The Solo instruments use more memory than the Player instruments.
Garritan instruments like Piccolo Solo, Flute Solo, Oboe Solo, etc., are designed to be used when your score has only one instrument of that type - for instance, in a piece for wind quintet, you would normally use Flute Solo, Oboe Solo, Bb Clarinet Solo, Bassoon Solo, and French Horn Solo. These Player variations all have slight differences in timbre and intonation and are designed to be used together in a flute section - this way, unison lines played by two or three flutes sound like authentic unisons, instead of sounding like a single flute. Garritan instruments like Flute Player 1, Flute Player 2, and Flute Player 3 are best used when your score/ensemble has multiple players of that instrument type - for instance, if your score calls for three flutes, you would probably want to assign the Flute 1 staff (or layer) to Flute Player 1, the Flute 2 staff/layer to Flute Player 2, and the Flute 3 staff/layer to Flute Player 3. This section will discuss the differences between these variations and how best to use each one. These contain options such as “Player 1,” “Player 2” and 'Solo'.
As you look through the instruments that are available to you with Garritan Instruments for Finale, you will notice many variations on individual instruments.
