## Introduction
csound-nstrexists provides a simple way to check whether an instrument number exists in the orchestra, at i-rate or k-rate. An example csd is provided in the examples/ directory demonstrating i and k-rate operation.
-This depends on changes in commit cca2bd90bffc5c36499c74734e37ec256dc60924 on 2019-09-12 so it will not work with builds older than that.
