SWEEPER MODULATION EFFECT1119
Audio Trig
It’s also possible to trigger the envelope from the audio running through Sweeper.
D Activate the Audio Trig function and set the Threshold value as desired.
When the audio level in Sweeper exceeds the set Threshold value, or quickly increases when above the Threshold
level, the envelope is triggered.
• If the envelope is not in Loop mode, one complete cycle is completed at the most. The cycle continues to play
back as long as there is audio present through the Sweeper device.
• If the envelope is in Loop mode, the loop plays back from the very beginning when an Audio Trig signal is re-
ceived. The loop continues to play back as long as there is audio present through the Sweeper device.
The Audio Follower Modulator
The other part of the Modulator section is the Audio Follower. This is basically an envelope follower, which tracks the
level of the audio running through Sweeper and outputs a control signal that can be used for modulating the Fre-
quency parameter of the Phaser/Flanger/Filter section, for modulating the Volume, and for modulating the LFO
Rate. The tracked (followed) audio level is shown in real-time in the display.
Gain In
Here you can attenuate or gain the modulation signal level, to adjust it to the audio signal level.
Attack
This controls how fast the envelope follower should react after the input signal level has increased from one value to
a higher.
Release
This controls how fast the envelope follower should react after the input signal level has decreased from one value to
a lower.
