Slider value snapping please

[orange]

@Christoph-Hart Can we add value snapping feature to the slider please?

For example: There is a knob with a value range between 75 and 15000.

The user should be able to choose whether these values ​​are continuous or snapped with a switch.

So if the user selects snapped values, the slider will jump to the previously defined snap values (for example: 75, 150, 500, 1040, 3600, 15000).

If the user selects continuous mode, then the slider will be like we all know.

[Christoph Hart]

@orange you should be able to do that with a broadcaster attached to the slider mouse callback and then round the values in the drag callback.

[orange]

@Christoph-Hart I didin't know that. Is there any reference or snippet for this?

[ustk]

@orange Here's an example snippet using a broadcaster as @Christoph-Hart suggested and a hidden knob (otherwise it's glitchy). But since my solution can also be done from within the knob's CB I don't understand why a broadcaster should be used here... Or maybe it has advantages I can't see and I use it wrongly?

I don't understand why a broadcaster should be used here...

You don't need to write a callback if you just connect it to a module parameter. Also it's a bit weird setting the value in a callback that reacts on a value (it will happen in automation too).

The broadcaster just adds that functionality without messing with the original function so it's more modular and reusable.

@Christoph-Hart said in Slider value snapping please:

Also it's a bit weird setting the value in a callback that reacts on a value (it will happen in automation too).

Yeah I agree but doing so in a broadcaster also creates glitches
I wanted to force the knob's value by snapping it but it's glitchy in both solutions, hence the reason I used a hidden knob.

Of course the broadcaster spares a callback, but just using a callback is easier and less verbose than the broadcaster alone in this case

[ustk]

Another simple solution:

[Christoph Hart]

@ustk Yeah that might be the best one. I would suggest to interpolate between the array indexes if snap is off like this:

local freq;
	
	local idx = parseInt(Math.floor(value));
	
	if (snapBtn.getValue())
		freq = v[idx];
	else
	{
		local lo = v[idx];
		local hi = v[idx+1];
		local alpha = Math.fmod(value, 1.0);
		local interpolated = lo * (1.0-alpha) + hi * (alpha);
		freq = interpolated;
	}

This will retain the position to the snap one.

@ustk All three solutions are great, I will choose the latest one. Thank you!

@Christoph-Hart Great example! Thank you
