2. PatchBay Settings
If you're using the MIDI Manager, open PatchBay and check the VVE and Macintosh serial
output connections. These settings are normally saved and will be automatically recalled the
next time you start the VL Visual Editor. The PatchBay parameters may have to be reset if one
of your MIDI applications is aborted abnormally or any other MIDI setting is changed.
VL1-m Users:
For VL1-m users, Yamaha recommends using an external MIDI merger unit to merge the MIDI
output from the Macintosh computer and the controlling keyboard (or other controller) to be
sent to the VL1-m MIDI input. If no hardware MIDI merger is available, use the Apple PatchBay
application to route both the keyboard MIDI output and VL Visual Editor MIDI output to the
VL1-m MIDI input. The latter "software merge" setup should work on most systems, but is
likely to be less reliable than the recommended "hardware merge" approach.
3. MIDI Settings
Pull down the "Window" menu from the menu bar and select the "MIDI …" item. In the pop-up
window enter the MIDI channel and device number used by your VL instrument. 
4. Synthesis
Click on any of the "DRIVER" options to the left of the window to select it (the selected
driver will be outlined in red). Next click on one of the PIPE/STRINGS options to the right of
the window — the selected PIPE/STRINGS option will be outlined in red. A composite image
representing the selected DRIVER and PIPE/STRINGS options will appear in the "PREVIEW"
window.
