect both midi in and midi out.I setting up USB midi drive input and output at Hog3pc .And log in Hog3pc again . Both two select MSC in and MSC out.But both two can not tracking backup. I check IPC Midi pilot lamp is work.

Let's simplify the setup here. Turn on MSC out on your Hog3 in the console settings window and turn off MSC in. Then attach a Midi cable from the output of the H3 Console to the input of the Midi device you are using for Hog3PC.

Then go into the control panel of Hog3PC and look under the midi tab and make sure the midi input device selected matches the midi in for the device you are using. Don't select anything for midi output.

Then go into the console settings window for your Hog3PC system and ensure that MSC input is turned on and MSC output is turned off.

Now MSC should be talking from Hog3 to your Hog3PC. Remember that MSC is not aware of what is on the other console so the list and cue numbers need to align exactly in order for playback to work.
