• Extended Key Range checkbox: Turn on to allow the instrument (or instruments in a
section) to play beyond its normal key range.
• When off, the instrument (or instruments in a section) plays in the original key range.
This is the default, and should be used if you are aiming for authentic-sounding
performances.
• When on, the instrument uses the full keyboard range, allowing you to create
parts that extend beyond the realistic range of the instrument (or instruments in a
section).
Studio Strings Auto Voice Split extended parameters
The following parameters apply only to section instruments when the Auto Voice Split
button is active in the main window.
• Allow Unison checkbox: Turn on to enable unison mode for split voices.
• When enabled, multiple instruments within a section can play the same note
simultaneously when a single or multiple keys are pressed.
• When disabled, one instrument within the section is played per key. To have all
instruments of a seven piece section play, you need to press seven keys.
• Split Voicing pop-up menu: Determine the octaves used by the respective voices/
instrument(s) in the section. Results vary based on your Split Mode pop-up menu
choice.
• 8va: Double the top part an octave up. This is a common technique used to make
melody lines more prominent.
• Drop 2: Transpose the second note from the top of the chord down an octave. This
technique is used to make an arrangement sound thicker and richer.
• Drop 2+4: Transpose the second and fourth note from the top of the chord down
an octave. This technique is used to thicken an arrangement. It is more suitable
for sections with five or more instrument “voices,” but can be useful with smaller
sections.
• Split Mode pop-up menu: Choose the mode used to split individual or grouped
ensemble instruments.
• Start with Lead Voice: The first incoming note is assigned to the Lead Voice, which
is usually a higher-range instrument such as a violin. All subsequent notes are
assigned, in descending order, to the Middle and Bass Voices.
• Start with Bass Voice: The first incoming note is assigned to the Bass Voice. All
subsequent notes are assigned, in ascending order, to the Middle and Lead Voices.
• Start by Key Split: Incoming notes below the defined split key (set with the Split Key
pop-up menu) are assigned to the Bass Voice and the lower Middle Voices. Notes
above the split key are assigned to the Lead Voice and the higher Middle Voices.
• Split Key pop-up menu: Set the MIDI note number used as the split point for individual
ensemble instruments.
Note: This parameter applies only when Start By Key Split is chosen in the Split Mode
pop-up menu.
