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:

Craig, any news?

Cheers,    ...Stan
