Can someone briefly explain how MIDIPlugin is supposed to work?
In the code for SimpleMIDIPort I see the following method.
primMIDIOpenPort: portNum readSemaIndex: readSemaIndex interfaceClockRate: interfaceClockRate "Open the given MIDI port. If non-zero, readSemaIndex specifies the index in the external objects array of a semaphore to be signalled when incoming MIDI data is available. Not all platforms support signalling the read semaphore. InterfaceClockRate specifies the clock rate of the external MIDI interface adaptor on Macintosh computers; it is ignored on other platforms."
<primitive: 'primitiveMIDIOpenPort' module: 'MIDIPlugin'> self primitiveFailed.
I'm guessing that the line "<primitive: 'primitiveMIDIOpenPort' module: 'MIDIPlugin'> self" is call to something external to the current squeak image.
When I try to execute the primMIDIOpenPort method I get a "primitivefailed" error message. Is this because my current image can't find the external resource?
I'm running Ubuntu 7.04, and in the Squeak directory there is file called "SqueakPlugin.image". I tried copying that to same directory with my squeak image file, but it doesn't help. Am I supposed to somehow load the plugin into my image before invoking the method?
Or do I have to compile my own VM with the MIDIPlugin source code to get this working?

Until very recently the Unix VM did not support the MIDI plugin. You need to build the VM from the latest sources in the subversion repository.

I have built squeak from a recent svn version, and in fact I have MIDIPlugin in my /lib/squeak/3.9-10 directory.
But how can I test it?
I can't see any midi port from alsa when squeak is running.

BTW: Under linux you probably have to load the kernel module manually.

SimpleMIDIPort midiIsSupported returns true.
As I wrote in the squeakaudio list, I succesfully got midi out working with:
SimpleMIDIPort openDefault
At least, I can see the out port from outside, but I haven't tested it yet.
MIDI input, instead,seems unsupported:
SimpleMIDIPort inputPortNumFromUser returns nil.
I regularly use MIDI applications on Linux. All modules are there for sure.
