Is there a way to pickup host transport messages directly within a custom node??

[Orvillain]

I'd like to be able to poll transport start/stop and tempo changes from within a node. Is that possible, or do I have to use a data cable to feed messages from the top Hise layer?

+1 Would really like to know about how to do this.

Definitley a good place to start experimenting is the tempo_sync node and the tempo_sync_base class it inherits from.

I just came across this too, which seems relevant.

@Orvillain Nice find.

Honestly up until now I have just been placing my C++ nodes inside of scriptnode and using that for interacting with transport/tempo information. Not always the most ideal solution but it does work in most scenarios.

@HISEnberg If in doubt, stalk @griffinboy

So following Chris's comment in that thread, it sounds like the node needs to inherit from:

public hise::TempoListener

And then you write a custom callback. Something like:

void tempoChanged(double newTempo) override
    {
        
        // yo bro, do a thing here innit fam bruv dudemeister
        for (auto& t : data)
	{
		t.bpm = newTempo;
		t.refresh();
	}
     }

But I haven't tried it yet.
