C++ MidiDevice::recordEvents方法代码示例

//.........这里部分代码省略.........
				// p3.3.50 Removed
				//int channel = r->channel;
				// NOTE: TODO: Special for input device sysex 'channel' marked as -1, ** IF we end up going with that method **.
				// This would mean having a separate 'System' channel listed in the routing popups.
				// The other alternative is to accept sysex from a device as long as ANY regular channel is routed from it,
				//  this does not require a 'System' channel listed in the routing popups.
				// But that requires more code below... Done.
				//if(channel == -1)
				//channel = MIDI_CHANNELS; // Special channel '17'
				//  continue;

				//int devport = dev->midiPort();

				// record only from ports marked in portMask:
				//if (devport == -1 || !(portMask & (1 << devport)))
				//if (devport == -1)
				//      continue;

				//MREventList* el = dev->recordEvents();
				//MidiFifo& rf = dev->recordEvents();
