9.6.2. About Changing Shapes
As we've mentioned before; a unique feature of this envelope is that it is possible to
modulate the shape of the Rise and Fall stages. To make changes to these stages hold the
Shift button and turn the Rise or Fall button. Turning it to the left will make the shape more
logarithmic, turning the encoder to the right will make the shape more exponential. There's
a dead zone in the middle where the shape is linear. The info screen will display "LINEAR"
when you're in that zone.
Note:
In case you're not familiar with the terms
logarithmic, linear, and exponential, they
are terms that describe the curve of a line. A curve is said to be exponential when it is slow
to rise and picks up speed when nearing its endpoint. A logarithmic curve is the opposite of
this, eager to rise and slow to finish. A linear line is a straight line from beginning to end.
When applied to an envelope these slopes will give the envelope a particular character: an
exponential rise and a logarithmic fall will create the impression of a somewhat sluggish
envelope. If you reverse these stages and combine a logarithmic rise with an exponential
fall, the envelope will seem to start more aggressively and will seem reluctant to end the Fall
stage.
9.6.3. Using the Legato options
Legato is the name for the most common keyboard playing technique. It's when you put
your fingers down on the keyboard one by one, connecting each new note to the previous
one without a break. It is the opposite of staccato playing where you lift your finger(s) from
keyboard before pressing a new key.
A setting in Utility enables you to define how the Envelope and the Cycling Envelope will
behave when you play legato. When set to OFF the envelopes will restart every time you
add a note to the first key you hold down. When set to ON only the first key you press will
start the Envelope; the second and next key presses will use the contour of this first Envelope.
This applies to both mono and parophonic playing.
9.7. Freaky Cycling Envelope Suggestions
The real magic starts when you bring the Rise, Hold and Fall knobs under voltage control.
You can use the Matrix to modulate these knobs with an LFO or with pressure. Pressure
especially will give you a lot of control over the Rise and Fall stages of the envelope.
Note: Keep in mind that using the Matrix encoder you can make both positive-going and
negative-going voltages. If, for example, you apply a negative-going voltage to the Fall stage,
the Fall stage becomes shorter when you apply more pressure.
