DR. OCTO REX LOOP PLAYER
(RECORD+REASON)

Setting number of voices - polyphony
This determines the polyphony, i.e. the number of voices, or slices, Dr. Octo Rex can play simultaneously. For normal
loop playback, it is worth noting that slices sometimes “overlap”. Therefore, it is recommended that you use a polyph-
ony setting of about 3-4 voices when playing REX files. If you are “playing” 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 example, if you are playing a file that has a polyph-
ony setting of ten voices, but the file only uses four voices, this doesn’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
Dr. Octo Rex features two parameters that provide ways of balancing audio quality vs. conservation of computer
power. The parameters are called “High Quality Interpolation” and “Low Bandwidth” and are located to the right on
the rear panel:
High Quality Interpolation
When High Quality Interpolation is active, the loop file playback is calculated using a more advanced interpolation al-
gorithm. 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 setting makes any difference.
Low Bandwidth
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.
