MIDI播放器/合成器库为iPhone [英] MIDI player/synthesizer library for the iPhone

问题描述

有谁知道是否有一个自由/廉价MIDI播放器/合成器，我可以融入我的iPhone应用程序库？

Does anyone know if there is a free/cheap MIDI player/synthesizer library that I can incorporate into my iPhone application?

据我了解，iPhone不具有MIDI回放的本地支持。

As I understand it the iPhone doesn't have native support for MIDI playback.

要解决此限制我创建.caf声音样本的一个银行，我自己播放，但我真的很想提高执行，如果可能，使用MIDI。

To work around this limitation I've created a bank of .caf sound samples that I playback myself but I'd really like to improve the implementation and use MIDI if possible.

任何意见将是极大的AP preciated。

Any advice would be greatly appreciated.

由于二零一一年十月十日，就是因为iOS5中，苹果公司已经开始提供基本的API，用于播放MIDI文件。该API被称为MusicPlayer与MusicSequence一起检查了这一点：

Since 10 october of 2011, that is since iOS5, Apple has started delivering basic API for midi files playback. The API is called MusicPlayer along with MusicSequence Check this out :
