<p>compilestr —
compiles a new orchestra passed in as an ASCII string
</p>

<a id="idm281472945837640"></a>
<h2>Description</h2>
<p>
Compilestr will compile one or more instruments at init time, which will be added to the running engine. In case of
existing instrument numbers or names, these will be replaced, but any instance still running of the old instrument
definition will still perform until it terminates. Only new instances will use the new definition.
Multi-line strings are accepted, using {{ }} to enclose the string.
