Building an ARP - TransportHandler

[Lindon]

So I'm building an Arp, and I want it to be able to handle Tempo changes, as well as start on beat and start on bar stuff, so I think I need the TransportHandler, but Im getting nowhere with it.

The demo snippet in the documentation works at least now - when I start/stop the external DAW simulator, but the documentation is its usual terse uncommunicative self....

Has anyone used this and can say how it works? or has a snippet?

So specifically Im looking at:

th.setEnableGrid(true, 18); <--- whats this "18" here?

th.setOnGridChange(false, function(num)
{
	Console.print("grid event");
});

This does nothing....so its not right in some way....

@Lindon said in Building an ARP - TransportHandler:

th.setEnableGrid(true, 18); <--- whats this "18" here?

the 18 is equal to 1/64T, if you not use "HISE_USE_EXTENDED_TEMPO_VALUES=1" in your Hise build, then the lowest note value 1/64T will be the number 23

@ulrik thanks -- I have it running now.

Im still confused about how to get it running without the transport running, so I assume that's not possible, and I have 2 arps so I'd like 2 transport handlers but again i assume we are (just like Kontakt) stuck with working it all out in the one call back..

@Lindon this is a small snippet, TransportHandler will start/stop with the transport
it will also start/stop dependent on pressed keys

So if keys down, the gridChange function will start counting amount of 1/64T's (Clock), and if you start the transport the "Clock" will adjust to the transport (playHead)

@ulrik thanks - looking at this now..

what are arg2 and arg3 in the callback?

@Lindon actually I don't remember, I guess isPlaying and something?
