Sorry about the upload issue, I’ve updated the config to allow new users to post files.
You should now be able to attach the preset here.
The SC REMAP pipe might be the cause of this issue, we’ll fix it.
I think there’s another way to workaround this state - you could try making the Midihub’s button send ‘all notes off’ message (configure it in Device->Settings), then if you hold the button down for a second or so, it will send to the selected destination port an ‘all notes off’ MIDI messages to all 16 channels, it should make any stuck notes to be reset.
As for MIDI OX - you have to select which input and output MIDI devices should be opened in Options->MIDI Devices (if you get an error opening some device, usually that’s because it’s already open in some other software). Then in View->Port Routings you will see the open ports, you may make connections between the in and out ports to forward MIDI data between them. (very useful if you want to use USB MIDI controllers with Midihub, but the same should be possible to do in DAWs too)
The Output Monitor is always open in MIDI OX, and the input monitor can be opened via View->Input Monitor.
