This item is always in the inputs list, even if no keyboard device is defined. However, for any
MIDI input to be received on an Instrument Track, your MIDI input device (Keyboard
Controller, etc.) must first be set up in the External Devices menu as a Keyboard.
5.2.3 Set Up a Virtual Instrument
Studio One Producer and Professional support VST and AU virtual instruments, ReWire
applications, and Studio One's Native virtual instruments. The difference between these types
of virtual instruments is transparent to the user in Studio One, as they are all handled in the
same manner. To use any VST or AU virtual instrument, you will need to be sure Studio One
knows where they are installed on your computer. Refer to the
"Setup" chapter for more information on locating your plug-ins.
5.2.4 Add a Virtual Instrument from the Browser
To add any VST, AU, ReWire, or built-in virtual instrument to your Song, open the Browse view
and click on the Instruments tab to view your virtual instrument. Then do one of the following:
• Click on and drag any virtual instrument to an empty space in the Arrange view to
simultaneously add the virtual instrument to your Song and create an Instrument
Track with its output routed to the virtual instrument. The Instrument Track will
conveniently inherit the name of the virtual instrument.
• Click on and drag any virtual instrument on top of an existing Instrument Track to
replace the track's current virtual instrument.
• Click on and drag any virtual instrument to the Instruments window in the Mixer to
simply add the virtual instrument to your Song. In order to control or play this virtual
instrument, you will need to select it as the output for an Instrument Track.
• The virtual instrument is now set up and ready to play and will have one or more
dedicated audio channels in the Mixer.
Once a virtual instrument is added to your Song, be sure that an Instrument Track is routed to
it so that the instrument can be played.
5.2.5 Set Up Multiple Virtual Instrument Outputs
Many virtual instruments have the capability to send audio on more than one channel. In
Studio One, only the first output or output pair of any virtual instrument will be active by
default.
