PreSonus Notion 6 - Notation Software (Boxed) - Manual (Page 141)

9.8
In one sense, our complete library of built-in instruments makes Notion completely self-contained: no
other software or hardware is mandatory to use its features . Yet, you are not limited to these sounds: you
always have the option of assigning to any number of parts the instrument sounds from an external MIDI
device or VST instrument (VSTi) . Or, you can save time and expand sound possibilities with ReWire .
MIDI Out
A number of synthesizers, samplers, sound modules, and similar sound-generating equipment in the marketplace
play music in response to MIDI instructions . If you like, you can have Notion read a score and translate notation
and some score markings for one or more parts into MIDI signals . The external equipment then reads these signals
to produce certain instrument sounds, instead of Notion . Since the sound is generated at the external device
and not at your computer, many studio setups include an external mixer, digital audio workstation, or other
audio equipment that can “sum” together the sounds from Notion with the sounds from the MIDI device .
VST Instruments
Earlier, this guide introduced Virtual Studio Technology (VST) modules that provide sound effects, such as
reverb or equalization . This type of VST can be used with Notion, as detailed in Chapter 5: The Mixer .
A different category of VST-based software generates instrument sounds . A VST Instrument (VSTi, often marketed
as a library ) is intended to be accessed and controlled through a third-party audio application, such as Notion .
ReWire
ReWire , an industry-standard feature, enables one program (such as Notion) to control the playback
(tempo, start/stop, and much more) of another program . This widely used time-saver integrates
Notion with other audio/music applications you have on your computer so you can quickly use
the best sounds and audio features of various programs to create your musical projects .
