[CM] CM 3 / Linux cant see midi ports.

[taube at illinois.edu]

I think you have to do this:

1 start grace
2 start qjackctl
3 click on the Connect button in the main window
4 click on the Alsa tab in the connections window
5 Click on "Juce Midi Output" in the Output Ports pane
6 click on whatever you want in the Input Ports pane (I use Timidity, which sound pretty good)
7 Click on the Connect button
8 Select the Grace application again
9 select the same output device in the MidiOut menu
10 use Test Midi to test the sound

what could be simpler!!

ps im glad to see that someone else can build from sources ;)   the current svn makes this process even easier -- cm has the juce sources built in so you no longer need to instal/configurel/build a juce lib. the new method works great on linux mac and windows.   to use these "amalgamated" juce  sources instead of an external juce installation omit any --juce option from premake and it'll use the preconfigured juce sources cm has in its source tree

premake --verbose --target gnu --sndlib /path/to/sndlib
make

and away you go. its pretty cool.
