How about sideway fwd/back arrows. The sideway movement of the bar
indicates something like that

Not all values are on a scale. Channel one is no more nor less than
channel 16. Sound 128 is not nescessarily fatter or thinner than any
other sound. So in those cases the bar would get in the way.

Also having the bar go thru a number that you might like to read is not
so perfect. Is that a 3 or is it an 8? And where did that tiny decimal
point go?

Fading the whole background/foreground could be an option. The idea
being that a led behind the widget emits more light as the values get
higher.

So plus/minus buttons is kind of off, no matter the esthetics?

I think page up/down is standard behaviour for large steps in GTK.
Arrow left/down decrements, right/up increments.

Click and Hold spins thru all values, first with the small increment
value and then after some time with the page size.
