DR. REX LOOP PLAYER
142
Setting Number of Voices - Polyphony
This determines the polyphony, i.e. the number of voices, or slices, Dr.Rex
can play simultaneously. For normal loop playback, it is worth noting that
slices sometimes “overlap”. Therefore, it is recommended that you use a po-
lyphony setting of about 3-4 voices when playing REX files. If you are “play-
ing” slices via MIDI, the polyphony setting should be set according to how
many overlapping slices you want to have.
! Note that the Polyphony setting does not “hog” voices. For exam-
ple, if you are playing a file that has a polyphony setting of ten
voices, but the file only uses four voices, this won’t mean that you
are “wasting” six voices. In other words, the polyphony setting is
not something you need to consider if you want to conserve CPU
power - it is only the number of voices actually used that counts.
Audio Quality Settings
These two parameters provide ways of balancing audio quality vs. conserva-
tion of computer power.
High Quality Interpolation
When this is activated, the loop file playback is calculated using a more ad-
vanced interpolation algorithm. This results in better audio quality, especially
for loops with a lot of high frequency content.
➜ High Quality Interpolation uses more computer power - if you don’t
need it, it’s a good idea to turn it off!
Listen to the loop in a context and determine whether you think this set-
ting makes any difference.
! If you are using a Macintosh with a G4 (Altivec) processor, turning
High Quality Interpolation off makes no difference.
Low Bandwidth (BW)
This will remove some high frequency content from the sound, but often this
is not noticeable (this is especially true if you have “filtered down” your loop).
Activating this mode will save you some extra computer power, if needed.
