Getting connected and installing drivers (Macintosh)
Does the OUTPUT level indicator of the SD-20 move?
If the OUTPUT level meter in the SD-20's display is moving but you do not
hear sound, check whether the volume of the SD-20 or your speaker system
has been lowered. If the OUTPUT level meter does not move, check the
connections and OMS settings once again.
After you have made settings correctly, choose Test once again from the
Studio menu, and perform step 9.

Exit OMS Setup.
From the File menu, choose [Exit]. If the AppleTalk confirmation dialog box
appears, click [OK] to close the dialog box.
This completes connections for the SD-20 and Macintosh, and installation of
the MIDI driver. Now, MIDI data can be input and output (recorded and
played).
