Install and use Scala on Mac OS X 10.4
You need OS X version 10.3 Panther or higher with the X11 package installed.
Download the latest Scala version for OS X on PowerPC/Mac from
Please follow this carefully:
- Check if X11 is installed. If so, you should see an X11 icon inside
Applications/Utilities/X11. If not, download the latest X11 package from the Apple website:
- Drag the whole folder inside Scala-dist which is called "Scala" into the Applications folder.
The naming is confusing unfortunately. You may want to use another view type than the
- Double click on the application icon Applications/ScalaX (ScalaX, not Scala)
- Type "help" in the bottom of the "scala" window
Be aware that Scala doesn't produce any sound by itself. It needs a MIDI
connection to an instrument, whether external or internal via the IAC bus or a
virtual port provided by an installed software synthesizer.
There is a decent freeware program called SimpleSynth.
It plays via Apple's DLS Synthesizer and it can set soundfonts:
To make a virtual IAC port, close Scala first if it's running.
Then in Audio MIDI Setup utility, double-click on IAC driver if it's greyed out.
Check the box "driver is online". In the "ports" dialog you can create
Then start Scala, and go to Edit:Sound Settings or press Ctrl-G and select the
same port for the MIDI Output Device. Click OK or Apply.
Then open the Chromatic Clavier for example or press F4 and try if you get
These programs might also be helpful: MidiPipe
and MIDI Patchbay.
For sending keyboard tunings to an external synthesizer or other instrument, a
MIDI file player is required. The Scala installer includes one,
and you find it in the Scala install directory. It should not be removed from there.
Install the scale archive
Don't download it into the Desktop folder where Stuffit would unzip it automatically.
Safari browser users, control-click on the link and choose "Save Linked File
As...", then save to any folder other than Desktop (i.e. the Scala folder
would be a good choice). Then open Terminal, navigate to that folder
with the cd command, and type:
unzip -a scales.zip
Warning: you must unzip them with the -a (autoconvert) option, otherwise they cannot be opened!
Lines will terminate with <CR><LF> instead of <LF>, so to
use Stuffit is a bad idea.
The files will go to a subdirectory "scl" of the current directory (again the Scala
folder is the best choice).
