如何从我的 iOS 应用程序向 Mac 应用程序发送 MIDI 或 OSC 信号?
我正在考虑编写一个 iPhone/iPad 应用程序来模拟 MIDI 控制器。我知道已经有很多可用的,但我仍然想自己做。我对此有几个问题:
- 我对 MIDI 了解一点,但我最近听说过 OSC。显然,几乎所有 DJ 软件应用程序都支持 MIDI,但 OSC 是否具有使其引人注目的关键优势?
- 例如,我的 iOS 应用程序是否可以将 OSC 消息直接发送到 DJ 应用程序,而无需通过托管代理应用程序(如大多数远程处理应用程序)?用MIDI可以吗?
- 如果我被迫通过安装在主机上的服务器应用程序,我已经阅读过有关在 iOS 和我的主机代理之间进行通信的 Bonjour 和 TCP 套接字的信息,但是我的主机代理如何将 MIDI 或 OSC 信号发送到 DJ 应用程序?它必须伪装成虚拟 MIDI 设备吗?有可用的库吗?在 MacOSX 上?在 Windows 上?
I'm thinking of writing an iPhone/iPad application to emulate a MIDI controller. I know there are already quite a few available but I still want to do my own. I have several questions about that:
- I know a little bit about MIDI, but I've recently heard about OSC. Obviously MIDI is supported by almost all DJ software applications, but does OSC have a critical advantage that makes it compelling?
- For example, is it possible for my iOS application to send OSC messages directly to the DJ application without going through a hosted proxy application (like most remoting applications)? Is it possible with MIDI?
- If I'm forced to go through a server application installed on the host machine, I've read about Bonjour and TCP sockets to communicate between iOS and my host proxy, but how can my host proxy send MIDI or OSC signals to DJ applications? Does it have to pose as a virtual MIDI device? Are there libraries available for that? On MacOSX? On Windows?
