> Thanks a lot for your help.  I've run into problems satisfying the dependencies and decided to stick with version 3.8.  I had hoped that by upgrading from 3.8 I could solve my audio problem (the MIDI works, but not the ALSA audio output), but there is probably an easier way of doing that.

What are the audio problems? Grace doesn't call alsa directly and its app-specfic audio code is really quite small -- basically a little audio file player --  and its working on my system (see below), which is the lasted stable Ubuntu running on virtual box.  Actual audio file writing is handled by sndlib and its also working fine on my linux

For audio/midi playback problems on linux i think the first place to start is the Juce Demo App -- If the Demo App's audio page works then the equivalent should work in Grace (because its not doing anything different). If it doesn't work then you have a fail case that people on the Juce forum could most easily help you with.

The one audio issue I have on my linux is that  its running in virtual box, and for whatever reason its audio input devices are failing somewhere deep in libasound  -- this results in a very long timeout in some alsa thread. If this is the problem you are having then you can edit Audio.cpp and set the max number of input devices to 0:
change:
  audioDeviceManager.initialise(2, 2, 0, true);
to:
  audioDeviceManager.initialise(0, 2, 0, true);

I could do that for all linux but that seems rather draconian. You will find that same issue in the Juce Demo, its nothing to do with Grace.

On a slightly different topic, can someone tell me what steps i need to take to generate a sound in midi on Linux?  Im not sure anymore how to do this, what app do i use and how do i make connections??

This is covered in the section "Building a static JUCE library on Linux" at the end of the read me and includes a link to an explanation of what exactly you will need to install and how to install it.

After installing premake and trying "premake premake4" (and later, "premake --premake4," "premake --premake4.lua", etc.) I get the response "No premake script found!"  But isn't premake4.lua the script in question?  And how to I invoke it?  (I've already tried making it executable, and even the cm directory to PATH.)

If you deselect all midi out devices in the menu, Grace will switch to its new internal synth plugin ("apple's dsl music synth") when you generate midi.  the plugin sounds much better than SimpleSynth. you can tweak plugin parameters using the new "Synth Settings..." item in the audio menu
