<p>insglobal —
An opcode which can be used to implement a remote
orchestra. This opcode will send note events from a source
machine to many destinations.

<h2>Description</h2>
<p>
With the <a class="link" href="insremot.html" title="insremot"><em class="citetitle">insremot</em></a> and
<span class="emphasis"><em>insglobal</em></span> opcodes you are able to perform
instruments on remote machines and control them from a master
machine. The remote opcodes are implemented using the
master/client model. All the machines involved contain the same
orchestra but only the master machine contains the information
of the score. During the performance the master machine sends
the note events to the clients. The
<span class="emphasis"><em>insglobal</em></span> opcode sends the events to all
the machines involved in the remote concert. These machines are
determined by the <a class="link" href="insremot.html" title="insremot"><em class="citetitle">insremot</em></a>
definitions made above the <span class="emphasis"><em>insglobal</em></span>
command. To send events to only one machine use <a class="link" href="insremot.html" title="insremot"><em class="citetitle">insremot</em></a>.

<h2>Syntax</h2>

</div>
<div class="refsect1">
<a id="idm281472922931080"></a>
<h2>Initialization</h2>
<p>
<span class="emphasis"><em>isource</em></span>
-- a string that is the intended server computer (e.g. 192.168.0.100). This is the source host which generates the events of the given instrument(s) and sends it to all the machines involved in the remote concert.
</p>
<p>
<span class="emphasis"><em>instrnum</em></span>
-- a list of instrument numbers which will be played on the destination machines

Internally this opcode makes use of the gethostname and
gethostbyname functions to determine the client's and server's
IP address for checking which messages are for which machine.
If a computer has more than one IP address there is no way to
control which IP address is found.
