4.1 Envelope
The Envelope module is triggered via Etch Red's Gate C V input and via
notes from Reason's MIDI input or sequencer to generate AHD
envelopes for modulating Etch Red's parameters via the TransMod
modulation system.
The Envelope can be used to modulate the Output Level so that audio
only passes through while the envelope is active, useful for triggered
envelope filtering effects. Alternatively, try modulating the filters' Freq
control, especially with the Velocity button enabled.
Velocity button
By default, the Envelope output is not dependent on incoming gate or
note velocity. With the Velocity button activated, incoming velocity
dictates the level of the envelope output.
Atk (Attack)
The Attack is the time taken for the envelope to rise from 0 to a
value of 1.
Hld (Hold)
The envelope is held at a value of 1 for the duration of the Hold time.
Dcy (Decay)
The Decay is the time taken for the envelope to return to 0.
Crv (Decay Curve)
The Curve setting controls the shape of the Decay stage. At low settings it has a linear decay
behaviour, while at high settings, the curve is exponential.
Gain [ w /Tra n sM od a m ou n t]
The Gain control offers a final attenuation control for the output of the module before it enters the
TransMod modulation system. At 100%, no attenuation is applied to the output modulation signal.
This control is intended to be modulated by other TransMod sources for dynamic, evolving
modulation effects.
Envelope connections
Gate input
The Envelope requires a standard Reason
gate signal with velocity to be connected to
the Gate input on the rear panel. It also
responds to notes from Reason's MIDI input
or sequencer.
Env output
The Env output provides the output from the
Envelope modulator so that it can be used
to modulate parameters in other Reason
devices.
