Title: Receiving Timing Clock messages?
Post by nsfx on Mar 31^st, 2010, 12:45am

Is it possible to receive Timing Clock messages via a MoxScript object? I've tried both the polling and event methods, but I can't get Timing messages to pass on to the script. Note messages and CC messages get to the script just fine. I have midi transport enabled on my DAW outputting to Midi Yoke port 1, and I see these timing codes flying by in the MIDI-OX window on the correct MIDI port, but I can't get them to the script. Is there an option to enabled this or something? or am I missing something else?

Thanks!

Just some extra info... If I connect In From Midi Yoke 1 -> Out To Midi Yoke 1, I see a few messages get to the script, but this creates MIDI feedback (as expected) and kills the script. I tried connecting In From Midi Yoke 1 --> Out To Midi Yoke 2 instead, and receiving input via the In From Midi Yoke 2 port in the script, but nothing appears! Can someone give an example on how to get a DAW time code to a MIDI-OX script using Midi Yoke? Thanks.

MIDI Clocks come in pretty fast: 24 per MIDI beat (quarter note) -- speed is also dependent on tempo. I think polling might be too slow to capture these with any timing accuracy, but the event method should see them. What you would see in a script would be (assuming Event method):

dim nClocks

nClocks = 0

' . . .

Sub Sink_MidiInput( ts, port, stat, dat1, dat2)

' Count timing clock
If stat = &hF8 Then
nClocks = nClocks + 1
End If

' send message back out all open ports
mox.OutputMidiMsg -1, stat, dat1, dat2

End Sub

Thanks for the reply Jamie. My problem isn't with the syntax -- I already have MIDI messages coming into the script via the event method. For some reason, *JUST* timing clock messages aren't making it to the script even though I see them in the monitor window. Any idea why that might happen?

Thanks again.

Alright. I finally figured it out. I don't remember setting these options, but in the "MIDI Filters..." window, System Realtime messages were being filtered out. I unchecked everything in this window and then it worked.
