Generated Sound Commands
Overview of the generated-tone, PLAY-string, mix, waveform, envelope, and instrument commands.
Description
Generated sound commands synthesize audio directly through sfxlib. They are useful for simple tones, retro-style PLAY strings, game sound effects that do not need external files, and quick diagnostics that prove the sound path works.
