Yes, that's the way the current implementation works -- there is no schedule-ahead for sources. Unfortunately you'll have to do your own scheduling.

I have a bug to address this ...

Best,

Folks.

I am scheduling time sensitive data with CoreMidi. I prepare my data, then schedule it with 'MidiSend' with a defined timestamp for the time at which I want it actually sent.

This works fine with MidiSend, going to real Midi ports, or IAC buses.

However, when I try to do the same thing with a Virtual midi source (created by my app), using 'MidiReceived', the timestamp is ignored, and the packet gets sent immediately, instead of waiting for the timestamp.

I treat my 'virtual source' in exactly the same way as a real output endpoint. Is this a bug, or do I need to do things differently with MidiReceived. The port is working perfectly in all aspects apart from this forward scheduling issue.

Any ideas ?

Cheers

Mark Gilbert.
