creating extra virtual midi port

January 10, 2008 | 2:42 pm

Hello.

I’m trying to create an extra virtual midi output port, which other applications (Ableton Live) can see on the same computer (Mac 10.4).

I’ve tried using the [;#SM createoutport myvirtualport augraph] message, and MIDITester can see this new port, but no other applications on my Mac can.

Does anyone have any experience of this and can suggest how to get it working?

Thanks a lot.

Network in Audio Midi Setup. Are these still called IAC’s?

Sorry, I should have looked at Audio Midi Setup. You want the IAC driver.
Network is for setting up midi between computers on a network.

Thanks, Gary. I had a fiddle with Audio MIDI setup, but to no avail.

I’ll keeping plugging away with the Max Virtual MIDI Port.

Navigate as follows:

Audio MIDI Setup
MIDI Devices
IAC Driver
More Information
Ports
Add Port
Edit port name
Set midi I/O channels
Apply

After this the port you added and named should show up in Max and in the
other application (Ableton) if it supports IAC I/O. I use this all the time
with Kontakt and Reaktor.

Just be aware that an IAC bus is non-directional (2-way in a single bus), so you must be careful not to send and receive using the same IAC bus in one app, or you run the risk of creating a runaway MIDI feedback loop. Logic is especially twitchy in this respect BTW. The IAC bus timing can also be fairly jittery.

But you’re almost there with creating the built-in virtual port. The last item in the message is the driver to use – you don’t want "augraph" (the Mac OS softsynth driver), you want "coremidi", which other apps will see:

;#SM createoutport myvirtualport coremidi

are you talking about something like midi ox?

It would be helpful in future if things like this could be labeled windows
only.

Thanks a lot everyone. This has really helped!

As soon as I changed the driver to coremidi, Ableton Live could see it. The driver name must be case sensitive, because when i tried CoreMIDI (as documented in the official documentation!!!), it didn’t work.

Thanks again!
