<h2><a class='anchor' name='description'>Description</a></h2>
<p>Write a signal to a bus.
<p>Note that using the Bus class to allocate a multichannel bus simply reserves a series of adjacent bus indices with the Server object's bus allocators. abus.index simply returns the first of those indices. When using a Bus with an In or Out UGen there is nothing to stop you from reading to or writing from a larger range, or from hardcoding to a bus that has been allocated. You are responsible for making sure that the number of channels match and that there are no conflicts.<div class='note'><span class='notelabel'>NOTE:</span> Out is subject to control rate jitter. Where sample accurate output is needed, use <a href="./../Classes/OffsetOut.html">OffsetOut</a> .</div>
<p>See the <a href="./../Reference/Server-Architecture.html">Server Architecture</a> and <a href="./../Classes/Bus.html">Bus</a> helpfiles for more information on buses and how they are used.<h2><a class='anchor' name='classmethods'>Class Methods</a></h2>
