I am having trouble with setting up presets and pages on the device. I can get a few to work but then I get to one where even with the correct PC commands and CC commands it does not control the midi devices. I have to reset the device to factory reset and sometimes it fixes the problem with the initial preset then a preset that was previously functional is not working correctly. Often it will change presets or on off status on midi devices despite there being no commands for that device in the preset. I thought maybe one device was sending PC commands downstream but the problems occur even when I wire directly from the the PBC to a device and this doesn't fix the problem. I have watched videos online and reproduced them exactly and often the unit does not function as it does for users in the video. Any ideas on how to fix this problem?
