Chapter 22 ES2 273
Vector Int—The Modulation Intensity
The maximum intensity, sensitivity, and polarity of the modulation is set with the Vector
X Int and Vector Y Int parameters.
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 real-time. 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 believe us: Combined with the other synthesis possibilities of the ES2,
and you will end up with sounds that are truly unique and literally, moving.
Envelope Points, Times, and Loops
The Vector Envelope consists of up to 15 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.
Sustain Point
Any point can be declared the Sustain Point. Given that the note played is sustained
long enough and there’s no loop engaged, any envelope movement will stop when
this Sustain Point is reached. It will be sustained until the key is released (until the MIDI
note-off command).
