MIDI Virtual Sources and Destinations

[Badsheep]

Hello,

I'm currently trying to write a script to send MIDI commands (control change) to an external application.
I'm a beginner and I'm a bit lost.

The external application (Max, from Cycling 74) creates automatically 2 virtuals MIDI outputs ("From Max 1" and "From Max 2") and 2 virtual MIDI inputs ("To Max 1" and "To Max 2").

I know I need to send midi command to "To Max 1".
But I don't know how to access to that virtual MIDI canal in Hammerspoon...

When I type in the console hs.inspect(hs.midi.virtualSources()), I get { "from Max 1", "from Max 2" }.

But has its names says, these are Sources, no Destinations.
Can I access to MIDI destinations ?
Thanks.

I found a workaround.
I created a midi virtual canal in "gestionnaire IAC" (sorry it's the French name... you know what I mean, the natives midi utility in Mac OS). It's seen as a "device" (not a virtual source) :

hs.inspect(hs.midi.devices())
{ "Réseau", "Gestionnaire IAC", "Bluetooth" }

I set that Midi port to the input of Max, and then I can send some commands using :

toMax = hs.midi.new(hs.midi.devices()[2])
toMax:sendCommand("controlChange", {
["controllerNumber"] = 4,
["controllerValue"] = 11111111111111,
["channel"] = 0,
})

And it works :)

Still that would be nice to add the ability to see the Midi Virtual Destinations in the hs.midi API.
I'll do a Feature Request.
Thanks to all the contributors of Hammerspoon and all the API, it's really wonderful.

I'll have to have a proper think about this at some point. I do remember with CommandPost, I needed to some funky things with IAC to work around some problems too.

FWIW - hs.midi is basically just a wrapper for MIKMIDI.

Hi there!
There is news looking for a solution see the Midi Virtual Destinations in the hs.midi API?
