c - Query state of all Midi knobs on midiInOpen

Question

I have a MIDI controller with several knobs. Is it possible to query state of all values, which these knobs have, when I connect to the device using midiInOpen function without physically moving each of them?

Answer 1

没有标准的 MIDI 消息来查询控制器的当前状态；仅当发生变化时才发送消息。

除非您的控制器具有完全符合您要求的特定于供应商的扩展，否则这是不可能的。
