How do I send Meta Messages that has more than 3 bytes data with Pygame.midi?

Question

I'm trying to send Meta Messages has more than 3 bytes data. But an error is appeared.

Too many data bytes (8) in event no. 0.

It's because pygame.midi write method can send data till 3 bytes.

Is it impossible?

i use python 2.7, pygame 1.9.4 and OSX 10.13.6(High Sierra)

Answer 1

根据源文件 ，您的消息字符串的长度超过了允许的最大长度4 （8> 4）

Answer 2

Write is used only for channel messages.

To output SysEx messages, use WriteSysEx :

out.WriteSysEx(0, '\\xF0\\x7D\\x10\\x11\\x12\\x13\\xF7')
out.WriteSysEx(0, [0xF0, 0x7D, 0x10, 0x11, 0x12, 0x13, 0xF7])

Meta messages are not MIDI messages, and are never sent over MIDI. Your program itself has to handle them.
