the issue I am having is that the messages are not actually triggering the clips... I am seeing all the osc being sent, but the session does not necessarily execute the command on the backup.
With the Osc output all preset, you get more messages you actually need on the slave.
This particular case happens because you get a selectedclip/connect and a layers/clips/connect at about the same time. So depending on the timing, it can happen that the clip that was playing and is selected is relaunced cancelling the new clip's launch in the same layer.
I have created an OSC master preset, that has all basic controls mapped.
You can add your own custom messages paricular to your workflow, like for instance controls for effects.
