Affecting midi CC values using a UI element? [solved]

[andioak]

How can I affect the internal midi CC value of a controller using a knob on the ui?

I got this:

onControl:

if (number == mod_wheel)
    {
    	Synth.sendController(3, value); // sending ui-knob´s value to CC3
    }
}

When I then try to "Synth.getController()" ... well I find no such thing. Just the Message.xxxx stuff. They only work in the onController CB, and by doing the above we do not get a onController call.

What´s the answer?

Generally you shouldn't use the generic onControl callback (it's deprecated) use a standalone callback per control. Although this is not related to your question.

What do you get if you put Console.print(value); inside that if statement?

@d-healey Thanks for replying.

I get what you´d expect, the correct value outputted, as any other ui control. Although the value is the input value of the ui control, so the instigator so to speak. I cannot really verify that I am actually affecting the CC of the synth, cause I find no actual getControllerValue or any equivalent that can be accessed via the onControl or outside of the onController callback. Not yet anyway.

Why is the onControl callback deprecated? Cause it´s faster with inline functions?

[d.healey]

@andioak Because we have the newer individual callbacks which are easier to maintain in larger projects. If you use the generic callback in a large project you end up with a massive switch statement which is quite messy and isn't very reusable.

Why do you want to use a CC to control a knob?

That´s not the question. I want to control a midi CC using a ui-knob. Not the other way around. But now that you say it, I want that too. To control a ui-knob using a CC, the mod wheel.

Like Kontakt or most virtual instruments update the mod wheel on the ui when you use the keyboard´s mod wheel.

So it´s both ways I want to do. The first thing now is the updating of the internal CC when I use the ui-knob.

Maybe I know this already, the CC assignment? Perhaps it has to be connected and saved in the presets?

[d.healey]

Oh I get it now. HISE can't send MIDI out, so you can't do that.

That you can do. Just change the knob's value in the on controller callback.

Hmm, what can I not do? I dont want to control the midi keyboard at all, just control the internal midi cc´s value using the ui.

Okay, thanks. I´ll try that out.

One little thing: the Message and MessageHolder, are they only accessible in the onController callback?

[d.healey]

@andioak They are available in all the MIDI callbacks, on note on, on note off, on controller.

Aha, jeeez. Thats great but I need to set a midi cc from a ui element, but the thing is that the statement Synth.sendController(3, value); does not generate a onController callback. So perhaps I have to go through a onNote callback and use a key instead? I mean I could generate a note and read the velocity via a conversion, right? (seems elaborate)

Not possible, no MIDI out from HISE.

Where would that go out from HISE? I don´t get that comment.

[andioak]

What is this about then:

Synth.sendController(3, value);

That´s an internal change of a cc to the synth api.

@andioak I'll make a snippet, give me a few minutes.

@d-healey Thanks.

The Synth.sendController() function sends controller messages to the internal synth. So you can controller MIDI modulators. If you expan the gain modulators in the snippet and move the knob you'll see the CC modulator on CC3 being affected.

@d-healey
Thanks for the snippet, yes I see how it is modulated now! So the UI to internal cc is solved, many thanks.
