Command Blocks are Csound ORC code with special directions to Blue on how to processes them. The are available to use only within the Global Orchestra areas of Instruments (not to be confused with the global orchestra area in the globals manager tab) and were created to help users build fully-encapsulated instruments, such that an instrument and all of its necessary parts could be grouped together.


This feature has largely been made unnecessary due to new Csound programming practices that have developed since this was initially introduced. This feature is left in Blue though to support legacy projects.
