VSTplug slider

[wlangfor@uoguelph.ca]

Hi all, here's a better slider with only two modules.

It's very efficient and it is fully tested with automation. The only thing I have not tested is the default 0-1 reference in the preset module I'm not sure if it requires a 1-value to work.

Check that out, but it's the most simple yet, and furhermore by y using it a user can also use the slider while automating without it breaking!

I love the maple leaf - very patriotic! And it's certainly a lot better arranged inside than the stock ones!

My only criticism is that the mouse scaling means that the handle moves at a different speed to the mouse - I find that a little non-intuitive; as if the mouse isn't "grabbing" the control. That's quite easy to fix, though - you just need the "scaling" input of the DragY component to be derived from the slider's range of motion. I can't remember off the top of my head, but it's a proportional relationship between the slider's travel and maybe the GUI grid size to get them to match up. Alternatively, you could hide the mouse pointer so that no-one can see the difference!

Check it against an automation lane in your DAW. You can set a VST preset to any float value you like, but 0.0..1.0 is always assumed to be bottom..top of an automation "lane" - so if your DAW automation curves are drawing upside-down, invert whatever you're currently using.

PS) I had a look in one of my old sliders - the mouse scaling maths is just (1.0 / slider_travel), where the slider_travel is in the usual GUI grid units.

yeah, I knew about the automation; but sliders innately are backwards, up is 0 and down is 1.
But that mouse movement formula, I'd like to know that one please.

If it's not too much bother.

Ah, that's turned out to be really easy - you already had the range value calculated, so there was only one divide primitive to add! Here it is with that modification...

The main advantage is that when you re-size the slider, the mouse scaling adjusts automatically to fit, so there's no need to edit anything or provide a "sensitivity" property for the mouse.
