S713 Swing/Rotate Clock Divider/Multiplier

Product Description

 

(This module is included in the System B)

 

The S713 is a quad clock divider and multiplier with swing and rotation capabilities. This design helps in quickly creating evolving rhythmic triggers from only one input clock.

 

Each of the four sections can work as either a clock divider or multiplier, chosen by a Div/Mult switch. The numbers on the knobs to the left indicate the divide-by value or the multiply-by value. Each section has different values than other sections. Values range from 1 up to 28. Hint: try setting all knobs to the same position.

 

Each section has a swing knob that will swing every other trigger output*. A blue led indicates the output trigger/gate status.

 

Each one of the four sections is routed to one of four outputs depending on the current Rotate knob/CV setting. As it increases or decreases. The sections outputs are moved and rotated across the four output ports. Each section has 4 red LEDs. Only 1 of those LEDs are lit at any given time indicating which one of the four outputs the section is currently routed to.

 

A Rst In (Reset In) port is provided. When a high CV (>=0.25V) is detected here, all four sections will be reset and will remain so as long as the voltage at Rst In remains high. Normal operation proceeds if low CV (<=0.15V) is detected. If mid level CV is detected (i.e between 0.15 and 0.25), then the module will pause its clocking operation but WITHOUT reseting, this means that the 4 sections will hold their current states.

 

The S713 can handle audio rate input equally well !!. As weird as this may sound, it can be used as a LoFi octave/pitch shifter. The swing features would sound like pulse width modulation in this case.

 

Further Details

Dividers are fundamentally more accurate than multipliers. This is because when the input clock speed changes, a multiplier will always have to wait for the next clock to know the correct speed, during which it will assume the previous speed and generate triggers at the previous speed. This problem is not present in dividers because they are always slower than the input clock and can always wait until the next clock comes without resulting in off-sync situations. However, a multiplier has the advantage of being able to generate endless triggers/gates without requiring a constant input clock. This is useful for example for generating a tap-tempo by connecting the S709 manual trigger to the Clk In and taping in the desired tempo (set the first section to Mult and the knob value to 1 in this case).

 

By default a multiplier will never swing a trigger when the input clock comes or when it’s expected to come. To turn off this behavior, set the Mult Unswing switch to off. This will take the swing status of the last trigger and apply it to the trigger at the input clock***.

 

 

*Except at the input clock time for the multiplier case.

**High CV is 0.25V and above.

*** it will not flip the swing status because the clock might be a bit late or early which can create undesired problems when the clock speed changes.
