Value Sequence Module

The Value Sequence Module implements a 16-stage triggered sequencer with adjustable direction and wrap-around positions. This module is useful for complex internal control within a patch, and is often well paired with the Sample Hold Module to create musically interesting extended sequences. See this cool tutorial by Doug Lynner to see a similar example on the Serge Analog Synthesizer.

To set sequence values in this interface, simply click on one of the small slider thumbnails in the slider array and drag up or down. To make fine tuned adjustments, hold down the shift key while dragging.

For a key to understanding the following tables, see the Module Types page.

Adding Input Ports

Adding input ports is not enabled for this module.

Static Parameters

#	Title	Type	Description
0	Stage Values	Sequence Value Array	The sliders in this parameter user interface adjust output values at each stage in a sequential sequence (it's really 16 parameters in one). Parameter values have the range [0, 1].

Input Ports

#	Title	Description	Input Scalar Used	Parameter Scalar Used
0	Step Trigger	When the parameter-scaled value of this input signal rises above 0.5, a transition to the next sequence stage will occur, where the next stage is determined by inputs to Ports 3 & 4.	NO	YES
1	Quantization Factor	For non-zero input signal to this port, the Value Sequence will lock to proportionately quantized output values.	NO	YES
2	Smoothing Factor	Input this port will determine the degree of intermediate smoothing which occurs between subsequent values as the sequencer moves between stages, allowing the output to move from sharp transitions (for input zero), to extremely smooth and rounded ones.	NO	YES
3	Start Stage Offset	This input signal indicates the address, in the form of a ratio in range [0,1], of the first stage in sequence playback, in other words the stage the sequence will loop back to when it it leaves the end stage. This value may be larger than the End Stage Offset signal routed to Port 4, in which event the sequence runs backwards between the two addresses.	NO	YES
4	End Stage Offset	This input signal indicates the address, in the form a ratio in range [0,1], of the last stage in sequence playback. When the sequence leaves this stage, it next steps to the address specified by the Start Stage Offset signal. This value may be less than the Start Stage Offset, in which event the sequence runs backwards between the two addresses.	NO	YES

Output Ports

#	Title	Description
0	Output Value	The current active stage value in the sequence, or a smooth transition if the stage is changing.
1	Stage Counter	A value in the range [0,1] which indicates the address of the currently active stage in the value sequence.
