183MainStage User Guide
• Read root key from pop-up menu: Sets the method Sampler and Quick Sampler use to
determine the root key of audio files when loaded using Optimized mode. Choose one
of the following menu options:
• File/Analysis: Sampler and Quick Sampler first attempt to read the root key from
the header of the AIFF, WAV, or CAF file when loading the sample into a zone. If no
root key information exists in the header, then the audio samples are analyzed to
determine the root key from the longest note detected. If no pitch is detected, C3 is
automatically assigned to the zone as the root key.
• Filename/Analysis: Sampler and Quick Sampler first attempt to read the root key
from the filename when loading the sample into a zone. If the filename does not
contain that information, then the audio samples are analyzed to determined the root
key from the longest note detected. If this doesn’t provide useful results, Sampler
uses C3 as the default root key in the zone.
• Filename only: Sampler and Quick Sampler attempt to read the root key from the
filename only when loading the sample into a zone. If no root key information can be
read from the filename, C3 is automatically assigned to the zone as the root key.
• File only: Sampler and Quick Sampler read from the AIFF, WAV, or CAF file header
only in an attempt to detect the root key when loading the sample into a zone. If no
root key information can be read from the file header, C3 is automatically assigned
to the zone as the root key.
• Analysis only: Sampler and Quick Sampler analyze the audio samples in an attempt
to determine the root key from the longest note detected when loading the sample
into a zone. If no pitch is detected, C3 is automatically assigned to the zone as the
root key.
• Root Key at File Name Position pop-up menu: Determine how Sampler derives the root
key from the audio file header. Choose one of the following:
• Auto: Provides a smart analysis of numbers and keys from the filename. Sampler can
recognize a number in the filename regardless of its format—60 and 060 are both
valid. Other valid numbers range between 21 and 127. Numerical values outside of
these are generally just version numbers. A key number is also a valid possibility for
this use—C3, C 3, C_3, A-1, #C3, or C#3, for example. The possible range is C-2 up
to G8.
• Numeric value: You can set a numeric position in the filename which Sampler uses
to find the root key. This is useful when a filename uses multiple numbers, such as a
loop that uses multiple numbers to indicate both tempo and root key. For example, a
loop might be named “loop100-60.wav” to represent that it has a tempo of 100 beats
per minute and the root is the 60th position (E6). When you know the position of the
number representing the root key, you can set a numerical value to read the root key
at position eight of the filename.
• Previous Instrument pop-up menu and field: Determines which MIDI event type and
data value are used for selection of the previous instrument. Choices includeNote, Poly
Aftertouch, Control Change, Program Change, Channel Aftertouch, and Pitch Bend. In
the field next to each pop-up menu, you can enter either the note number or the value
of the first data byte. If you choose Control Change, the number field determines the
MIDI controller number.
