Use the (Tcl) event loop. If you run the interface in a separate
process, then you have chimera's event loop invoke a callback when
there is data to be read on the socket connecting the two
processes. That is what's done to implement the --send command line
option. See DBPuppet/tcl_sockets.py for details.<br>
<br>
An alternative would be to use threads where the queue is checked
every frame. See ReadStdin/__init__.py for details there.<br>

<p>I should be able to use python midi libraries for access. </p>
<p><br>
</p>
<p>This leads to the problem of the midi implementation, and a
question as to a similar implementation for chimera2.</p>
<p><br>
</p>
<p>One implementation would insert into the event loop, another
approach could be tied to a frame/trigger callback. </p>
<p><br>
</p>
<p>Any suggestions?</p>
