Sounds good to me!

Terminology

AudioToolbox: A framework to record and play audio

MIDI (Music Instrument Digital Interface): A standard for musical instruments, and can be used to play MIDI instruments on Apple Devices

MusicSequence: The music sequence previously attached to the audio engine

MusicTrack: Several music events, each timestamped using a series of beats

Motivation

I’ve created several Apps that require a small piece of audio to play (a *bing* or *chime*. I’ve experimented with AVPlayer and AVAudioPlayer, and looking around on the web for public domain chimes.

It wasn’t that fun I’ll admit that. The performance wasn’t where I wanted it to be, and the quality of the samples I used.

Well.

I’m a better developer now (probably). I can find a better solution (probably).
