Grp Synthesizer - Envelope Follower


The Grp Envelope Follower scans audio signals and generates a continuous control voltage based on the detected volume. Input level and threshold are adjustable. It is even possible to directly connect a microphone. The amplitude of the generated control voltage can be influenced as well. – It is even possible to invert the CV signals. As soon as the audio material fed to the module reaches the threshold, a trigger signal is generated. Thanks to the Pre Out socket, you don’t need a signal splitter to use the Grp Envelope Follower.
