Pitchwheel & Modwheel graphics &linking.

staiff

hello !
linking modwheel & pitchwheel with graphics is not implemented yet ?
is there a way to do this with script ?

thanks.

Christoph Hart

That should be easy to achieve. Just update your graphics from the onController() callback:

Pitchwheel

Content.makeFrontInterface(600, 500);

// This is important or it will render the graphics on the audio thread...
Synth.deferCallbacks(true);

const var ModwheelDisplay = Content.addPanel("ModwheelDisplay", 38, 60);
// [JSON ModwheelDisplay]
Content.setPropertiesFromJSON("ModwheelDisplay", {
  "width": 50,
  "height": 180
});


// [/JSON ModwheelDisplay]
const var PitchWheelDisplay = Content.addPanel("PitchWheelDisplay", 110, 60);
// [JSON PitchWheelDisplay]
Content.setPropertiesFromJSON("PitchWheelDisplay", {
  "width": 50,
  "height": 180
});
// [/JSON PitchWheelDisplay]

ModwheelDisplay.setPaintRoutine(function(g)
{
	g.fillAll(0xFF222222);
	g.setColour(0xFF666666);
	
	var h = this.getValue() * this.getHeight();
	
	g.fillRect([0, this.getHeight() - h, this.getWidth(), h]);	
});

PitchWheelDisplay.setPaintRoutine(function(g)
{
	g.fillAll(0xFF222222);
	g.setColour(0xFF666666);
	
	var h = 0.5 - this.getValue();
	var offset = Math.min(1.0 - this.getValue(), 0.5) * this.getHeight();
	
	g.fillRect([0, offset, this.getWidth(), Math.abs(h) * this.getHeight()]);
});

function onNoteOn()
{
}
function onNoteOff()
{
	
}
function onController()
{
	if(Message.getControllerNumber() == 1) // Modwheel
	{
		ModwheelDisplay.setValue(Message.getControllerValue() / 127.0);
		ModwheelDisplay.repaint();
	}
	if(Message.getControllerNumber() == 128) // Pitchwheel
	{
		PitchWheelDisplay.setValue(Message.getControllerValue() / 127.0 / 127.0); // 14bit resolution
		PitchWheelDisplay.repaint();
	}
}
function onTimer()
{
	
}
function onControl(number, value)
{
	
}

thanks !
i will use png grafics (filmstrip) instead of paint grafics.
some modifications to do.
i'll do this this afternoon.

staiff

not working for me ... :(

Christoph Hart

What is not working for you? The example above or your filmstrip implementation?

staiff

in your example: onController() callback <= maybe made mistake here.
in my example: using graphical png knob/slider linked to CC1 &CC128 => made more mistakes i feel :D

staiff

don't find the solution.
If someone has already used it or have an example... thanks in advance.

Christoph Hart

You really need to be more precise what's not working. "Made more mistakes" is pretty vague :)

Please post your script and the error message from the console, otherwise it's just shooting in the dark.

staiff

ok i'm just the stupidiest man in this world. i put the controller script in the init, and wrote an "exotic" script in Controller.
your code with your grafics works now.
so i'm actually try to replace your paint graphics by a .png filmstrip

Christoph Hart

Ah OK, you've pasted the entire code in the onInit callback, however this was supposed to be the whole script (you've ended up with two onController definitions and the empty one overwrote the one you've pasted.

Just use this snippet:

Copy this into the clipboard, then File -> Replace with clipboard content.

(Note to myself: never post a entire script again) :)

Also you've got some weird syntax errors in your script, so it's no wonder it isn't working (basically you're approach should be correct though).

staiff

lol,
i just edited my previous message to say like you that i place all codes in OnInit. Stupid i am !!!

no, you can post entire script, but not for a "Forrest gump" like me :D

ok. try to replace by .png filmstrip image now

EDIT:
ok, working with .png images. at this time it's a knob. So i have a question. Modwheel and Pitchwhell are not the same. For modwheel i will create a wheel starting to 0 (down) and going to 127 (up). that's ok. But for the pitch i must do another wheel starting at center or the same wheel will be "centered" (like the knob ?)

I Have A Small Problem Here, The Value Of Pitch Bend Panel is Always Goes to 0
And It Goes Down. ( Just Click on Pitch bend, And Then Hit Compile Icon Or F5)
Can someone Fix The Pitchbend?
Thanks a lot

@Natan said in Pitchwheel & Modwheel graphics &linking.:

Pitch Bend Panel is Always Goes to 0

You mean the middle position?

Natan

Hello Sir David, Yes Sir, It Wont stay on Middle As Default

d.healey

@Natan Works here

Peek 2021-10-28 10-50.gif

Natan

@d-healey Yeah It Works
I Mean Once you open the snippet, It Goes Down.
I want it to stay in Middle

Or just hit the Rebuild Interface
It Jumps to Down

d.healey

@Natan Just add pnlPitch.setValue(8192); After the panel is created.

Excellent That did the Job
