/**

|
* @file sequence.c
|
|
*
|
|
* This file implements a set of high-level audio sequence commands that allow sequences to be modified in real-time.
|
|
* These commands are intended to interface external to the audio library.
|
|
*
|
|
* These commands are generated using `AudioSeq_QueueSeqCmd`, and a user-friendly interface for this function
|
|
* can be found in `seqcmd.h`
|
|
*
|
|
* These commands change sequences by generating internal audio commands `AudioThread_QueueCmd` which allows these
|
|
* sequence requests to be passed onto the audio thread. It is worth noting all functions in this file are
|
|
* called from the graph thread.
|
|
*
|
|
* These commands are not to be confused with the sequence instructions used by the sequences themselves
|
|
* which are a midi-based scripting language.
|
|
*
|
|
* Nor are these commands to be confused with the internal audio commands used to transfer requests from
|
|
* the graph thread to the audio thread.
