◆ read() [1/2]

uint32_t read ( )

inline

Try reading a 4-byte MIDI USB message.

◆ setTimeout()

void setTimeout ( microseconds timeout )

inline

Set the timeout, the number of microseconds to buffer the outgoing MIDI messages.

A shorter timeout usually results in lower latency, but also causes more overhead, because more packets might be required.
