Companion Midi Button Presser

Hi all - it just occurred to me that I could usefully cross-post this here, as well as in the old Faithlife board where I posted it back in April.
I made a quick video describing "Companion Midi Button Presser", a simple (and open source) app I wrote recently to help with automating aspects of our church production environment. It aims to make it simple to control Bitfocus Companion by sending MIDI notes from Proclaim lighting scenes. Companion can in turn control all manner of A/V production equipment.
This is working nicely for us so far (though only a few weeks into using it); I hope it may be useful to other churches too. There are bound to be bugs to discover, and enhancements to make. At present it's Windows-only as I don't have a Mac to hand to test and build on.
