• The "Loop" and "Loop Reverse" pitch algorithms:
By turning the Delay knob you can move the loop position within the Delay Buffer. You set the loop length with the
"Length" knob and define the loop type with the
With longer loops there might not be any audible changes of the sound when you start to reach the end posi-
!
tions of the Buffer. This is because the loop start/end will reach the Buffer's start/end position before the De-
lay knob does.
Sum L+R
Click this button to make Polar perform the pitch analysis and resynthesis on the sum of the Left and Right input
signals. This saves processing power since only one (merged) input signal is analyzed and processed. The other
processing channel is automatically switched off. You can still pan the processed sound on the Polar outputs as
desired to create a stereo output effect.
The Sum L+R mode is suitable in two scenarios:
• If only the Left Audio Input of Polar is connected because you are processing a mono sound.
• If you are processing a stereo sound that has similar character on the left and right channels.
For example, this could be a stereo synth pad, a stereo piano or basically any "single instrument" sound.
The Sum L+R mode is not suitable if the stereo sound you are processing has different character on the left
!
and right channels. Also, if you want to preserve the original panning of the input stereo sound you are pro-
cessing, make sure the Sum L+R button is Off.
