S906 Envelope Follower

Product Description

(This module is included in the System B)

An envelope follower receives an input audio and generates a low rate CV output that follows the level (loudness) of the input audio. This generated CV can be used later as an envelope to control other modules. The input audio is typically taken from an external source hardware/software source.

The S906 is an envelope follower with additional useful features. 4 gate outputs (comparators) are provided with 4 gate threshold (GT) knobs. These 4 outputs generate a gate whenever the envelope output goes above the set GT. 4 leds are also provided that indicate the status of the gate outputs. These gate outputs can be used later in other modules to trigger other sounds as desired.

A Speed knob is also provided which dictates how fast the envelope output follows the input. When set at minimum, the speed is 5Hz. When at maximum, the speed is 70Hz. The default speed is 50Hz. Choosing higher speeds is more accurate in the following process BUT may leak some of the audio into the envelope. Generally speaking, the lower the pitch of the audio, the lower the speed should be.
