Blossom traces a point around the edge of a circle as the radius of the circle varies.

The resulting two-dimensional shape generates a pair of complex, evolving, pulsing LFO signals.

Controls

• SPEED: The speed at which the point traces around the circle.

• RATIO: The number of times the radius bounces in and out on each rotation.

• FREE / LOCK: Determines whether to round the BOUNCE value to the nearest integer.

  LOCK rounds the RATIO to the nearest integer, causing Blossoms’s pattern of accents to repeat on every rotation.

  FREE allows non-integer BOUNCE values, which lets the accents vary from one rotation to the next.

• DEPTH: How far the radius bounces from the outer edge of the shape. This determines the dominance of the bounce effect in the output signals.

• PHASE: Offsets the phase of the bounce cycle.

  This has the effect of shifting where the accents occur on each rotation.

Ports

• X OUT and Y OUT: The output signals.

  The polarity switch (UNI / BI) selects the voltage range of the associated output signal. 0 to 10V (UNI) or -5 to 5V (BI).

  The GAIN knob applies gain (from 0 to 2) to the signal.

  Blossom selects the range before applying the gain.

• CV: A control voltage signal to modulate the associated parameter. Some CV signals have attenuverters.

Plotting Blossom

When plotted on a two-dimensional graph, Blossom’s X and Y signals produce a visually pleasing, flower-like shape.

To view the shape that Blossom produces, connect its X and Y outputs to a Scope’s X and Y inputs. Set the scope to X x Y mode. Note that the scope’s X/Y mode can also be interesting.
