I'm trying to open a midi port to receive incoming midi commands and am completely stuck (after a week of trying everything I can think of). I've confirmed that the MIDIPlugin is loaded. I've tried on both Windows XP and MacOS. The only port I have available is this:
MIDI Ports: 0: QuickTime MIDI (out)
Everything I have tried to create a new one has failed in the midi open primitive.
I suspect I'm just being dumb and there is an obvious incantation (hope so anyway).
Thanks so much for any advice you can provide.
John

Hi John,
I am not an expert in this area, but I did get MIDI-in working on Windows. I think you'll need a physical MIDI input device, e.g. if you can borrow a USB (piano) keyboard, or something like a MIDISport box. Squeak just sees what the system sees. I don't believe you'll be able to automagically conjure up a port.
If you evaluate SimpleMIDIPort midiIsSupported, you should get true on Windows, and false on OSX and Linux. So you'll only be able to do MIDI-in on Windows, for the moment.
Craig Latta was planning to port to these OSs- see this thread: http://www.nabble.com/MIDI-support-td13476203.html#a15745241
Craig, any news?
Cheers, ...Stan
The physical device and midi/usb interface are present and working (verified by other software on the system which sees them). So my problem seems to be not knowing how to bind them to a new midi port so it can be used by Squeak.

Hi John.
It's been a while since I've played with MIDI in Squeak, but I just gave it a whirl on Windows XP with a 3.8 image, and it seemed ok.
What do you get when you run:
SimpleMIDIPort inputPortNumFromUser
It should pop up a menu listing all the MIDI inputs that the OS knows about. When you choose a port from the menu, that expression will then return a number, representing the MIDI port you chose. If Squeak isn't aware of any MIDI input ports, the menu won't appear, and the return value will be nil.
The same holds for the method outputPortNumFromUser.
If the menu appears ok, then you ought to be able to create an instance of SimpleMIDIPort something like this:
midiIn := SimpleMIDIPort openOnPortNumber: (SimpleMIDIPort inputPortNumFromUser).
It may be you've already tried all of this to no avail, in which case I'd say this would need to be looked at by someone who knows rather more than me about how MIDI is handled at a low level.

Craig, any news?
I'm planning a 2008-06-20 (solstice) release of Spoon[1], featuring a module system, and a 2008-09-22 (equinox) release of Quoth[2], which I plan to deploy using that module system and which includes my MIDI work. Sooner if I win the lottery... that would free up another 40 hours a week. :)
thanks,
