S-610 Composer N (notes) module for Eurorack / Doepfer A100 system.
From the top down:
CLK: Clock input jack (trigger) + LED
ENBL: Enable input jack (gate) + LED
PROB: Probability of new note being generated knob + new note generated indicator LED
SPRD: Note Spread knob
S LEN: Sequence Length knob + LED
QUANT: Quantizer knob + LED
ALG: Algorithm selection button + LED
CV: Control Voltage output jack (1v/octave)
The S-610 Composer N is a sequencer with up to 32 steps that generates semi-random patterns of notes. A new trigger or gate at the Clock input jack cycles between those notes. A steady clock or LFO signal will generate a steady stream of notes; use the Gate Out of the S-620 Composer G or other trigger pattern generator to create more interesting patterns with rests.
You can control the probability of when new notes are randomly generated, and what their values might be. The Enable input decides when there is a probability of this happening. It defaults to On (enabled), which can be overridden with an external gate signal; its status is confirmed by an LED. If the Enable input is On for the next note in the sequence, the S-610 then looks at the value of the Probability knob to determine whether or not a new note value will actually be generated.
There are three different note selection algorithms to choose from, indicated by the Algorithm LED at the bottom of the module: Off = algorithm 1, dim = 2, and bright = 3. Briefly press the Algorithm button to cycle through the algorithms.
If you always want new notes to be randomly generated when the Enable input is On, then set Probability to full clockwise. To have the S-610 operate like a sample & hold and generate a constant stream of random notes, leave Enable unpatched, and turn Probability full clockwise. To keep the current sequence of notes, either send 0 volts to Enable, or turn Probability full counter-clockwise.
If its Probability LED is on, then a new note is being generated. If this new note has a different value than the current note, the LED will be at full brightness; if the LED is dimmed, the new note generated had the same value as the current note. If the LED is off during a note, Probability decided not to generate a new note this time around.
This gives you very fine control over which notes are replaced in a sequence, and when. For example, if the sequence Length (S LEN) is set to 4, and you send Enable a new gate signal only on the first note of a 4-note bar, only the first note has a probability of being changed, while the other 3 notes will be kept the same. If you patch a drum pattern gate output to Enable, new notes can be chosen only when a drum hit also occurs on that beat. You can also patch a Ladik U-070 or U-075 module to Enable and use their manual gate buttons to decide when you want new notes to potentially be generated.
The Spread knob sets the range for the new note to be generated. Turning it counter clockwise will result in new notes with similar values; turning it clockwise will increase the potential size of the interval between new notes.
The Sequence Length knob is used to set the length of the repeating sequence: 1, 2, 3, 4, 6, 8, 12, 16, 24 or 32 steps. Its LED turns on if you have selected a length that is a “power of 2” (2, 4, 8, 16, or 32) steps long.
The Quantization knob chooses between 16 different scales. The LED alternates between on and off to confirm you’ve selected a different scale.
To choose an alternate set of scales with limited note values (just three or four notes – good for bass lines), hold the Algorithm button until the LEDs for Algorithm and Quantization blink rapidly, then release; after a second, the Quantization LED will change to a dimmed value when on to indicate you are choosing one of these minimal-note scales. Press and hold Algorithm button again to revert back to the normal scales.
Width: 4TE/ 4HP/ 20mm
Depth: 42mm /1,7″ max.
Power cable included
Double check power connection before powering your system please.
„Red strip“ means -12V connector side in Eurorack standards.
In some power distribution systems connector key can be reverted.
In this case cut connector key and plug power connector right way (with respect to red strip) or use different power cable appropriate to your power system.
