LFO Sequencer V4
This is a refined and expanded version of the LFO sequencer which uses an LFO and sample and hold to make melodic sequences. This version incorporates a built-in pitch quantizer, clock divider, and Euclidean pattern generator to facilitate this task.
I/O
| Input | Signal Range | Notes |
|---|---|---|
Bias |
-4 to 4 |
This input is calibrated to 1/oct signals to transpose your sequence or introduce a second sequence signal. |
CLK |
0-1 |
Clock input to trigger the sample and hold and increment the internal counter. |
reset |
0-1 |
This resets the internal counter and resets the LFO to the beginning of its cycle. |
| Output | Signal Range | Notes |
|---|---|---|
LFO |
0-1 |
This output is a scaled version of the internal LFO shape that is creating the melody for creative modulation. |
1/oct |
-4 to 4 |
Pitch output for the sequencer. |
gate |
0-1 |
Provides rhythmic output for the sequencer. |
Controls
| Knob/Switch | Function | Notes |
|---|---|---|
lngth |
Determines length of sequence and Euclidean pattern. | The display to the right of it shows the current step above the max length. |
div |
This is a counter-based clock divider that divides the pace of the sequence. | The display to the right of of it shows what the steps are currently divided by as well as when the next step is relative to the incoming clock signal. |
rate |
Controls both rate and shape of the internal LFO. | The shape is a complex combination of two sign waves. |
polarity |
This controls the amplitude as well as the polarity of the LFO. | This is a bipolar knob, with a value of .5 effectively muting the LFO. |
bias |
This transposes the sequence and offsets the LFO output. | This is a bipolar knob, with a value of .5 centering LFO. |
phase |
Controls where in the LFO’s cycle the sequence begins. | Great for creating musical rounds. |
scale |
Selects the type of scale the quantizer is set to. | The display to the right of it will give you an indication of which scale is currently active. |
root |
Selects the root note of the selected scale. | The display to the right of it gives you an indication of which root note is active. |
hits |
This controls the density of the Euclidean pattern. | The display below it shows how many steps will have hits that trigger the gate output. |
offst |
This controls the offset or rotation of the Euclidean pattern. | Great for creating variations of the same melody across different synth voices. |
loop |
Allows the Euclidean pattern to loop at a different rate than the LFO pattern. | Great for creating longer, more complex sequences. |
hold |
When active the 1/oct will only change when there is a hit in the Euclidean pattern. |
Very useful when creating a sequence with longer releases on the envelope. |
Also included is a CV utilitie for the Expert Sleepers ES-8 module that allows you to sequence your eurorack gear with this module, including an onboard octave switch and envelope generator.
