I'm sending a string of MIDI packets using MIDIPacketListAdd. I want to change the packets dynamically during playback, so I'm using a NSTimer to add each packet before the scheduled time the packet should go out.
The code works perfectly, the address of the current packet is updated correctly, I have verified that all the data is correct. However, no MIDI data is being sent when MIDIPacketListAdd is called from the timer. I add the first two packets before starting the timer to make sure that the packets are sent to MIDIPacketListAdd before they need to be played.
I'm very puzzled. Any suggestions?
Thanks, Tom Jeffries
