Chapter 21 ES2 293
The Vector Envelope
The Triangle and Square are the most special and unusual elements of the ES2’s
graphical user interface. Whilst the Triangle controls the mix of the three oscillators, the
X and Y axes of the Square can modulate any (modulation) target.
The vector envelope can control the movement of the cursors in the Triangle and the
Square in realtime. Each voice is equipped with its own vector envelope, which is
triggered from its startpoint with every new keystrike (or with every MIDI note-on
message, to be more precise).
The concept of the vector envelope, the Square, and the Triangle may seem strange at
first glance; but when combined with the other ES2 synthesis options, you will end up
with sounds that are truly unique—and quite literally—moving.
Envelope Points, Times, and Loops
The vector envelope consists of up to 16 points on the time axis. Each point can control
the position of both the Triangle and Square’s cursors.
The points are numbered sequentially. Point 1 is the starting point. In order to edit a
point, simply select it—by clicking on it.
