Send a Midi Note to a Midi Hub

Hello
I need to send a Midi signal from Unity to a Midi Hub connected to the PC that distributes note to other pc to gather actions (To be specific, it connects via USB to a Midi Hub that sends the signal to a Dimmer that moves some engines)
Is there any plugin that makes that possible?

Regards

You might have a look at MIDI Unified:

I have used it to play MIDI notes on-command by selecting its C# Synth to use the default Windows MIDI synth - which I have set to use the CoolSoft Virtual MIDI Synth. CoolSoft uses soundfonts, which can be General MIDI soundfonts (and there are some free, big, really good ones around) or soundfonts you create with your own sound samples using something like PolyPhone.
