Start/stop don't pass MIDI-Through

[Darryl]

What I also do not understand, why it is sending out the clock at channel 4 (also all other events from the NDLR) as I am only using the drone for this example (hence the single note on command) and would have expected channel 3

Clock and Start/Stop/Continue message are global (System Real-Time) messages and not associated with a channel. You will have to ask the MIDI-Ox people why there's a channel on there.  It probably just shows the channel from the prior message because they don't clear it between messages. Despite its flaws, MIDI-Ox has been an indispensable tool for us. 

I think there's a little confusion here. The second column, IN, is actually a number indicating which MIDI device the message came from. So, for the above, the clock messages are coming from device 4, one of the NDLR MIDI USB devices. There's a separate column, CHAN, that shows the MIDI channel for the message if there is one.

I agree that MIDI-OX is indispensable.

Ah yes, thanks for clarifying that.
