// ayFX replayer sample
//─────────────────────────────────────────────────────────────────────────────
// This sample program showcase the use of the ayFX module to play sound effect.
// The replaye support both sound banks and individual sound file.
// See ayFX editor for more detail: https://shiru.untergrund.net/software.shtml
// Note: This program showcase the use of ayFX replayer with PT3 msic replayer
// but ayFX can be use as stand alone.
