Thanks David,
I have tried the sample codes in that link. it always logs “0” in
MyMIDIReadProc().
because that I’m using ARC ?
but when I use MIDIReceive() to trigger MyMIDIReadProc() it could be logs
correct value:
-(IBAction)testReceive:(id)sender{
Byte buffer[1024];
MIDIPacketList *packetlist = (MIDIPacketList*)buffer;
MIDIPacket *currentpacket = MIDIPacketListInit(packetlist);
Byte msgs[3] = {0x90, 40, 100};
currentpacket = MIDIPacketListAdd(packetlist, sizeof(buffer),currentpacket,
0, 3, msgs);
MIDIReceived(self.sourcePoint, packetlist);
}
it works, but I can use this way.
Thanks
Tin
