First Steps in Vector Synthesis
This tutorial section provides some useful hints for vector envelope programming. In
the Vector Start setting, the “mix” of the oscillators is controlled by the vector envelope.
Each oscillator has been set to a different waveform.
 Switch from the Router view to Vector view.
 In its basic (default) setting, the vector envelope has 3 envelope points. Point 1 is the
start point, Point 2 the sustain point, and Point 3 is the target in the release phase. By
clicking the points, you can see that the mix is always set to 100% for Oscillator 1, in
the Triangle.
 Click Point 2, and move the Triangle cursor to Oscillator 2. You’ll hear a square wave,
instead of Oscillator 1’s sawtooth.
 Engage the vector envelope by switching the Solo Point parameter off. As long as it
is switched on, you will only hear the selected point, with no dynamic modulation.
Having switched Solo Point off, you’ll hear the sound moving from saw to square,
with every triggered note.
 Alter the pre-set time of 498 ms, between points 1 and 2.
 While holding Shift, click between points 1 and 2. This will create a new Point 2, and
the point formerly known as Point 2 will become Point 3. The total time span
between Point 1 and Point 3 is divided into the times between Points 1 and 2, and 2
and 3. The division takes place at the click location. If you clicked at the exact
midpoint, the new time spans are equal.
 Grab the newly created Point 2, and move its cursor in the Triangle to Oscillator 2.
 Grab Point 3, and move its cursor in the Triangle to Oscillator 3. Listen to the three
oscillators morphing from sawtooth to square to a triangular wave at the final sustain
point.
 Grab Point 4 (the end point) and move its cursor in the Triangle to Oscillator 1 (if it is
not already there). Listen to how the sound returns to Oscillator 1’s sawtooth wave,
following the release of the key.
