Hmm - forgive my ignorance of the deeper aspects of OS X, but
couldn't someone write a little C proggy that waits for midi inputs,
and stores the result somewhere that his applesscript could check -
like a text file with a flag 0 if none, keypress, 1 if there is,
followed by the note #, his script would launch the program which
would run in the background, and then his script would just check
the text file periodically? Is that really impossible to do? Then he
could just hire someone to write the little app for him, and he could
continue writing his script, without having to learn the nitty gritty
of java etc?

Many thanks in advance ...
I think the answer to your very specific question is: No.
Hi there,
I'm after some advice/help and would appreciate your comments.
Basically, I'm trying to create a simple application primarily
using FaceSpan (and hence AppleScript, not AppleScript Studio) and
I need to, if possible, call a command line executable that
returns MIDI In data.
I don't need to capture any data other than the MIDI note number
of the key pressed eg, I don't need velocity, after-touch, note-
off or volume data or even the ability to route the MIDI anywhere.
So, being that I'm no C, C++, Obj C or Java programmer is there
anyway to easily create a command line executable that can be
called from AppleScript's 'do shell script' command to:-
1. run in the background waiting for a key press
2. return the decimal value of the key pressed
3. exit/quit
Hoping you can help!
Kind regards,
If you want some more general advice, I think writing something in
java using javax.sound.midi package
might be somewhat simpler and easier than programming CoreAudio in
C/C++/Obj-C.
You can also call java packages from jython ( python in java ) or
rhino/javascript, but this isn't exactly
a magic bullet. You have to understand java and the
javax.sound.midi package, as well as how the
data corecions between java and the scripting language work to use
it, so it's as best, a way of avoiding
having to write everything in java.
But, as Jeff Moore noted, it probably won't work to make a program
that runs once to grab a key press and exits.
You seem to have decided on a set of tools and part of a solution
before analyzing the problem.
That may be part of the problem.
