<h2>Description</h2>
<p>
Constructs a user-definable envelope. It is the same
as <a class="link" href="transeg.html" title="transeg"><em class="citetitle">transeg</em></a>,
with an extended release segment.

<a id="id3300041"></a>
<h2>Initialization</h2>
<p>
<span class="emphasis"><em>ia</em></span> -- starting value.
</p>
<p>
<span class="emphasis"><em>ib, ic,</em></span> etc. -- value after <span class="emphasis"><em>idur</em></span> seconds.
</p>
<p>
<span class="emphasis"><em>idur</em></span> -- duration in seconds of first segment. A zero or negative value will cause all initialization to be skipped.
</p>
<p>
<span class="emphasis"><em>idur2,... idurx</em></span> etc. -- duration in seconds of segment
</p>
<p>
<span class="emphasis"><em>itype, itype2,</em></span> etc. -- if 0, a straight line is produced. If non-zero, then <span class="emphasis"><em>transegr</em></span> creates the following curve, for <span class="emphasis"><em>n</em></span> steps:
</p>
<div class="literallayout">
<p><br />
ibeg + (ivalue - ibeg) * (1 - exp( i*itype/(n-1) )) / (1 - exp(itype))<br />

<div class="refsect1" title="Performance">
<a id="id3300108"></a>
<h2>Performance</h2>
<p>
If <span class="emphasis"><em>itype</em></span> > 0, there is a slowly rising (concave) or slowly decaying
(convex) curve, while if <span class="emphasis"><em>itype</em></span> < 0, the curve is fast rising (convex) or
fast decaying (concave). See also <a class="link" href="GEN16.html" title="GEN16"><em class="citetitle">GEN16</em></a>.
</p>
<p>
This opcode is the same as
of <a class="link" href="transeg.html" title="transeg"><em class="citetitle">transeg</em></a>
with an additional release segment triggered by a MIDI noteoff
event, a negative p1 <a class="link" href="i.html" title="i Statement (Instrument or Note Statement)"><em class="citetitle">note event</em></a> in the score or
