Envelope settings
In the lower part of the voice editor, the envelope for the currently selected
tone can be set using the knobs.
Please note that an envelope always refers to the entire tone. Separate
envelopes for each sample are not supported by the U.
The envelope of the U is basically built up according to the following
scheme:
This scheme is already known from other Roland devices and corresponds
most closely to an AHDSR envelope. The envelope has a few peculiari-
ties, which we will discuss in more detail later.
T1
represents the time until the level of the sample has risen to the value
L1
. T1 is comparable to the
attack time
and L1 to the
attack level
. The
course of this part of the envelope is always linear.
T2
is the time until the level has changed from L1 to
L2
. L2 can be higher
or lower than L1. If both levels are the same, it is a classic
hold
. The
course of this part of the envelope is also always linear.
T3
is the time in which, starting from L2, the
sustain
level L3 occurs. This
curve is either concave, if L2 is larger than L3, or convex, if L2 is smaller
than L3. The degree of curvature can be adjusted via the Shape parame-
ter.
The last parameter,
T4
, corresponds to the classic Release Time and rep-
resents the time it takes for the sample to drop from sustain level L3 to
zero. This time starts as soon as the keyboard key is released.
The expected envelope is displayed in blue in the waveform window when
you move the mouse over one of the controls. In addition, a tooltip shows
