Version 2 Envelopes

 

Envelopes are used to provide dynamic modulation of another modules parameter(s) over time. Most typically, they are used to control the changing dynamic of a sound over time, but they are also used for may other modulation purposes, such as a dynamic changing of filter settings or pitch over time.

 

ADSR (1.2%)

The 'classic' envelope shape, with settings available for :

Attack - The time taken from the moment the envelope begins to 'open' (triggered by the gate signal) for the sound to reach its maximum level. 

Decay - Determines how long it takes for the envelope to fall back to the Sustain level, once the Attack phase is over.

Sustain - The level at which the envelope is held open whilst the gate is open. Once a Gate Off signal is received, the Release phase begins.

Release - How long it takes for the envelope to close once the gate is closed.

 

Other controls: 

The Slope setting alters the shape of the slopes which determine whether the transition between envelope points are linear or logarithmic.

Tmod1 & 2 - Modulation inputs to adjust the overall times taken by the envelope - one possible use might be to make envelope times change according to note value - the higher up the keyboard the quicker a note will both attack and decay.

Adjusts the levels of the envelope - again, this could be used with note tracking to alter the volume of notes up and down the keyboard.

ADSR B (1.4%)

As above, but lacks the Esync output, making it slightly more DSP efficient. The effect of this is that there is no guarantee that the envelope output value will return to zero before the envelope is restarted. The envelope also features an inverted envelope output, which outputs an inverted version of the main output signal.

ADSR vintage (1.4%)

Similar to the ADSR module, but with separate controls to alter the slope of the Attack and the Decay/Release slopes.

ADSR & Mod vintage (1.4%)

As above, but with additional modulation inputs for each of the Envelope stage settings and the envelope level.

AD Vintage (1.4%)

A basic envelope with only Attack and Decay segments, with adjustable slopes for both segments.

AD & Mod vintage (1.4%)

As above but with modulation inputs for the Attack and Decay segment settings and the overall level.

AHD vintage (1.4%)

Three stage envelope - Attack, Hold and Decay, with adjustable slope settings for Attack and Decay.

AHD & Mod vintage (1.4%)

As above, but with modulation inputs for all three stages and the overall level.

Multi segment envelope (1.2%)

With the multi-segment envelopes, it is possible for the user to define a very complex envelope with many seperate segments (up to a total of 128 envelope points can be defined). Each segment can be defined as a Time, Time/Note Off or Sustain segment, and any two of the segments can be set as loop points. You can define the number of times the envelope will loop round these loop points, either as a number between 1 & 256 or as Infinite. If a segment is set to Time, then the segment will last for as long as the Time specified in the 'T' box. 

The module has modulation input parameters for the envelope time and level. It also has slope parameter control to adjust the shape of the slope of the envelope.

Multi segment envelope B(0.9%)

As above, but without the ESync or slope control options.

Envelope Follower (1.6%)

The Envelope Follower outputs an envelope based on the levels of an incoming audio signal. It is possible to control both the input and output gain of the signal.  

EsyncAdd2
Envelopes need to communicate withe their triggering MVC modules for smooth and error-free Envelope operations. This is done by connecting the ESync output of the Envelope to the ESync Input of the MVC. If more than one envelope is used, you will need to use an ESync Adder to combine the Esync signals. This one allows the summing of 2 Esync signals.

The envelopes which do not have ESync output should only be used to control pitch or filters, not signal amplitude.

EsyncAdd2
As above, but allows the summing of 4 ESync signals. ESync adders can be chained if  more than 4 ESync connections are needed.
