2.Overview
The envelope panel adjusts the amplitude of its input. Output = Input * gain. The envelope is defined as a piece-wise linear approximation by defining the coordinates of the points. The envelope definition is provided as a two-dimensional array, called a “xy-map” with n points. It is assumed that for all points, the x values are rising. For each x value there is a corresponding y-value representing the amplitude gain (both x and y are 0…±1 normalized). There are two envelope play modes, loop and one-shot mode. The total time of envelope depends on duration time and repetition time.
3.Build time parameters
| Configuration parameter | Values |
| # of Channels | 1 – 64 |
| Object Mode | “Loop” or “One Shot” |
| Table Number | 1 – 64 |
| Table Height (1-64) | 2 – 512 |
4.Envelope Panel
The Envelope panel contains LUT panel’s table and chart.
Userguide for LUT panel can be found here: LUT Userguide
The Envelope number of tabs depends on “Table Number” value in SFD configuration.
Point number of Envelope table depends on value of “Table Height”
The envelope table is provided as two-dimensional array, called an “xy-map” with n points.
For each x values there is a corresponding Y value representing the linear gain value.
All X,Y shall be configurable by GTT as a 32 bit float, 0…1 normalized.
