The Square
The Square has two axes: The X and Y axes have positive and negative value ranges.
They are bipolar, in other words. By touching and moving the cursor with the mouse,
the values of both axes are continuously transmitted. As you can modulate one freely
selectable parameter with the X value, and another freely selectable parameter with
the Y value, you can use the mouse like a Joystick.
As an alternative to this real-time control, the position of the cursor can be modulated
by the Vector Envelope—just like the mix between the three Oscillators in the Triangle.
The Loop function of the Vector Envelope generator allows for cyclic movements. This
opens a number of doors, allowing it to operate as a two-dimensional, luxurious
pseudo-LFO with a programmable waveform. More on this is found in The Vector
Envelope” section, on page 273.
Vector Mode
Vector Mode allows you to disable the control of the Square cursor by the vector
envelope. The same parameter also defines whether or not the Triangle (the oscillator
mixer) shall be controlled by the vector envelope.
Vector Mode Off—The vector envelope does not influence the Triangle or the Square.
Its simply switched off. This allows you to set and control the cursors of the Triangle
and the Square in real-time.
Vector Mode Mix—The vector envelope controls the Triangle (the oscillator mix), but
not the Square.
Vector Mode XY—The vector envelope controls the Square, but not the Triangle.
Vector Mode Mix+XY—The vector envelope controls both the Square and Triangle.
Note: Like all of the ES2’s parameters, the movements of the cursors in the Triangle and
Square can be recorded and automated by Logic. This automation data can be edited
and looped in Logic. This is completely independent of the cyclic modulations of the
Vector Envelope. Vector modulation of the Square and Triangle should be disabled for
this type of use (Vector Mode = off).
Vector Target—Modulation Destinations
The Vector X and Vector Y target parameters determine the effect of cursor movements
in the Square. The modulation targets are identical to those available in the Router, so
we won’t repeat ourselves here. Please see the “Modulation Targets section, on page
254 for descriptions. The position of the cursor in the Square is also available in the
Router, as the Pad-X and Pad-Y Source and Via options.
