Slider with log ticks?

It works, but after implementing it the GUI looked pretty bad with 30 sliders, side by side, with scales. Very cluttered.

Yeah, but that's sort of like what a sound board looks like, right? Maybe you can vary the appearance by grouping sets of related sliders and giving them a common color for their slider handles, or putting them in group boxes with different background colors. It doesn't have to be garish.

Or if all of the sliders don't have to be displayed at the same time, dividing them into groups on tabs, each tab controlling a specific set of functions.

Or if all the scales are the same, turning off tick labels and/or ticks for all except the ones on the ends of the rows.

Agreed, sound boards typically an intimidating array of knobs, buttons, indicators, and sliders.

All of your ideas are possibilities. Once I get the core of the application fleshed out I'll probably take another look at the ticks and labels.

As for the tab idea...I already have tabs for each mixer, so I'd have to have a tab widget in each mixers tab. Not sure how much layering becomes annoying and/or confusing.

But that's the sort of things that need to be worked out with GUI design.
