Drumstick 介绍
Drumstick 是一个ALSA的音序器 (MIDI 接口)的C++封装库
示例代码:
#include <QApplication> #include <drumstick.h> int main(int argc, char **argv) { QApplication app(argc, argv, false); // create a client object on the heap drumstick::MidiClient *client = new drumstick::MidiClient; client->open(); client->setClientName( "MyClient" ); // create the port drumstick::MidiPort *port = client->createPort(); port->setPortName( "MyPort" ); port->setCapability( SND_SEQ_PORT_CAP_READ | SND_SEQ_PORT_CAP_SUBS_READ ); port->setPortType( SND_SEQ_PORT_TYPE_MIDI_GENERIC ); // subscribe the port to some other client:port port->subscribeTo( "20:0" ); // or "name:port", like in "KMidimon:0" // create an event object on the stack, to send a note on message drumstick::NoteOnEvent ev( 0, 66, 100 ); // (channel, note number, velocity) ev.setSource( port->getPortId() ); ev.setSubscribers(); // deliver to all the connected ports ev.setDirect(); // not scheduled, deliver immediately client->output( &ev ); // or outputDirect() if you prefer not buffered client->drainOutput(); // flush the buffer // close and clean client->close(); delete client; return 0; }
