This module provides a pair of 16 step sequencers designed for general purpose control voltage sequencing. For more specialized sequencing tasks check out the Adroit Rhythm Sequencer, Melody Sequencer and Progression modules.

The module’s two sequencers work in sync so the same step is always active in both but they are otherwise independent.

Each sequencer has an area that shows colored bars representing the sequenced voltages. Use the mouse to alter the sequence. You can hold down the left mouse button and quickly “draw” shapes or you can click on individual bars to change just one step.

As with all Adroit Synthesis sequencers the timing it is controlled via the voltage input to the V/Bar In socket. See V/Bar for more detail.

Each sequencer has a bank of buttons that perform useful tasks, note the RECORD buttons – yes these sequencers can do real-time recording as well as regular step sequencing.

The lower sequencer also controls the gain of a handy built-in voltage controlled amplifier (VCA).

You are not limited to just 16 steps as sequence lengths can be extended indefinitely using the Song Control Sequencer, Time Splitters and the MERGE sockets to chain any number of CV Sequencers together.

Each sequencer has its own set of the following inputs, outputs and controls.

The CV OUT socket transmits the current control voltage value in the sequence. By default the range is 0 to 5 V but this can be adjusted by the RANGE and OFFSET knobs.

The RANGE knob scales the voltage range of CV OUT anywhere between 0 and 10 V. Its default setting (at 12 O’Clock) is the standard 5 V.

The OFFSET knob adds or subtracts a DC voltage to the output of between -5 V and +5 V. It’s default setting (at 12 O’Clock) is zero.

So at their default settings the RANGE and OFFSET knobs configure the output to range between 0 and 5 V. But if RANGE is set to maximum and OFFSET to minimum then the output will range from -5 V to +5 V.

Precise values can be set by using either knob’s Edit Value menu option.

The REC IN socket accepts a 0 to 5 V signal to be recorded. See the section on recording for more detail.

The MERGE IN socket allows multiple CV Sequencers to be easily chained together with each module passing its CV OUT signal along to the next module in the chain. See the section on chaining for more detail.

The colored bars act as both indicators as well as input mechanisms for each step’s setting as described earlier. The currently activated step is highlighted. When the GLIDE button is engaged a white line is drawn indicating the slope of the voltage over time.

RECORD arms the sequencer for recording. See the section on recording for further details.

RESET sets all steps to their midpoint default value.

REVERSE reverses the order in time of the steps.

SINE sets the steps to represent one full cycle of a sine wave. The shift buttons can be used to alter the phase of this wave.

< SHIFT shifts the pattern one step to the left (earlier in time), rotating the first step to the last.

SHIFT > shifts the pattern one step to the right (later in time), rotating the last step to the first.

GLIDE when engaged makes the output voltage glide smoothly from one step to another using linear interpolation. A white line show the slope. See the section on glide for some technical details about exactly what happens at boundaries.

RANDOM sets the steps to random values.

NORMAL performs a normalization on the values. In other words it stretches and shifts the values so that the pattern occupies the full vertical range.

SMOOTH performs an averaging operation on the values that acts like a low-pass filter ironing out sharp edges. It can be applied once or multiple times to achieve the desired amount of smoothing.

RISE sets the values in increasing order to create a ramp. Use REVERSE to transform a rise into a fall.

The COPY and PASTE buttons allow you to copy data from one CV Sequencer to another, either within the same module or between them – handy for quickly creating subtle variations like phase shifts. Click on COPY to copy the pattern to the clipboard. Click on PASTE to copy a pattern from the clipboard.

COLOR enables you to select a color for the sequencer bars. This is great for color coding different functions especially in a large patch. For instance you might choose to use green to represent filter cutoff. Or you can just pick colors to brighten things up (Adroit modules are purposely rather neutral looking so as to not grate on the eye during prolonged sessions).
