 Brian, Michael,
 Scala only depends on GTK+ and GtkAda. I'm not sure about the status
 of GTK+ on OS X, but there is Gimp so I suppose it's available.
 Porting to the native OS X gui instead will be a lot of work though.
 GNAT is available, versions 3.12 to 3.15 will all be fine.
 The OS calls are done via the portable GNAT libraries so all that
 will probably work straightaway.
 So Brian I'd say try installing GTK+ 1.2, GNAT and GtkAda 1.2.12 and
 I'll send you the code. See

 I don't know anything about MIDI on OS X, but it can do without.
 We should continue offlist now.
