@Chazrox I think a radial gradient would work. There should be a video about gradients on my YouTube channel I think, or maybe Patreon

Edit: actually a linear gradient might be better

ustk

@David-Healey Well so an SDK downgrade would be the best thing to test, at least to see if the process is the good one

@ustk said in AAX Build on MacOS:

Can your mac support a more recent OS?

I'm still on Ventura, so not sure a newer OS will help Lindon here.

ustk

@Lindon I guess you meant 2.8.0...

Can your mac support a more recent OS?

Can you try downgrading the SDK?

ustk

@dannytaurus Oh nice one!

Lindon

@ustk sigh well nope I compile that and I get the same problems...

Im using Sonoma 14.6.1 and XCode 15.4 and AAX SDK V2.0.8

..anyone think this is wrong? got a better suggestion?

David Healey

@dannytaurus No the column just lists the files. A one column browser is pretty easy to create with a viewport or panel though.

@ustk very sexy!

@Chazrox

I don't have a "clean" example.
This is old code too, so not a good example of good c++ node practices or anything like that.

But here is a c++ node with a global cable(s) set up.

I've had no problems before, with updating existing c++ headers when adding more global cables.

If you make sure that the generated global cable code is up to date.
When you create more cables, you need to re-generate the global cable c++ code in Hise and update those parts in the c++

This generated stuff needs to be kept up to date with the cable names and IDs in your Hise project:

enum class GlobalCables { grainpos = 0 };
    using cable_manager_t = routing::global_cable_cpp_manager<SN_GLOBAL_CABLE(94428153)>;

^ Here, only one global cable exists, however when you add more global cables to your Hise project, this code will need regenerating / updating with the new names and IDs of the cables in your Hise project.

C++ node example (using one global cable):

// FILE: Griffin_GrainOsc.h
/*
    Granular OSC node: per-voice state & note-reactive pitch.
    Each voice owns a Granulator instance via snex::PolyData so reset/prepare
    are scoped to the active voice. Pitch maps so that MIDI note 60 plays the
    sample at its original pitch / speed
