Analog Heat +FX contains an envelope follower function. The envelope follower is used to detect the

amplitude variations of the incoming audio signal to produce a control signal (envelope) that resembles

those variations. The control voltage rises and falls with the overall volume of the input signal. This con-

trol signal is routed to modulate the filter and also to two other modulation destinations of your choice.

For more information, please see "7.4.9 MATRIX" on page 36. Tightly coupled with the Envelope

Follower is also an Envelope Generator. If you do not want to use the follower output directly, you can

choose to use the follower only to trigger the Envelope Generator, if you want to use predefined Attack/

Decay (or Attack/Release) times rather than follow the audio with the rise/fall slopes. For more informa-

tion, please see "4.2 MODULATION SIGNAL FLOW" on page 12.

MODE Sets the mode of the envelope follower. Turn the knob to access the next mode. The higher

the value under the selected mode, the more gain is added to the signal, which is useful for weak input

signals.

• AR (Attack-Release)

Creates an envelope control signal where the Attack phase begins when the incoming sound ex-

ceeds the threshold. The envelope then holds until the incoming sound falls under the threshold

and the release phase starts

• AD (Attack-Decay)

Creates an envelope control signal where the Attack phase begins when the incoming sound

exceeds the threshold and is then followed directly by the decay phase.
