WHAT'S THAT THING ?
The CANON, is, as its name suggests, a module to create a canon effect (!) between 2 voices.

Wikipédia: Canon_(music)
A theme that is repeated and imitated and built upon by other instruments with a time delay, creating a layered effect.

In the modular world, it's Simply a delay for CV and GATE.
But unlike an audio delay (that records audio at 'audio rate') the CANON records data only according to a clock signal.
With the CANON module, you can delay until 16 steps.

The CANON can delay one GATE and one CV
(+1 CV with an extension).
Of course with CV controle of the number of steps. With the unique knob: Nb Steps.

To be more playable, there are two more functions:
Reset (RST), to clear the memory, that can be useful to not let the sequence running if you don't want that.
Enable (EN). In this case, the input is ignored. The module will works like a small sequence memory of 16 steps.
The Nb Steps knobs will controle the duration of the loop.

To resume, The module needs a Clock signal (CLK)
A CV and a GATE input.
And you will have the same things as the input, shifted !
Then a Reset button + Jack to clear the memory. (RST)
And a Enable button + Jack to freeze the memory. (EN)

With an external module, like the Mult., you can delay one more CV.

Typical use:
Building musical canon.
Save and play with the sequence in the memory.
creative re-construction of sequence.
